WFMPre:WFId? (Query Only)
Returns a descriptive string from the waveform specified in the DATa:SOUrce
command, if that waveform is on or displayed. If that waveform is not on or
displayed, the query fails and the oscilloscope generates an execution error with
event code 2244 (waveform requested is not on).

WFMPre:WFId?
None.
WFMPRE:WFId?
YT waveform:
:WFMPRE:WFID ”Ch1, DC coupling, 1.0E-1 V/div, 4.0E-4 s/div, 10000
points, Sample mode”
Non-FFT Math waveform:
:WFMPRE:WFID ”Math, DC coupling, 5.0E-2 V/div, 4.0E-4 s/div,
10000 points, Sample mode”
FFT waveform:
:WFMPRE:WFID ”Math, DC coupling, 2.0E1 dB/div, 4.0E-3 Hz/div,
10000 points, Sample mode”
WFMPre:<wfm>:WFId?
WFMPre:XINcr
The set form of this command specifies the interval (seconds per point for
non-FFT, Hertz per point for FFT) between samples of the reference waveform
specified by the DATa:DESTination command. The oscilloscope uses this value
to calculate the seconds/division or Hertz/division units shown in the status,
cursor and measurement readouts when displaying a reference waveform.
The query form returns the interval between samples of the waveform specified
by the DATa:SOUrce command, if that waveform is on or displayed. If that
waveform is not on or displayed, the query fails and the oscilloscope generates
an execution error with event code 2244 (waveform requested is not on).
