Operation 2-11

Operator's Check

Description

The operator's check consists of two softkey-initiated tests: Port 1 Op Chk

and Port 2 Op Chk.

A short is connected to port 1 (port 2, port 3) to re ect all the source energyback into the analyzer for an S11 (S22) measurement.

The �rst part of Port 1, Op Chk checks the repeatability of the transferswitch. An S11 measurement is stored in memory and the switch is toggledto port 3 and then back to port 1 where another S11 measurement is made.The di�erence between the memory trace and the second trace is switchrepeatability.

The remaining parts of both tests exercise the internal attenuator in 5 dBsteps over a 55 dB range.

The resulting measurements must be within a limit testing window to passthe test. The window size is based on source and receiver speci�cations.

The operator's check determines the following:

The source is phase locked across the entire frequency range.

All three samplers are functioning properly.

All transfer switches and receiver switches are operational.

The attenuator steps 5 dB at a time.

System Verification and Performance Tests

There are two ways to con�rm that the HP 8753E Option H39 networkanalyzer is able to make measurements as speci�ed by Hewlett-Packard. Bothways are described in this chapter.

The �rst way is through the system veri�cation procedure. With systemveri�cation, the performance of the network analyzer is con�rmed as acomplete measurement system. The network analyzer is used to measure thetraceable behavior of test devices that are part of a veri�cation kit. All themeasurement uncertainties of the network analyzer, taken as a measurementsystem, have been accounted for in the serialized data disk shipped with theveri�cation kit.

The second way to con�rm the speci�ed performance of the network analyzer isby using the series of performance tests described in this chapter. Successfulcompletion of an individual test con�rms the speci�ed performance of thespeci�c subsystem tested, such as the source or receiver. Successful completionof the whole series of performance tests con�rms the speci�ed performance ofthe network analyzer as a complete measurement system.

For a complete description of the veri�cation and performance test processrefer to the HP 8753E Service Guide.

System Verification and Performance Tests 2-1

How to Test the Performance of Your Analyzer

To obtain the same quality of performance testing that Hewlett-Packard hasadministered at the factory, you must perform one of the following:

the system veri�cation procedure

OR

all of the performance test procedures.

This quality of performance testing guarantees that the analyzer is performingwithin all of the published speci�cations. Hewlett-Packard will issue aCerti�cate of Calibration for your analyzer if the following conditions are met:

1. The performance veri�cation tests are performed by personnel quali�ed byHewlett-Packard.

2. Your analyzer passes all the performed tests.

3. The equipment and standards that you used to perform the tests aretraceable to a national standards institute.

Note If you have a particular type of measurement application thatdoes not use all of the analyzer's measurement capabilities, youmay ask your local Hewlett-Packard service center for a subsetof speci�cations that you want veri�ed. However, this doescreate a potential for making incorrect measurements, if youuse a di�erent application than what was speci�ed.

2-2 System Verification and Performance Tests

General Instrument Setup Information

In the veri�cation procedure, the HP 8753E Option H39 is set up usingType-N (m) to APC-7 adapters. The adapters are installed on ports 1 and 3.Cables are then connected to the adapters. This setup is used throughout theveri�cation procedure. Calibration of the instrument is done with the adaptersand cables attached. If the cables are removed, the calibration will be a�ectedand the performance of the instrument will be invalid. All connections toports 1 and 3 are done at the open end of the cable. The analyzer will be setup to use the turn-on and preset default ports (port 1 and port 3). Systemveri�cation of the HP 8753E Option H39 requires less setup, by leaving theadapters and cables on the analyzer, and utilizing the default settings.

Note Once calibration is completed with the adapters and cablesattached to the analyzer, the adapters and cables shouldremain on the analyzer until all of the veri�cation procedurehas been completed. If the adapters or cables are removed thecalibration is a�ected and the performance of the instrumentwill be invalid.

System Verification Cycle and Kit Recertification

Hewlett-Packard recommends that you verify your network analyzermeasurement system every six months. Hewlett-Packard also suggests that youget your veri�cation kit recerti�ed annually. Refer to the HP 85029B 7-mm

Veri�cation Kit Operating and Service Manual for more information.

Check to see how the veri�cation kit's oppy disk is labeled:

If your veri�cation disk is labeled HP 8753D Verification Data Disk, orHP 8753D & HP 8753E Verification Data Disk, you may proceed with thesystem veri�cation.

If your veri�cation disk is not labeled as indicated above, you may sendyour HP 85029B 7-mm veri�cation kit to the nearest service center forrecerti�cation, which includes a data disk that you can use with theHP 8753E.

6. Test Port Input Noise Floor Level

Perform this test to determine the HP 8753E port 1, port 2, and port 3 noise oor levels at the input test ports.

