Chapter 3Using The Recorder Functions

About this Chapter

This chapter provides a step-by-step introduction to therecorder functions of the test tool. The introduction givesexamples to show how to use the menus and performbasic operations.

Opening the Recorder Main MenuFirst choose a measurement in scope or meter mode.Now you can choose the recorder functions from therecorder main menu. To open the main menu, do thefollowing:

1 Open the RECORDER main menu.(See Figure 16.)

Figure 16. Recorder Main Menu


28

Plotting Measurements Over Time(TrendPlot™)Use the TrendPlot function to plot a graph of Scope orMeter measurements as function of time.

Note

Because the navigations for the dual inputTrendPlot (Scope) and the single input TrendPlot(Meter) are identical, only TrendPlot (Scope) isexplained in the next sections.

Starting a TrendPlot Function

To start plotting a graph of the reading over time, do thefollowing:

1 Apply a signal to the red BNC input A and turnon Reading 1 in scope mode

2 Open the RECORDER main menu.

3 Highlight Trend Plot (Scope).

4 Start the TrendPlot recording.

The test tool continuously records the digital readings ofthe input A measurements and displays these as a graph.The TrendPlot graph rolls from right to left like a paperchart recorder.

Observe that the recorded time from start appears at thebottom of the screen. The present reading appears ontop of the screen. (See Figure 17.)

Note

When simultaneously TrendPlotting tworeadings, the screen area is split into twosections of four divisions each.

Using The Recorder FunctionsPlotting Measurements Over Time (TrendPlot™) 3

29

Figure 17. TrendPlot Reading

When the Scope is in automatic mode, automatic verticalscaling is used to fit the TrendPlot graph on the screen.

5 Set RECORDER to STOP to freezethe recorder function.

6 Set RECORDER to RUN to continue.

Displaying Recorded Data

When in normal view (NORMAL), only the nine mostrecently recorded divisions are displayed on screen. Allprevious recordings are stored in memory.

VIEW ALL shows all data in memory:

7 Display an overview of the fullwaveform.

Press repeatedly to toggle between normal view(NORMAL) and overview (VIEW ALL)

When the recorder memory is full, an automaticcompression algorithm is used to compress all samplesinto half of the memory without loss of transients. Theother half of the recorder memory is free again tocontinue recording.


30

Changing the Recorder Options

At the right bottom of the display you can choose todisplay the time elapsed from start and the actual time ofthe day.

To change the time reference, proceed from step 6 asfollows:

7 Open the Recorder Optionsmenu.

8 Select Time of Day and jump tothe next field.

Now the recorded time and the current time appear at thebottom of the screen.

The options Reading 1 and Reading 2 allow you toselect the scope readings to be recorded. (Or one metermeasurement when in TrendPlot meter mode.)

To continue without making further changes:

9 Close.

Turning Off the TrendPlot Display

10 Exit the recorder function.

Using The Recorder FunctionsRecording Scope Waveforms In Deep Memory (Scope Record™) 3

31

Recording Scope Waveforms In DeepMemory (Scope Record™)The SCOPE RECORD function is a roll mode that logs one ortwo long waveforms. This function can be used to monitorwaveforms like motion control signals or the power-onevent of an Uninterruptable Power Supply (UPS). Duringrecording, fast transients are captured. Because of thedeep memory, recording can be done for more than oneday. This function is similar to the roll mode in manyDSO’s but has deeper memory and better functionality.

Starting a Scope Record Function

1 Apply a signal to the red BNC input A.

2 From the Recorder main menu,highlight Scope Record.

3 Start the recording.

The waveform moves across the screen from right to leftlike a normal chart recorder. (See Figure 18.)

Chapter 4Using Replay, Zoom and Cursors

About this Chapter

This chapter covers the capabilities of the analysisfunctions Cursor, Zoom, and Replay. These functionscan be used with one or more of the primary functionsScope, TrendPlot or Scope Record.

It is possible to combine two or three analysis functions.A typical application using these functions follows:

• First replay the last screens to find the screen ofspecial interest.

• Then zoom in on the signal event.

• Finally, make measurements using the cursors.

Replaying the 100 Most Recent ScopeScreensWhen you are in scope mode, the test tool automaticallystores the 100 most recent screens. When you press theHOLD key or the REPLAY key, the memory contents arefrozen. Use the functions in the REPLAY menu to “go backin time” by stepping through the stored screens to find thescreen of your interest. This feature lets you capture andview signals even if you did not press HOLD.


