Commands Listed in Alphabetical Order
WFMINPRE:YMUL
T 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:YO
Ff
This command specifies the vertical position of the destination reference
waveform in digitizing levels. There are 25 digitizing levels per vertical division
for 1-byte
data, and 6400 digitizing levels per vertical division for 2-byte data.
Variations in this number are analogous to changing the vertical position of the
waveform.
The
WFMInpre:YMUlt, WFMInpre:YOFf, and WFMInpre:YZEro commands
are used to convert waveform record values to units specified using the
WFMInpre:YUNit command (YUNit units). It uses the following formula (where
dl means digitizing levels, and curve_in_dl is a data point value in the
CURVe
data):
Value in YUNit units = ((curve_in_dl - YOFf) * YMUlt) + YZEro
NOTE. For a given waveform record, YMUlt, YOFf, and YZEro have to be a
consi
stent set, otherwise vertical cursor readouts and vertical measurements may
give incorrect results.

Arguments
<NR3> is a floating point number that specifies 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; 0.0078125 division
for 16-bit data) above the center of the graticule.
