2.
Power on your system and run the MAX configuration and self-test procedures.

What Should I Do if the NI 5624R IF Digitizer Module Does Not
Phase-Lock to the NI 5653 LO Source Module?
If the IF digitizer module fails to phase-lock to the NI 5606 4 GHz LO2 OUT through the
front panel, determine whether one of the following errors has occurred:
1.
Verify that the cable is not faulty and that all cables are connected to the correct
terminals.
2.
Verify that there is a reference signal generated from the NI 5606 4 GHz LO2 OUT front
panel connector.
If there is a 4 GHz signal coming from the NI 5653 LO2 OUT, the NI 5606 LO2 OUT
circuitry may be at fault. If there is a 4 GHz signal coming from the NI 5606 LO2 OUT,
the NI 5624R phase-lock circuitry may be at fault.
If there is a signal coming from the NI 5653 and NI 5606 and failures continue, contact
NI technical support or visit
If failures continue and there is no signal from the NI 5653 LO2 OUT connector, there may be
a problem with the NI 5653 hardware. Contact NI technical support or visit

What Should I Do if the NI-RFSA Soft Front Panel Does Not
Launch?
1.
Verify the front panel interconnections for your RF vector signal analyzer.
2.
Verify the MAX device association for your NI 5668R.
3.
If you have verified the interconnections and associations of your device and you are still
unable to launch the NI-RFSA SFP, try uninstalling and then reinstalling NI-RFSA.

What Should I Do if the Device Amplitude Reading Does Not
Match the Source?
1.
Verify that the discrepancy between the NI 5668R and the source is within the error limits
of the devices.
a)
Verify the absolute amplitude accuracy of the NI 5668R using the appropriate value.
b)
Verify the level accuracy of the input signal into the receiver.
