10537 Cancellation trace has different X-Scale to Smoothed trace.
When performing phase noise cancellation, you need to supply a reference
trace that will be used to cancel out the background noise of the analyzer.
The reference trace must have been measured over the same range of
offsets, and on the same instrument as the current measurement being
performed.
10560 Carrier Not Present. Verify frequency and amplitude settings.
No Carrier > –50 dBm found at the analyzer input within the search span.
Solution: Modify center frequency to be closer to actual carrier, or
alternatively apply carrier of sufficient amplitude at the current center
frequency.
10561 Signal Tracking disabled when measuring DANL Floor (Removal).
Measuring the DANL Floor with DANL Method set to Removal requires
that the user remove the signal and attach a load to the analyzer RF
Input. Signal Tracking requires that the carrier be measured many times
per measurement, so the two are inherently incompatible.
10601 to 10700: GSM and EDGE Error Messages (Options BAH and 202) An error
number in this range indicates the instrument has detected an error relating to the GSM
or EDGE personality.
10602 Sync word not found
An attempt to position a GSM trace into the mask, when not enough data
was present. Try using the
Restart key to clear the problem. This can be
caused by a bad GSM burst, or the RF Sync Delay set too far.
10604 GSM burst out of limits
The GSM signal did not fit into the mask in the Power vs. Time
measurement.
10606 Insufficient pre-Trig for demod - decrease Trig Delay
10608 Incorrect RBW for demod - change RBW
10610 GSM Hopping enabled, waiting for valid burst
10612 Invalid GSM burst timing
A GSM-like burst was acquired, but its timing is not valid. Ensure the
correct
Burst Type has been selected.
10614 Valid GSM burst not found
In a GSM measurement, data was acquired but a GSM burst was not
found, with the timeslot mode disabled.
10616 Cannot synchronize frame trigger
Cannot synchronize the frame trigger to the even second clock.
