ion, WFMInpre:BYT_Nr, WFMInpre:YUNit
Arguments
<NR3> is the vertical scale factor per digitizing level of the incoming waveform
points.
Examples
WFMINPRE:YMULT? might return :WFMI NPRE:YMULT 40.0000E-3,which(if
YUNit is “V”) indicates that the vertical scale is 40 mV/digitizing level (1V/div
for 8-bit data).
WFMINPRE:YMULT 20E-3 specifies that (if WFMInpre:YUNit is "V" and
WFMInpre:BYT_Nr is 1), the vertical scale is 20 mV/digitizing level
(500 mV/div).
WFMInpre:YOFf
Sets or returns the vertical position of the incoming waveform in digitizing levels.
Variations in this number are analogous to changing the vertical position of the
waveform.
YMUlt, YOFf, and YZEro are used to convert waveform record values to YUNit
values using the following formula (where dl is the data level; curve_in_dl is a
data point in CURVe):
value_in_units = ((curve_in_dl - YOFf_in_dl) * YMUlt) + YZEro_in_units
NOTE. For a given waveform record, YMUlt, YOFf, and YZEro have to be a
consistent set, otherwise vertical cursor readouts and vertical measurements may
give incorrect results.

WFMInpre:BYT_Nr, WFMInpre:YMUlt, WFMOutpre:YOFf?
Arguments
<NR3> is the vertical offset in digitizing levels.
Examples
WFMINPRE:YOFF 50 specifies that the zero reference point for the incoming
waveform is 50 digitizing levels (2 divisions, for 8-bit data) above the center
of the data range.
