M9405A Operational Check Procedure
The operational check measures the signal paths from the RF Input of the M9405A module. The following
procedure verifies that the connectors and circuitry are operating correctly.
CAUTION
Do not exceed the maximum input power level of +20 dBm.
Equipment Required
To demonstrate that the module works properly requires external equipment with operating frequency
range of 10 MHz to 26.5 or 50 GHz. This includes a network analyzer, or optionally, a signal source and
power meter or spectrum analyzer.

Equipment Test Configuration Option I (Network Analyzer)
1. Adjust the Network Analyzer Stimulus Power for the M9405A to −30 dBm.
2. Set the Frequency Sweep from 10 MHz to 26.5 or 50 GHz depending on Options F26 or F50.
3. Perform a 2-Port Network Analyzer calibration (normalization response is adequate).
4. Connect the Stimulus Source (Network Analyzer Port 1) to the M9405A RF Input Port.
5. Connect Port 2 of the Network Analyzer to the M9405A RF Output 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. Measure the Return Loss (S11 & S22) and Gain (S21). Compare it to the typical performance in
on page