Note Port 2 is separated into eight di�erent measurements, whileports 1 and 3 are separated into four measurements (two IFbandwidths per each frequency range, with two frequencyranges being measured). Port 2 is separated into channel Aand channel B. Channel A is the path from port 2 to theA sampler and channel B is the path from port 2 to the Bsampler. Each channel path (A or B) is then separated intofour measurements (two IF bandwidths per each frequencyrange, with two frequency ranges being measured). This willtotal the eight di�erent measurements being done for port 2.

13. Test Port Receiver Magnitude Dynamic Accuracy

Note The HP 8496A step attenuator (Option 001, H18) comes with aspecial calibration that supports the measurement uncertaintiesexpressed in the test record for this performance test.

The special calibration consists of two measurements. The �rstis a measurement of the attenuation at each step. The datareported for this measurement have the following uncertainties:

�0.006 dB from 0 to 40 dB

�0.015 dB from >40 to 80 dB

�0.025 dB from >80 to 90 dB

�0.05 dB >90 dB

The second calibration measurement characterizes matchstability between attenuator settings for each attenuatorport. The vector di�erence of S11 or (S22) between thereference attenuation step and all the other steps is measured.The magnitude of this di�erence is certi�ed to be <0.0316(>30 dB).

Note The HP 8496A used for this test will have known attenuatorerrors for attenuations up to 100 dB using a test frequency of30 MHz. The attenuation used as a reference is 0 dB. If theavailable calibration data are not expressed as attenuationerrors, it can be converted to such a form by the followingequation: (actual attenuation) � (expected attenuation) =attenuator error. Actual attenuation values that are greaterthan the expected attenuation values will result in positiveerrors. Actual attenuation values that are less than theexpected attenuation values will result in negative errors.

Initial Calculations

1. Fill in the attenuator error values (referenced to 0 dB attenuation)in Table 2-1 by referring to the calibration data for the HP 8496Astep-attenuator. Refer to the note on the previous page.

2. Find the column in the HP 8496A attenuation error table that pertains tothe attenuation errors for 30 MHz.

3. Starting with the \10 dB" step in this column, write down the value in thecorresponding space in Table 2-1 for column \B." This value should beplaced in the row for the 10 dB HP 8496A setting.

4. Continue transferring the remaining values of the HP 8496A attenuationerrors to column \B" in Table 2-1.

5. In Table 2-1, transfer the 10 dB error value located within the parenthesisin column \B" to each space in column \C."

6. The values in column \D" result from changing the reference attenuation ofthe calibration data of the HP 8496A to 10 dB.

Calculate the attenuation error values for this column by subtracting thevalues in column \C" from the values in column \B" (B � C = D).

7. The values in column \F" result from correcting the expected measurementvalue by the amount of attenuator error.

Calculate the values in this column by subtracting the values in column\D" from the values in column \E" (E � D = F).

8. Transfer the values from column \F" in Table 2-1 to column \F" on the\Performance Test Record," for both test ports.

Theory of Operation and Troubleshooting

This chapter provides a basic theory of operation and troubleshootingguide for the HP 8753E Option H39. This information is intended to beused as a guide in �nding and remedying possible problems that could beexperienced with the HP 8753E Option H39. Component locations, cablediagrams, and other aides are supplied in this section of the service guide.If the information provided is not enough to remedy the problem, referto your HP 8753E User's and Service Guide. It is recommended that allservice be done in an ESD safe environment. Read the safety informationin the analyzer's user and service guide before doing any work on theHP 8753E Option H39.

Theory of Operation and Troubleshooting 3-1

Theory of Operation

Three-Port Test Set

The HP 8753E Option H39 is a three-port signal-separation test set thatseparates any given two ports to the A and B receiver channel samplers. Referto Figure 3-12 and Figure 3-13 for the HP 8753E Option H39 componentlocations and RF paths.

The HP 8753E Option H39 adds a third test port to the HP 8753E test set.Three test ports allow measurement applications for three-port devices with theability to make S-parameter measurements between any two test ports. Thisoption adds four additional solid-state switches, RF cabling to redirect the RFsource, and the A and B channel receiver inputs.

Test port 1 is con�gured to operate as in a normal instrument, while ports 2and 3 are switched in and out by one additional solid-state switch. The A andB channel receiver inputs are redirected through a matrix of three solid-stateswitches that connect directly to the coupled arm of each test port coupler.Test ports are controlled by the internal TTL I/O signals. Test ports areType-N.

A network analyzer with this option will have slightly degraded output powerlevels, accuracy, and dynamic range. Refer to Chapter 3, \Speci�cations," formore details.

Note With the Option H39, test port bias can only be supplied toport 1 from the port 1 bias connector on the rear panel. Theport 2 bias connector on the rear panel is not connected.

Test port 1 and test port 3 are the instrument's default ports.On preset, or when power is turned on, port 1 and port 3 areactive.

3-2 Theory of Operation and Troubleshooting

Test Port Couplers

The analyzer's test port couplers are used to separate signals incident to,re ected from, and transmitted by the device under test. Each test portcoupler has a coupling factor of 16 dB.