36

Replaying Step-by-Step

To step through the last scope screens, do the following:

1 From scope mode, open theREPLAY menu.

Observe that the trace is frozenand that REPLAY appears at thetop of the screen (see Figure 21).

2 Step through the previousscreens.

3 Step through the next screens.

Observe that the bottom of the waveform area displaysthe replay bar with a screen number and related timestamp:

Figure 21. Replaying a Waveform

The replay bar represents all 100 stored screens inmemory. The icon represents the picture beingdisplayed on the screen (in this example: SCREEN -84). Ifthe bar is partly white, the memory is not completely filledwith 100 screens.

From this point you can use the zoom and cursorfunctions to study the signal in more detail.

Using Replay, Zoom and CursorsReplaying the 100 Most Recent Scope Screens 4

37

Replaying Continuously

You can also replay the stored screens continuously, likeplaying a video tape.

To replay continuously, do the following:

1 From Scope mode, open theREPLAY menu.

Observe that the trace is frozenand REPLAY appears at the top ofthe screen.

2 Continuously replay the storedscreens in ascending order.

Wait until the screen with the signal event of interestappears.

3 Stop the continuous replay.

Turning Off the Replay Function

4 Turn off REPLAY.

Capturing 100 Intermittents Automatically

When you use the test tool in triggered mode, 100triggered screens are captured. This way you could usePulse Triggering to trigger and capture 100 intermittentglitches or you could use External Triggering to capture100 UPS startups.

By combining the trigger possibilities with the capability ofcapturing 100 screens for later replay, you can leave thetest tool unattended to capture intermittent signalanomalies.

For triggering, see Chapter 5: “Triggering on Waveforms”.


38

Zooming in on a WaveformTo obtain a more detailed view of a waveform, you canzoom in on a waveform using the ZOOM function.

To zoom in on a waveform, do the following:

1 Display the ZOOM key labels.

Observe that the trace is frozen,HOLD appears at the top of thescreen, and the waveform ismagnified.

2 Enlarge (decrease the time/div)or shrink (increase the time/div)the waveform.

3 Scroll. A position bar displays theposition of the zoomed part inrelation to the total waveform.

Tip

Even when the key labels are not displayed atthe bottom of the screen, you can still use thearrow keys to zoom in and out.

Figure 22. Zooming in a Waveform

Observe that the bottom of the waveform area displaysthe zoom ratio, position bar, and time/div (see Figure 22).The zoom range depends on the amount of data samplesstored in memory.

From this point you can use the cursor function for furthermeasurements on the waveform.

6 Highlight the right cursor.

Figure 24. Time Measurement with Cursors

7 Move the right cursor to thedesired position on thewaveform.

The screen shows the time difference between thecursors and the voltage difference between the twomarkers. (See Figure 24.)

8 Turn off the cursors.


42

Using Cursors on a A+B, A-B or A*B Waveform

Cursor measurements on a A*B waveform give a readingin Watts if input A measures (milli)Volts and input Bmeasures (milli)Amperes.

For other cursor measurements on a A+B, A-B or A*Bwaveform no reading will be available if the input A andinput B measurement unit are different.

Making Rise Time Measurements

To measure rise time, do the following:


2 Press to highlight (rise time).Observe that two horizontalcursors are displayed.

3 If only one trace is displayed,select MANUAL or AUTO (thisautomatically does steps 4 to 6).For multiple traces select therequired trace A, B, or M (if amath function is active).

4 Move the upper cursor to 100%of the trace height. A marker isshown at 90%.

5 Highlight the other cursor.

6 Move the lower cursor to 0% ofthe trace height. A marker isshown at 10%.

The reading shows the risetime from 10%-90% of thetrace amplitude.

Chapter 5Triggering on Waveforms

About this Chapter

This chapter provides an introduction to the triggerfunctions of the test tool. Triggering tells the test toolwhen to begin displaying the waveform. You can usefully automatic triggering, take control of one or moremain trigger functions (semi-automatic triggering), or youcan use dedicated trigger functions to capture specialwaveforms.

Following are some typical trigger applications:

• Use the Connect-and-View™ function to have fullautomatic triggering and instant display of virtuallyany waveform.

