Instrument Messages
Event Messages
–200 Execution Error; 
Preselector centering 
failed
Algorithm failed to center the preselector. This maybe caused by 
the signal peak being too low in amplitude. Or it could be from 
excessive CW input signal, alignment error, or hardware failure.
–200 Execution Error; Signal 
not stable enough to track
The signal that you have selected to track is changing too much 
for the function to track it properly.
–200 Execution Error; Store ref 
trace before turning on 
Normalize
The Reference trace data must be stored in the Ref trace before 
you turn on the Normalization function.
–200 Execution error; Sync word 
was not found.
NADC & PDC: In an EVM measurement, the sync word is not 
found and the synchronization cannot be established when Sync 
Word is selected in the Burst Sync menu.
Flexible Digital Demodulation: The sync word cannot be detected 
because of inappropriate parameter settings or incorrect signal.
–200 Execution error; Trace 
file contains no 
compatible traces.
The trace file may have been created by another version of the 
Phase Noise personality, which uses a different trace format that 
is incompatible with the version you are running. Please check 
you are running the most up to date version of the personality.
–200 Execution error; Trace 
file created by 
incompatible version of 
Phase Noise App
The trace file may have been created by another version of the 
Phase Noise personality, which uses a different trace format that 
is incompatible with the version you are running. Please check 
you are running the most up to date version of the personality.
–200 Function not available 
before Marker Zoom is 
performed 
Function not available before perform Marker Zoom 
–200 Must perform Scan before 
do Search
Cannot perform Search as the trace data is found empty
–200 No marked signal Cannot perform the selected function because no signal was 
marked. You must mark the peak of interest before selecting the 
function. 
–200 No Measure At Marker Added 
to Signal List
No signal peak was added into Signal List as there is no valid 
measure to Marker result. You must perform Measure at maker 
before selecting Measure At Marker --> List.
–200 No Peak Added to Signal 
List
No signal peak was added from the Search to Signal List as there 
is no signal peaks found within the defined parameters of the 
search criteria.
–200 Signal List is Empty Cannot perform the selected function because the signal list 
contains no data.
–200 Signal List is Full Cannot perform the selected function because the signal list is 
full. Please clear the list. 
–200 Signal Selected is not in 
the Signal List
The signal selected is not the list. You only can perform the 
operation on signal that is already available in the list.
