M9392A Troubleshooting
Possible Self Test Failures
The chassis must be turned off when installing or removing modules.
1. Power supply failure:
a. If a voltage failure is reported, check the voltages on the other modules, using the SFP Status tab.
Since power supply failures can be related to chassis or module failures, the first step is to check for
a defective module.
b. If the problem is limited to the one module on the SFP Status tab, turn power off and move that mod-
ule to a different slot (cable connections are not required). Turn power back on and check again.
i. Replace the module if the voltage is still bad.
ii. If the voltage is good, after moving the module to a different slot, check the chassis power supply.
c. If more than one module voltage is bad, there is a possibility the chassis is bad or one of the modules
may be pulling down the power supply. Start by turning power off, removing one module at a time
and turning power on.
d. Continue removing one module at a time until only one module remains.
i. If the voltage is good after removing a module, reinstall the other modules.
ii. If the voltage is still good after reinstalling the other modules, the module that was pulling the
power supply down needs to be repaired.
iii. If the voltage is bad after reinstalling the other modules troubleshoot the chassis.
iv. If the voltage is still bad after removing all but the last module, remove the last module and rein-
stall one of the modules that was previously removed.
v. If the voltage is still bad, troubleshoot the chassis.
2. Temperature failure:
a. Temperature failures indicate over temperature.
i. Verify that blank panels have been installed in any open slot on the chassis.
ii. Make sure the chassis air intake and outlets are open and not blocked.
iii. Verify the chassis fans are working and fan speed to is set to Auto.
iv. Verify the ambient temperature is within the instrument operating range (0° C to 50° C).
v. If a single module over-temperature has not been resolved, the module is most likely starting to
fail and should be serviced.
3. M9351A - :LO Sense:
a. LO Sense indicates the M9351A is not able to detect the LO IN signal. If you get an LO Sense indi-
cation, check:
Removing the following cables negates the Field Calibration.
i. A5 cable connections between the M9351A LO IN and the M9360A Attenuator/Preselector LO
1 OUT.
ii. A1 cable, M9302A LO OUT to M9360A LO IN
