High-Level Diagnostic Tools, Processes and References
7. Connect the PSG RF OUTPUT to
a. The power splitter input.
b. Connect a power sensor to one power splitter output.
c. Connect the other power splitter output to the M9360A RF IN.
d. Connect the second power sensor to RF 2 OUT.
8. Step the PSG frequency from 3 GHz to 26.5 GHz in 500 - MHz steps
9. The delta between the power meter readings should be ≤ 7 dB maximum loss between RF IN and RF 2 OUT
at each frequency.
10. Using the M9360A SFP, under Custom Settings:
a. Increase the attenuation to 10 dB.
b. The power meter reading on the RF 2 OUT connector should drop approximately 10 dBm.
c. Continue increasing attenuation in 10 dB steps to 20 dB, and 30 dB. Verify that the RF 2 OUT power
decreased approximately 10 dB with each step.
11. Deselect Custom Settings (click inside the small square and the check mark disappears).
12. Under Primary Settings:
a. Set the Input Frequency to 3 GHz.
b. Select Preselector Enabled (click inside the small square and a check mark appears).
c. Set the Input Level to -40 dBm (this sets the Preselector internal attenuator to 0 dB).
13. Step the PSG frequency from 3 GHz, to 26.5 GHz in 500 - MHz steps and set the Input Frequency to the same
frequency as the PSG. If the frequency is in italics, press the keyboard return key.
a. The delta between the power meter readings should be ≤ 12 dB maximum loss between RF In and
RF 2 OUT at each frequency.
b. Deactivate Preselector Enabled (click inside the small square and the check mark disappears).
14. Under Primary Settings:
a. Set the Input Frequency to 2 GHz.
b. Move the power sensor from RF 2 OUT to RF 1 OUT.
c. Set the PSG to 0 dBm, 100 MHz, RF ON, Modulation OFF.
d. Step the frequency from 100 MHz to 3 GHz in 500 - MHz steps.
e. The delta between the power meter readings should be ≤ 2 dB maximum loss between the RF IN and
RF 1 OUT.
15. Under Primary Settings; set the Input Frequency to 5 GHz
16. On the PSG:
a. Set the power to 0 dBm, frequency to 3 GHz, RF- ON, Modulation - Off.
b. Move the cable from the RF IN to LO IN.
c. Move the power sensor from RF 1 OUT to LO 2 OUT.
d. Step the PSG frequency from 3 GHz to 10 GHz in 500 - MHz steps.
e. The delta in power between LO IN and LO 2 OUT should be ≤ 1dB.