LED Front Panel

The front panel LEDs indicate whether the test port is the incident port, thereceiver port, or the inactive port. The test port LED that is the brightestis the incident port. The test port LED that is dim is the receiver port. Thetest port where the LED is o� is the inactive port. The inactive test port iswhere no signal separation is taking place. When the analyzer's source poweris directed to test port 1 when performing a forward transmission or re ectionmeasurements, the LED is bright. If the test port 2 LED, is dim, this is thereceiver port. Port 3 LED is o� in this condition and is inactive. Only twoLEDs are on at any given time.

Transfer Switch S0

The A3 source output is directed to either the analyzer's test port 1 or testports 2 and 3 receiver switch via a low-loss solid-state switch. With this switch,all four S-parameters can be measured continuously. In addition, the transferswitch provides termination for the receiver test port in order to minimize thecrosstalk between source and receiver sampler.

Test Port 2 and 3 Source Switch S1

S1 is the source separator for test ports 2 and 3. In addition, the test ports2 and 3 transfer switch provides termination for the inactive test port tominimize the crosstalk to either source and receiver sampler and provide a loadmatch to the device under test.


A Sampler Receiver Switch S2

Provides re ected or transmitted measured signals from test port 1 or 2 to theA channel sampler.

B Sampler Receiver Switch S3

Provides re ected or transmitted measured signals from test port 2 or 3 to theB channel sampler.

Port 2 Receiver Switch S4

Provides re ect or transmitted signals from test port 2 to be directed to eitherA or B channel samplers.

Test Set Interface

The test set interface board provides biasing for active devices under test withan external dc voltage. Only test port 1 can provide bias. Bias supplied to testport 1 is applied directly to the center conductor pin. In addition, the test setinterface board provides the drive signals for all internal solid-state switches.


Troubleshooting

This procedure only covers the Option H39 area of the HP 8753EOption H39. For information concerning the analyzer, refer to yourHP 8753E User's and Service Guide.

Note Test Port 1 will measure 0 dBm, test ports 2 and 3 willmeasure �2 dBm.


No RF Source at All Test Ports

The A3 source may be the problem. Refer to the HP 8753E Service Guide,section 4, for source problems. If the A3 source is veri�ed and working, thenproceed to the \No RF Source at test port 1" section, below.

No RF Source at Test Port 1

Check the bias connection to the switch S0 (see Figure 3-13) and the J3connection (see Figure 3-17) on the test set interface board. If the biasconnector is loose, reconnect it. If the bias connector is �rmly in place inthe J3 connector, check the bias voltages on the switch S0 (+0.62 Vdc and+16.3 Vdc). The center bias pin on S0 should be approximately 22 V.

1. Use the tab on the side of one of the switches (S0, S1, S2) as the groundconnection point.

The voltage on bias pins 1 and 2 should alternate between +0.62 Vdcand +16.3 Vdc, when toggled (�6� �x1� to �5� �x1�). If the bias voltagechanges state, but there is still no RF at the test port 1, the transferswitch S4 may need to be replaced. If the bias voltage remains thesame, then check the LEDs to make sure the source test port is beingredirected. When the instrument is toggled from ports 3 to 2 and 2 to 1,the bright LED should change from port 3 to port 2. If the LEDs areworking on ports 3 to 2, and 1 to 2, and the bias voltage is still incorrecton switch S4, disconnect J14 (see Figure 3-17) and check the biasvoltage on S3 (see Figure 3-13) and toggle the instrument between theNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNTESTSET I/O REV �6� �x1� and

does not change, replace test set interface board. If the bias voltage doeschange, replace S4.

If A channel response is degraded, and a bad load match exists on port 2,this may indicate a bad test port coupler. To check the load match onport 1, follow the instructions in the veri�cation procedure in Chapter2 of this Service Guide. Replace the test port 1 coupler if port 1 loadmatch fails.

If no response is seen for channel B, check the bias connection to switch S4 (seeFigure 3-13), and the J14 connection (see Figure 3-17) on the test set interfaceboard. If bias connector is loose, reconnect it. If the bias connector is �rmlyin place in the J14 connector, check the bias voltages on switch S4 (+0.62 Vdcand +16.3 Vdc).

The voltage on the bias pins 1 and 2 should alternate between +0.62 Vdcand +16.3 Vdc, when the instrument is toggled from (�6� �x1� to �5� �x1�).If the bias voltage changes state, but there is still no RF at the test port1, the transfer switch S4 may need to be replaced. If the bias voltageremains the same, check the LEDs to make sure the source test port isbeing redirected. When the instrument is toggled from ports 1 to 2 and2 to 3, the bright LED will change from port 1 to port 2. If the LEDsare working on ports 1 to 2, and 2 to 3, and the bias is still incorrect onswitch S4, disconnect the J14 connector (see Figure 3-17), check the biasvoltage at S3 (see Figure 3-13), and toggle the instrument between theNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNTESTSET I/O FWD �6� �x1� and
