Examples
WFMOUTPRE:PT_OFF?
might return
:WFMOUTPRE:PT_OFF 251
specifying that
the trigger actually occurred between points 250 and 251.
WFMOutpre:WFId? (Query Only)
This query-only command returns a string describing several aspects of the
acquisition parameters for the waveform speci
fi ed by the DATa:SOUrce command.
An error is reported if the DATa:SOUrce waveform does not exist.

Field Description Examples
Source The source identi fi cation string as it appears in
the front panel scale factor readouts.
"CH1–8"
"Math<x>
"Ref<x>"
Coupling A string describing the vertical coupling of the
waveform (the Source1 waveform in the case of
Dual Waveform Math). "AC coupling"
"DC coupling"
"GND coupling"
Vert Scale A string containing the vertical scale factor of
the unzoomed waveform. The numeric portion
will always be four digits. The examples cover

"500.0
μ Vs/div"
"10.00 kV/s/div"
"200.0 mV/div"
"50.00 unk/div"
Horiz Scale A string containing the horizontal scale factor of
the unzoomed waveform. The numeric portion
will always be four digits. The examples cover
all known internal units. "100 ms/div"
"10.00 kHz/div"
"50.00 c/div"
