Meas Offset
Specifies the time (in symbols) between the start of segment data and its reference.
For segment1, the reference is always the start of the capture data, meas offset is
always 0. And for segment2, the reference depends on the selection of Meas Offset
Reference, meas offset could be positive or negative. If positive, the segment2 starts
after the reference. If negative, the segment2 starts before the reference.

[:SENSe]:DDEMod:SEGMent1|…|6:TIME:OFFSet <integer>
[:SENSe]:DDEMod:SEGMent1|…|6:TIME:OFFSet?
Example
:DDEM:SEGM1:TIME:OFFS 10
:DDEM:SEGM1:TIME:OFFS?
Couplings Max and min constrained by Search Length, Meas Interval, Sync Pattern and Sync Search
Preset 0
State Saved Yes
Min/Max For segment1, it is 0
For segment2, it depends on Search Length, Meas Interval and Meas Offset Reference
Meas Interval
Sets the number of symbols that the demodulation will analyze. This and the symbol
rate set the overall time record length (in seconds) that is used by the demodulator.
It also indirectly sets the resolution bandwidth for the various spectrum results.
(ResBW cannot be set independently.)
The resolution bandwidth is annotated below any spectrum trace.
