70429AK95 Operation

OperationThis User’s and Service Guide Supplement contains information necessary for use of the 70429AK95 Frequency Divider. The 70429AK95 is an accessory used in conjunction with the Agilent E5505A Phase Noise System or an E8257D/E8267D Synthesized Signal Generator to improve the phase noise performance. With the input connected to the RF output of the signal generator, the 70429AK95 divides the frequency down to a lower frequency based on the divide number determined by configuring the appropriate switches A1, A2, or A3, B1, B2 or B3. The divided RF output frequency may have less phase noise than it would if it were output directly from the signal generator.

General Information

The 70429AK95 Divider Accessory accepts RF frequencies in the 25.6 MHz to 10 GHz frequency range at a minimum level of +3 dBm, but not greater than +7 dBm. In order to provide the best possible signal to noise ratio at the input to the divider, it is recommended that the signal generator output level be set to +16 dBm and a 10 dB passive attenuator be placed between the signal generator output and the divider input. If the signal generator can not be set to +16 dBm, use a lower output power and a correspondingly smaller attenuator value such that the power at the divider input is approximately +6 dBm. The output signal will be at a frequency equal to the input frequency, divided by a divide number set by configuring the appropriate switches (see Table 2) at a level of +5 dBm nominal (RF Out − and RF Out + Ports) and +15 dBm nominal (1.6 GHz amplifier RF Out Port).

The 70429AK95 has 2 independent dividers; A and B. The output of divider A is connected internally to the input of divider B. Each divider can be programmed independently to divide by 1,2,4,8 or 16, for a maximum division ratio of 256.

Making the 10 MHz Measurement

Step 1. Left-click on Measure and verify that the Pause at Connect Diagram is checked. If not, select it.

Step 2. Left-click on Measurement in the drop-down menu and select New Measurement.

Step 3. Click Yes in the Do you want to perform a new Calibration and Measurement? popup. The Agilent E5500 Instrument Connections window will appear.

Step 4. On the 70427A rear panel, remove the jumper from the 10 MHz Oven Out to 10 MHz In. Refer to Figure 6 on page 20.

Step 5. Connect the 10 MHz Oven Out on the 70427A rear panel to the Signal Input on the 70420A.

Step 6. Set E8257D to 2.56 GHz at +16 dBm. Select RF ON.

Step 7. Select FM/ Phi M on the E8257D. Set FM Dev to 256 Hz. Select FM Source > Ext 1. Verify Ext Coupling, DC.

Step 8. Select More > Ext Impedance > 600 Ohm. Select More > FM ON.

Step 9. Connect E8257D RF Output through a 10 dB attenuator to 70429AK95 RF IN +.

Step 10. Set both divider sections in 70429AK95 to divide by 16.

Step 11. Connect the jumper from 70429AK95 RF OUT+ to 1.6 GHz Amplifier RF IN. Connect the 70420A Amplifier RF OUT to 50 kHz to 1600 MHz Ref Input.

Step 12. Connect 70420A Tune Voltage Output to E8257D Ext 1 Input.

Step 13. Verify that a beat note is present, using an oscilloscope or counter connected to the Monitor port of the 70420A.

Step 14. Select Continue and allow the Phase Noise Measurement to complete.

Step 15. If the E5500 Manual Tune Pause Point dialog box appears, adjust the E8257D frequency in 10 Hz steps until the beat note frequency is at a minimum. The best way to observe this is to use an oscilloscope on the Monitor port of the 70420A. Select Continue.

Step 16. Compare the estimated mean value of the trace with the noise specification line. If the estimated mean value of the trace falls on or below the specification line, the 70429AK95 is regarded as having met the noise specification. A small noise peak near 1 MHz may be above the specification line. This is acceptable as the peak is not due to the 70429AK95 Divider.

Step 17. Print the E5500 Phase Noise Plot.

Step 18. Connect the jumper that was removed from the rear panel of the 70427A in Step 4.

Electrostatic Discharge Protection

Protection against electrostatic discharge (ESD) is essential while removing assemblies from or connecting cables to the network analyzer. Static electricity can build up on your body and can easily damage sensitive internal circuit elements when discharged. Static discharges too small to be felt can cause permanent damage. To prevent damage to the instrument:

• always have a grounded, conductive table mat (9300-0797) in front of your test equipment.

• always wear a grounded wrist strap (9300-1367) with grounding cord (9300-0980), connected to a grounded conductive table mat, having a 1 MΩ resistor in series with it, when handling components and assemblies or when making connections.

• always wear a heel strap (9300-1126) when working in an area with a conductive floor. If you are uncertain about the conductivity of your floor, wear a heel strap.

• always ground yourself before you clean, inspect, or make a connection to a static-sensitive device or test port. You can, for example, grasp the grounded outer shell of the test port or cable connector briefly.

• always ground the center conductor of a test cable before making a connection to the analyzer test port or other static-sensitive device. This can be done as follows:

1. Connect a short (from your calibration kit) to one end of the cable to short the center conductor to the outer conductor.

2. While wearing a grounded wrist strap, grasp the outer shell of the cable connector.

3. Connect the other end of the cable to the test port and remove the short from the cable.

Figure 7 shows a typical ESD protection setup using a grounded mat and wrist strap.
