PNA Compression Marker Functionality in SCPI

Question asked by andyTPE on Jan 31, 2012

I am running a PNA-X with f/w A.09.42.01 and have a power sweep setup at a fixed frequency.  I can activate a compression marker to find the P1dB compression point without any issues.

Is there a simple way to determine whether the marker has found the compression point?  Assume my input power sweep is from 0 to 10 dBm.  If the input compression point exceeds 10 dBm, then obviously the search will not find the compression point - and it gets reported to the front screen 'Comp. Not Found' message).  Is there any way to pro grammatically query this status via SCPI.  I could always test for the case: if CompIn=Pstop then assume compression point not found (so I will artificially fail all cases where P1dB is actually right on the P1dB edge), but this means I will need to either query or track the Pstop setting in the compression marker function.

Thank you
