Retrieving Results via Remote Control
The measurement results of the spectrum emission mask test can be retrieved using
the CALC:LIM:FAIL? command from a remote computer; see CALCulate:
LIMit<k>:FAIL? on page 987 for a detailed description.
The power result for the reference range can be queried using
CALC:MARK:FUNC:POW:RES? CPOW;
The peak power for the reference range can be queried using
CALC:MARK:FUNC:POW:RES? PPOW, see CALCulate:MARKer:FUNCtion:
POWer<sb>:RESult? on page 696.
The measured power trace can be queried using TRAC:DATA? and TRAC:DATA:X?,
see TRACe<n>[:DATA] on page 922 and TRACe<n>[:DATA]:X? on page 924:
The measured peak power list can be queried using TRAC:DATA? LIST, see
TRACe<n>[:DATA] on page 922.
