Operational Check
This operational check procedure is used for high-level troubleshooting – a rough diagnostic to ascer-
tain if the module is functioning properly. You do not have to conduct the operational check if you
conduct the
Performance Verification Tests
(see page
).
Requirements for Operational Check
The Agilent M9360A PXI Attenuator/Preselector operational check measures the signal paths from the RF IN
connector to the RF 1 OUT and RF 2 OUT connectors. The following process demonstrates that all associated
switches, connectors, cables and circuitry are operational. The signal paths from the LO IN connector to the LO 1
OUT and LO 2 OUT connectors are also measured.
Required Hardware
To demonstrate that the module works properly requires external equipment. This includes a precision microwave
source and a power meter You will not be using the module interconnect cables, so some high-quality flexible 3.5
mm cables will be required, plus adaptors to connect the PSG (precision signal generator) and power sensors to
3.5 mm connectors. Please refer to the following table for recommended hardware.

M9360A Operational Check Procedure
To use a single power meter in place of two power meters and sensors, characterize the PSG output
power at the different frequencies and then connect the PSG output directly to the M9360A RF IN.
Connect the power sensor to the outputs listed in the procedure below.