• If the signal is unstable or has a very low frequency,you can control the trigger level, slope, and triggerdelay for a better view of the signal. (See nextsection.)

• For dedicated applications, use one of the fourmanual trigger functions:

• Edge triggering

• External triggering

• Video triggering

• Pulse Width triggering


44

Setting Trigger Level and SlopeThe Connect-and-View™ function enables hands-offtriggering to display complex unknown signals.

When your test tool is in manual range, do the following:

Perform an auto set. AUTO appearsat the top right of the screen.

Automatic triggering assures a stable display of virtuallyany signal.

From this point, you can take over the basic triggercontrols such as level, slope and delay. To optimizetrigger level and slope manually, do the following:

1 Display the TRIGGER key labels.

2 Trigger on either positive slope ornegative slope of the chosenwaveform.

3 Enable the arrow keys for manualtrigger level adjustment.

Figure 26. Screen with all Trigger Information

4 Adjust the trigger level.

Observe the trigger icon that indicates the triggerposition, trigger level, and slope.

At the bottom of the screen the trigger parameters aredisplayed. (See Figure 26.) For example, means that input A is used as the trigger source with apositive slope.

When no trigger is found, the trigger parameters appearin gray.

Triggering on WaveformsUsing Trigger Delay or Pre-trigger 5

45

Using Trigger Delay or Pre-triggerYou can begin to display the waveform some time beforeor after the trigger point has been detected. Initially, youhave 2 divisions of pre-trigger view (negative delay).

To set the trigger delay, do the following:

5 Hold down to adjust the triggerdelay.

Observe that the trigger icon on the screen moves toshow the new trigger position. When the trigger positionmoves left off of the screen, the trigger icon changes into

to indicate that you have selected a trigger delay.Moving the trigger icon to the right on the display givesyou a pre-trigger view.

In case of a trigger delay, the status at the bottom of thescreen will change. For example:

This means that input A is used as the trigger source witha positive slope. The 500.0 ms indicates the (positive)delay between trigger point and waveform display.

When no trigger is found, the trigger parameters appearin gray.

Figure 27. Trigger Delay or Pre-trigger View

Figure 27 shows an example of a trigger delay of 500 ms(top) and an example of pre-trigger view of 8 divisions(bottom).


46

Automatic Trigger OptionsIn the trigger menu, settings for automatic triggering canbe changed as follows. (See also Chapter 1: “Displayingan Unknown Signal with Connect-and-View”)


Note

The TRIGGER key labels can differ depending onthe latest trigger function used.

2 Open the Trigger Options menu.

3 Open the Automatic Triggermenu.

If the frequency range of the automatic triggering is set to> 15 Hz, the Connect-and-View™ function respondsmore quickly. The response is quicker because the testtool is instructed not to analyze low frequency signalcomponents. However, when you measure frequencieslower than 15 Hz, the test tool must be instructed toanalyze low frequency components for automatictriggering:

4 Select > 1 HZ and return to themeasurement screen.

Triggering on WaveformsTriggering on Edges 5

47

Triggering on EdgesIf the signal is instable or has a very low frequency, useedge triggering to obtain full manual trigger control.

To trigger on rising edges of the input A waveform, do thefollowing:



3 Open the Trigger on Edge menu.

When Free Run is selected, the test tool updates thescreen even if there are no triggers. A trace alwaysappears on the screen.

When On Trigger is selected, the test tool needs atrigger to display a waveform. Use this mode if you wantto update the screen only when valid triggers occur.

When Single Shot is selected, the test tool waits for atrigger. After receiving a trigger, the waveform isdisplayed and the instruments is set to HOLD.

In most cases it is advised to use the Free Run mode:

4 Select Free Run, jump to Noisereject Filter.

5 Set Noise reject Filter to Off.

Observe that the key labels at the bottom of the screenhave adapted to allow further selection of specific edgetrigger settings:


48

Triggering on Noisy Waveforms

To reduce jitter on the screen when triggering on noisywaveforms, you can use a noise rejection filter. Continuefrom step 3 of the previous example as follows:

4 Select On Trigger, jump to Noisereject Filter.

5 Set Noise reject Filter to On.

Observe that the trigger gap has increased. This isindicated by a taller trigger icon .

