3.8 SEM Measurement
Offset Detector
Same as "Offset Detector" on page 1103 under Offset (Bandwidth).
Start Freq
Same as "Start Freq" on page 1105 under Offset (Bandwidth).
Stop Freq
Same as "Stop Freq" on page 1109 under Offset (Bandwidth).
Sweep Time
Specifies the Sweep Time for the currently selected offset and enables you to toggle
the Sweep Time mode between Auto and Man.
When sending the remote command, missing values are not permitted; that is, if you
want to change values 2 and 6, you must send all values up to 6. Subsequent values
will remain unchanged. The query for this parameter returns 14 values for WLAN
mode, 12 values for other modes.
NOTE
On non-sweeping hardware, this column is grayed out. The value shown on this
column is an estimate. It is the turnaround time to complete the measurement of
the entire offset span, which is the sum of signal acquisition time, FFT time, and
other overhead time. If you need to specify the same “Sweep Time” as you would
for sweeping hardware, send [:SENSe]:SEMask:OFFSet[1]|2
[:OUTer]:LIST:SWEep:TIME <time>. The measurement emulates the “Sweep
Time” effect, but this emulation is not straightforward, and therefore the behavior
is not specified. Instead, we recommend using Minimum Acquisition Time,
which provides better control.
Remote Command
