Arguments
<NR3> is the vertical scale factor per digitizing level of the incoming waveform
points.
Examples
WFMINPRE:YMULT? might return :WFMINPRE:YMULT 4 0.0000E-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 w aveform record, YMUlt, YOFf, and YZEro have to be a
consistent set, otherwise vertical cursor readouts and vertical measurements may
give incorrect results.
