3 VMA Mode
3.9 SEM Measurement
Sweep Time Annotation (Remote Query Only)
Returns the Sweep Time Annotation value. Available only on non-sweeping
hardware.
The value returned is the estimated turnaround time of each acquisition, in seconds.
The turnaround time is the sum of the signal acquisition time, FFT time, and other
overhead time, to complete the entire carrier span of each measurement cycle.
Remote Command
[:SENSe]:SEMask:SWEep:ETIMe?
Example
:SEM:SWE:ETIM?
Dependencies Available only on non-sweeping hardware
Preset Automatically calculated
Sweep Type
Sets the Sweep Type used to calculate the power in the reference channel. Sweep
Type can be set manually or put into Auto mode.
How to define Channel Sweep Time and Channel Sweep Type:

Notes Sub op code, 1 is for BTS, 2 for MS. Default is BTS
Note that Sweep sub op code 2 is supported only in non-SA Modes. In SA Mode, Sweep sub op code 1
is used for both BTS and MS