Making a Single Acquisition

To catch single events, you can perform a single shotacquisition (one-time screen update). To set up the testtool for a single shot of the input A waveform, continuefrom step 3 again:

4 Select Single Shot.

5 Accept the settings.

The word WAITING appears at the top of the screenindicating that the test tool is waiting for a trigger. Assoon as the test tool receives a trigger, the waveform isdisplayed and the instrument is set to hold. This isindicated by the word HOLD at top of the screen.

Triggering on WaveformsTriggering on Edges 5

49

The test tool will now have a screen like Figure 28.

6 Arm the test tool for a new singleshot.

Tip

The test tool stores all single shots in the replaymemory. Use the Replay function to look at allthe stored single shots.

Figure 28. Making a Single Shot Measurement


50

Triggering on External WaveformsUse external triggering when you want to displaywaveforms on inputs A and B while triggering on a thirdsignal. You can choose external triggering with automatictriggering or with edge triggering.

1 Supply a signal to the red and black 4-mmbanana jack inputs. See Figure 29.

In this example you continue from the Trigger on Edgesexample. To choose the external signal as trigger source,continue as follows:

2 Display the TRIGGER (On Edges)key labels.

3 Select Ext (external) edge trigger.

Observe that the key labels at the bottom of the screenhave been adapted to allow selection of two differentexternal trigger levels: 0.12 V and 1.2 V:

52

Triggering on Video Frames

Use FIELD 1 or FIELD 2 to trigger either on the first halfof the frame (odd) or on the second half of the frame(even).

To trigger on the second half of the frame, do thefollowing:

7 Choose FIELD 2.

The signal part of the even field is displayed on thescreen.

Triggering on Video Lines

Use ALL LINES to trigger on all line synchronization pulses(horizontal synchronization).

7 Choose ALL LINES.

The signal of one line is displayed on the screen. Thescreen is updated with the signal of the next lineimmediately after the test tool triggers on the horizontalsynchronization pulse.

To view a specific video line in more detail, you can selectthe line number. For example, to measure on video line123, continue from step 5 as follows:

7 Enable video line selection.

8 Select number 123.

The signal of line 123 is displayed on the screen.Observe that the status line now also shows the selectedline number. The screen is continuously updated with thesignal of line 123.

Triggering on WaveformsTriggering on Pulses 5

53

Triggering on PulsesUse pulse width triggering to isolate and display specificpulses that you can qualify by time, such as glitches,missing pulses, bursts or signal dropouts.

Detecting Narrow Pulses

To set the test tool to trigger on narrow positive pulsesshorter than 5 ms, do the following:

1 Apply a video signal to the red input A.



4 Select Pulse Width on A... toopen the Trigger on PulseWidth menu.

5 Select the positive pulse icon,then jump to Condition.

6 Select <t, then jump to Update.

7 Select On Trigger.

The test tool is now prepared to trigger on narrow pulsesonly. Observe that the trigger key labels at the bottom ofthe screen have been adapted to set the pulseconditions:


54

To set the pulse width to 5 ms, do the following:

7 Enable the arrow keys to adjustthe pulse width.

8 Select 5 ms.

All narrow positive pulses shorter than 5 ms are nowdisplayed on the screen. (See Figure 31.)

Tip

The test tool stores all triggered screens in thereplay memory. For example, if you setup yourtriggering for glitches, you can capture 100glitches with time stamps. Use the REPLAY key tolook at all the stored glitches.

Using the Independently FloatingIsolated InputsYou can use the independently floating isolated inputs tomeasure signals that are independently floating fromeach other.

Independently floating isolated inputs offer additionalsafety and measurement capabilities compared to inputswith common references or grounds.

Measuring Using Independently FloatingIsolated Inputs

The test tool has independently floating isolated inputs.Each input section (A, B, External Trigger / DMM) has itsown signal input and its own reference input. Thereference input of each input section is electricallyisolated from the reference inputs of the other inputsections. The isolated input architecture makes the testtool about as versatile as having three independentinstruments. The advantages of having independentlyfloating isolated inputs are:

• It allows simultaneous measurement ofindependently floating signals.

• Additional safety. Since the commons are not directlyconnected, the chance of causing short circuit whenmeasuring multiple signals is greatly reduced.

