CALCulate<n>:SGRam:TSTamp:DATA? <Frames>
CALCulate<n>:SPECtrogram:TSTamp:DATA? <Frames>
This command queries the starting time of the frames.
The return values consist of four values for each frame. If the Spectrogram is empty,
the command returns '0,0,0,0'. The times are given as delta values, which simplifies
evaluating relative results; however, you can also calculate the absolute date and time
as displayed on the screen.
The frame results themselves are returned with
TRAC:DATA? SGR
See
TRACe<n>[:DATA]
on page 832.
