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 1055 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 749.
The measured power trace can be queried using TRAC:DATA? and TRAC:DATA:X?,
see TRACe<n>[:DATA] on page 975 and TRACe<n>[:DATA]:X? on page 976:
The measured peak power list can be queried using TRAC:DATA? LIST, see
TRACe<n>[:DATA] on page 975.

7.6.4.1 Ranges and Range Settings
In the Spectrum Emission Mask measurements, a range defines a segment for which
you can define the following parameters separately:
●
Start and stop frequency
●
RBW
●
VBW
●
"Sweep Time"
●
"Sweep Points"
●
Reference level
●
Attenuator settings
●
Preamplifier settings
●
Transducer settings
●
Limit values
Via the sweep list, you define the ranges and their settings. For details on settings,
refer to Chapter 7.6.5.1, " Sweep List ", on page 221.
