M9380A Troubleshooting
M9310A PXIe Source Output Troubleshooting
Before proceeding, check the outputs of the M9301A and M9311A (if applicable).
1. Verify that all module interconnect cables are properly connected. See "M9380A Instrument Connections" on page
20 .
2. Set the signal analyzer to
a. Reference level: 30 dBm
b. Span: 1 MHz
c. Reference Bandwidth and Resolution Bandwidth set to "Auto"
3. Using the SFP, set the Amplitude to +10 dBm for a standard instrument or +19 dBm for a high power instrument
(Option 1EA), turn RF On, and ALC On.
4. Connect the M9310A RF Out to the signal analyzer RF In.
5. Using the list below, set the SFP and signal analyzer frequencies and verify the power levels. A Standard M9310A
should have on output of +10 dBm. An M9310A with High Output Power Option 1EA should have an output of +19
dBm for frequencies up to 2.5 GHz, and +18 dBm for frequencies above 2.5 GHz.
Cable loss must be considered, when determining the results.
