M9380A Troubleshooting
9. Uncheck, “Use External Reference” and remove the cable from the Ref In connector.
10. If the Reference loses lock, the module is defective and should be repaired. See "Return an Instrument for Service"
on page 11 .
100 MHz Out 1 through 5 Connectors
1. Set the signal analyzer reference level to +20 dBm, and the center frequency to 100 MHz.
2. On the SFP, under the Reference tab and under 100 MHz Reference, check Enable Out 1-5.
3. On the SFP, under External, verify that "Use External Reference" is unchecked (disabled.)
4. Connect the RF INPUTon the signal analyzer to the 100 MHz Out 1 connector on the M9300A.
5. The output level should be ≥ 10 dBm.
6. Measure the power out of 100 MHz Out 2 through 5 for ≥ 10 dBm.
7. On the SFP, disable (uncheck) 100 MHz Out 1 through 5.
8. Repeat the measurement of power on 100 MHz Out 1 through 5.
9. The power level should be ~ 20 dB less than measured when the outputs were enabled.
10. If any power level fails (when enabled or disabled) the Reference module needs to be repaired. See "Return an Instru-
ment for Service" on page 11 .
10 MHz Out, 100 MHz BP Out and OCXO Out Connectors
1. On the SFP under the “Reference” tab, find “Miscellaneous”. Select and enable 100 MHz BP, 10 MHz Out, and OCXO
Out.
2. Set the signal analyzer center frequency to 10 MHz, reference level to 20 dBm and span to 1 kHz.
3. Connect the signal analyzer to 10 MHz OCXO Out on the M9300A.
4. Verify that the 10 MHz OCXO power level is ≥ +9 dBm.
5. Connect the signal analyzer to the 10 MHz Out connector and verify that the power is ≥ +7 dBm.
6. Set the signal analyzer center frequency to 100 MHz and the span to 50 kHz.
7. When the 10 MHz Out and OCXO Out controls are Enabled and there is no or low signal present, the module is defect-
ive and needs to be repaired. See "Return an Instrument for Service" on page 11 .
8. Set the signal analyzer center frequency to 100 MHz and the span to 50 kHz.
9. Connect the signal analyzer to the 100 MHz BP Out connector and verify that the power is ≥ +10 dBm.
10. If the power level is low, the module is defective and needs to be repaired. See "Return an Instrument for Service" on
page 11 .
