Manual operation: See "3D Spectrogram State" on page 599
CALCulate<n>:SGRam:TRACe <Trace>
CALCulate<n>:SPECtrogram:TRACe <Trace>
This command determines the trace in the result display the Spectrogram is based on.
Suffix:
<n>
.

Parameters:
<Trace> TRACE1 | TRACE2 | TRACE3 | TRACE4 | TRACE5 | TRACE6
How many traces are available depends on the selected result
display.
Example:
CALC2:SPEC:TRAC TRACE3
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 1143.

Query parameters:
<Frames> CURRent
Returns the starting time of the current frame.
ALL
Returns the starting time for all frames. The results are sorted in
descending order, beginning with the current frame.
Return values:
<Seconds> Number of seconds that have passed since 01.01.1970 till the
frame start
<Nanoseconds> Number of nanoseconds that have passed in addition to the
<Seconds> since 01.01.1970 till the frame start.
