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 1246 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 862.
The measured power trace can be queried using
TRAC:DATA?
and
TRAC:DATA:X?
,
see
TRACe<n>[:DATA]
on page 1162 and
TRACe<n>[:DATA]:X?
on page 1163:
The measured peak power list can be queried using
TRAC:DATA? LIST
, see
TRACe<n>[:DATA]
on page 1162.
5.6.4 SEM basics
Some background knowledge on basic terms and principles used in SEM measure-
ments is provided here for a better understanding of the required configuration set-

5.6.4.1 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 5.6.5.1, " Sweep List " , on page 240.