• Additional safety. When measuring in systems withmultiple grounds, the ground currents induced arekept to a minimum.

Because the references are not connected togetherinside the test tool, each reference of the used inputsmust be connected to a reference voltage.

Independently floating isolated inputs are still coupled byparasitic capacitance. This can occur between the inputreferences and the environment, and between the inputreferences mutually (see Figure 44). For this reason, youshould connect the references to a system ground oranother stable voltage. If the reference of an input isconnected to a high speed and / or high voltage signal,you should be aware of parasitic capacitance.(See Figures 45, 46, 47 and 48.)

1 Turn the test tool off.

2 Press and hold.

3 Press and release.

The test tool turns on, and you should hear a doublebeep, indicating the reset was successful.

4 Release.

Suppressing Key Labels and Menu’sYou can hide a menu or key label at any time:

Hide any key label or menu.

To display menus or key labels, press one of the yellowmenu keys, e.g. the SCOPE key.

TipsChanging the Information Language 7

71

Changing the Information LanguageDuring operation of the test tool, messages may appearat the bottom of the screen. You can select the languagein which these messages are displayed. The combinationof selectable languages (one or more) depends on theversion ordered.

In this example you can select English or French . Tochange the language from English to French, do thefollowing:

1 Display the USER key labels.

2 Open the Language Selectmenu.

3 Highlight FRENCH.

4 Accept French as the language.

Adjusting the Contrast and BrightnessAfter power-up, the screen has a bright display. To adjustthe contrast and backlight brightness, do the following:


2 Enable the arrow keys for manualcontrast and backlightadjustment.

3 Adjust the contrast of the screen.

4 Change the backlight.

NoteThe new contrast and brightness are stored untila new adjustment is made.

To save battery power, the test tool is in economicbrightness mode when operated on the battery. The highbrightness intensity increases when you connect thepower adapter.

NoteUsing dimmed light lengthens maximum batterypower operation by about one hour.


72

Changing Date and TimeThe test tool has a date and time clock. For example, tochange the date to 19 April, 1999, do the following:



3 Open Date Adjust menu.

4 Choose 1999, jump to Month.

5 Choose 04, jump to Day.

6 Choose 19, jump to Format.

7 Choose DD/MM/YY, accept thenew date.

You can change the time in a similar way by opening theTime Adjust menu (steps 2 and 3.)

TipsSaving Battery Life 7

73

Saving Battery LifeWhen operated on the battery (no battery chargerconnected), the test tool conserves power by shuttingitself down. If you have not pressed a key for at least 30minutes, the test tool turns itself off automatically.

Note

If the power adapter is connected, there is noautomatic power shutdown.

Automatic power shutdown will not occur if TrendPlot orScope Record is on, but the backlight will dim. Recordingwill continue even if the battery is low, and retention ofmemories is not jeopardized.

Setting the Power Down Timer

Initially the power shutdown time is 30 minutes. You canset the power shutdown time to 5 minutes as following:



3 Open the Battery Save Optionsmenu.

4 Select 5 Minutes.


74

Changing the Auto Set OptionsWith the next procedure you can choose how auto setbehaves when you press the AUTO (auto set) key.



3 Open the Auto Set Adjustmenu.

If the frequency range is set to > 15 Hz, the Connect-and-View function responds more quickly. The response isquicker because the test tool is instructed not to analyzelow frequency signal components. However, when youmeasure frequencies lower than 15 Hz, the test tool mustbe instructed to analyze low frequency components forautomatic triggering:

4 Select Signal > 1 Hz, then jumpto Coupling.

With the coupling option you can choose how auto setbehaves. When you press the AUTO (auto set) key, thecoupling can either be set to dc or left unchanged:

5 Select Unchanged.

Note

The auto set option for the signal frequency issimilar to the automatic trigger option for thesignal frequency. (See Chapter 5: “AutomaticTrigger Options”). However, the auto set optiondetermines the behavior of the auto set functionand shows only effect when you press the autoset key.

This chapter covers basic maintenance procedures thatcan be performed by the user. For complete service,disassembly, repair, and calibration information, see theService Manual. You will find the part number of theService Manual in the section “Parts and Accessories” inthis chapter.

Cleaning the Test ToolClean the test tool with a damp cloth and a mild soap. Donot use abrasives, solvents, or alcohol. These maydamage the text on the test tool.

