Figure 7-44: SEM results for multiple sub blocks
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<n>:
LIMit<li>:FAIL? on page 1224 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<n>:MARKer<m>:FUNCtion:
POWer<sb>:RESult? on page 837.
The measured power trace can be queried using TRAC:DATA? and TRAC:DATA:X?,
see TRACe<n>[:DATA] on page 1143 and TRACe<n>[:DATA]:X? on page 1145:
The measured peak power list can be queried using TRAC:DATA? LIST, see
TRACe<n>[:DATA] on page 1143.
