M9392A Troubleshooting
M9392A Troubleshooting
Communications
If you are unable to communicate with the M9392A, verify that the following installations are correct:
l
Agilent IO Libraries Suite
l
M9392A SFP
l
Module and chassis drivers
l
System Interface Card, cable and PC PXI card connections
l
If no modules are visible in the SFP "Connect to Instrument" dialog or in Agilent Connection Expert, restart
your PC or embedded controller to establish these connections.
Modular Instrument Troubleshooting Overview
Between the low frequency path (through the M9351A) and the high frequency path (through the M9361A) there
are three common modules and one unique to the path (See "
).
To troubleshoot a modular instrument problem, first:
1. Check cabling.
2. Check the front panel Status LEDs.
3. Check the M9392A SFP (soft front panel) Status Tab and Self Tests.
4. Perform a modular instrument level operational check.
5. If a suspect module still can’t be identified, determine the frequency range at which the problem occurs and

to identify the most likely module(s) and then perform
the module operational checks found in the Startup Guides.
Cables
l
Start by verifying ALL cables are properly connected and SMA connectors are torqued to 8 Lb-In (0.904 Nm).
l

for instrument-level cabling. M9392A
cable connections are also available from the M9392A SFP, by selecting
Configure > Cable Configuration.
Modular Instrument Level Troubleshooting
Modular instrument level troubleshooting can be used to identify possible cabling errors and a limited number of
module performance issues without compromising the Field Calibration. The modular instrument level trou-
bleshooting procedure starts by looking at the front panel LEDs, progresses to the modular instrument level soft
front panel (SFP) interface and then offers a limited set of operational checks aimed at identifying a suspect mod-
ule. Once a suspect module is identified it becomes necessary to remove cables (compromising the Field Cal-
ibration) to perform the module operational check to verify the module's performance. At the modular instrument
level you are encouraged to modify frequency points and power levels to cover suspect problem areas.
Configuration/Setups
l
Verify all module interconnect cable routings, and SMA connectors are torqued to 8 Lb-In (0.904 Nm).
l
No RF signal is routed into the Agilent M9360A PXI Attenuator/Preselector RF IN connector.
l
No 10 MHz reference signal is routed into the Agilent M9302A PXI Local Oscillator.
l
The M9392A SFP (soft front panel) is active.
l
SFP Measurement Frequency is set to 3 GHz (default condition).
