WFMPre:YMUlt
YMUlt is a value, expressed in YUNits per digitizer level, used to
convert waveform record values to YUNit values using the following
formula (where dl is digitizer levels):
value_in_YUNits = ((curve_in_dl ā YOFF_in_dl) * YMUlt) +
YZERO_in_YUNits
The set form of this command sets the vertical scale factor of the
reference waveform specified by the DATa:DESTination command,
expressed in YUNits per digitizing level.
The query form returns a value for the waveform specified by the
DATa:SOUrce command, if that waveform is active or displayed. If
that waveform is not active or displayed, the query fails and the
oscilloscope generates an execution error with event code 2244
(waveform requested is not active).
Waveform
WFMPre:YMUlt <NR3>
WFMPre:YMUlt?
<NR3> is the vertical scale factor, in YUNits (usually volts) per
sample value.
An argument value of zero has special meaning. A zero indicates
that the waveform has unknown vertical scaling. An example of
unknown vertical scaling is a math waveform of CH1+CH2 where
CH1 vertical scaling is different from CH2 vertical scaling. In this
case, WFMPre:YUNit? returns U.
