M9403A and M9404A M9403A and M9404A Operational Check Procedure
Equipment Test Configuration Option III (Signal Source & Spectrum Analyzer)
1. Adjust the Signal Source Stimulus Power for the M9403A-H02 to -30 dBm, or -10 dBm for
the M9403A-H01.
2. Set the CW Frequency Sweep to 50 MHz.
3. Set the Center Frequency to 50 MHz on the Spectrum Analyzer respectively.
4. Connect the Stimulus Source to M9403A Access Port.
5. Connect the Spectrum Analyzer to M9404A Access Port.
NOTE Depending on your instrument’s power handling capability it may be necessary to
use a 20 dB attenuator to protect the instrument.
6. Connect optical ports between M9403A and M9404A using an optical cable.
7. Measure the Power and compare Link Loss (Pmeasured - Pstimulus).
8. Set the Signal Source to a CW Frequency of 10 GHz.
9. Repeat
step 5 thru step 7 .
10.Set the Signal Source to a CW Frequency of 26.5 MHz.
11.Repeat
step 5 thru step 7 .
12.Set the Signal Source to a CW Frequency of 50 GHz.
13.Compare the Link Loss to
Table 3 on page 5 .
NOTE For Option H02 on the M9403A or M9404A you should expect to see a 30 dB
improvement over the Link Loss. Return Loss may be different as well.