Storing the Test ToolIf you are storing the test tool for an extended period oftime, charge the NiMH (Nickel-Metal Hydride) batteriesbefore storing.


76

Charging the BatteriesAt delivery, the NiMH batteries may be empty and mustbe charged for 4 hours (with the test tool turned off) toreach full charge. When fully charged, the batteriesprovide 4 hours of use.

When battery power is used, the battery indicator at thetop of the screen informs you about the condition of thebatteries. The battery symbols are: . Thesymbol indicates that there are typically five minutesof operating time left.

To charge the batteries and power the instrument,connect the battery charger as shown in Figure 49. Tocharge the batteries more quickly, turn off the test tool.

Caution

To avoid overheating of the batteries duringcharging, do not exceed the allowableambient temperature given in thespecifications.

Note

No damage will occur if the charger is connectedfor long periods, e.g., during the weekend. Theinstrument then automatically switches to tricklecharging.

Figure 49. Charging the Batteries

Maintaining the Test ToolExtending Battery Operation Time 8

77

Extending Battery Operation TimeTypically, NiMH batteries always meet the specifiedoperating time. However, if the batteries have beenextremely discharged (for example, when empty batterieswere stored for a long period) it is possible that thebattery condition has deteriorated.

To keep the batteries in optimal condition, observe thefollowing guidelines:

• Operate the test tool on batteries until the symbol appears at the bottom of the screen. Thisindicates that the battery level is low and that theNiMH batteries need to be recharged.

• To obtain optimal battery condition again, you canrefresh the batteries. During a battery refresh, thebatteries will be fully discharged and charged again.A complete refresh cycle takes about 12 hours andshould be done about four times a year. You cancheck the latest battery refresh date. See section“Displaying Calibration Information”.

To refresh the battery, make sure that the test tool is linepowered and proceed as follows:



A message appears asking whether you want to start therefresh cycle now.

3 Start the refresh cycle.

Do not disconnect the battery charger during therefresh cycle. This will interrupt the refresh cycle.

Note

After starting the refresh cycle, the screen will beblack.


78

Replacing the NiMH Battery Pack BP190Usually it should not be necessary to replace the batterypack. However, if replacement is needed, this should bedone by qualified personnel only. Contact your nearestFluke center for more information.

Calibrating the Voltage ProbesTo meet full user specifications, you need to adjust thered and gray voltage probes for optimal response. Thecalibration consists of a high frequency adjustment and adc calibration for 10:1 probes. The dc calibration is notpossible for 100:1 probes.

This example shows how to calibrate the 10:1 voltageprobes:

1 Display the input A key labels.

2 Open the Probe on A menu.

3 Select Voltage, then jump toAttenuation.

Figure 50. Adjusting Voltage Probes

If the 10:1 option is already selected, proceed with step 5.

4 Select 10:1, then return.

Maintaining the Test ToolCalibrating the Voltage Probes 8

79

Repeat steps 2 and 3 and proceed as follows:

5 Select Probe Cal with the arrowkeys, then accept.

A message appears asking you whether to start the 10:1probe calibration.

6 Start the probe calibration.

A message appears telling you how to connect the probe.Connect the red 10:1 voltage probe from the red input Ajack to the red banana jack. Connect the reference leadto the black banana jack. (See Figure 50.)

7 Adjust the trimmer screw in theprobe housing until a pure squarewave is displayed.

8 Continue with DC calibration.Automatic DC calibration is onlypossible for 10:1 voltage probes.

The test tool automatically calibrates itself to the probe.During calibration you should not touch the probe. Amessage indicates when the DC calibration hascompleted successfully.

9 Return.

Repeat the procedure for the gray 10:1 voltage probe.Connect the grey 10:1 voltage probe from the grey inputB jack to the red banana jack. Connect the reference leadto the black banana jack.

Note

When using 100:1 voltage probes, choose 100:1attenuation to perform a HF adjustment.Automatic dc calibration is not possible with thisprobe type.


80

Displaying Calibration InformationYou can display version number and calibration date:


2 Open the Version & Calibrationmenu.

The screen gives you information about the modelnumber with software version, the calibration number withlatest calibration date, and the latest battery refresh date.

3 Return.

Recalibration must be carried out by qualified personnel.Contact your local Fluke representative for recalibration.
