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
remain unchanged. The query for this parameter always returns 12 values.
NOTE
On non-sweeping hardware, this column is grayed-out. The value shown on this
column is an estimate of 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:INNer: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" on page 1675, which provides better control.
Remote Command
[:SENSe]:SEMask:OFFSet[1]|2:INNer:LIST:SWEep:TIME <time>, …
[:SENSe]:SEMask:OFFSet[1]|2:INNer:LIST:SWEep:TIME?
[:SENSe]:SEMask:OFFSet[1]|2:INNer:LIST:SWEep:TIME:AUTO ON | OFF | 1 | 0, …
[:SENSe]:SEMask:OFFSet[1]|2:INNer:LIST:SWEep:TIME:AUTO?
Example
:SEM:OFFS2:INN:LIST:SWE:TIME 1.0 ms, 3.4 ms, 2.08 ms, 1.0 ms, 1.0 ms, 1.0 ms
:SEM:OFFS2:INN:LIST:SWE:TIME?
:SEM:OFFS2:INN:LIST:SWE:TIME:AUTO ON, ON, ON, ON, OFF, OFF
:SEM:OFFS2:INN:LIST:SWE:TIME:AUTO?
Notes OFFSet 1 is for BTS, 2 for MS. Default is BTS
Dependencies On non-sweeping hardware, this column is grayed-out and the Auto/Man checkbox is invisible. The
read-only column shows estimated sweep time
In those instruments, "Minimum Acquisition Time" on page 1675 is available
Couplings When you manually set a value while in Auto , the state automatically changes to Man
