If the M8920A Radio Test Set is not communicating via the LAN connection,
check for the presence of blinking yellow LEDs on the rear panel LAN
connector. If the ACT LED is not blinking, check the LAN cable and LAN integrity.
The LAN connection is on the controller (either front panel of
the embedded controller, or wherever the LAN connection is
on the user-supplied controller.
To meet specifications, the module must be aligned. Refer to Step 6 - Verifying
Operation of the M8920A (page 67) .
Perform an Alignment. Select System > Alignments > Align Now > Align All
Now.
If the previously performed alignments did not resolve the problem, select the
System , Restore Align Defaults All. Then select the System , Align-
ments, Align Now, Align Now All.
Is the N9093 Radio Test mode displaying an error message? If so, refer to the
Instrument Messages Guide.
Check if the external frequency reference is selected but not available. Verify
that it is selected by choosing Input/Output, Freq Ref Input. The frequency of
the reference should be set correctly.
If you are using a Windows program other than the instrument application, you
may notice it running slow. Place the instrument application in Sweep, Sweep-
/Measurement, Single.
