WFMPre:YMUlt <NR3>
WFMPre:YMUlt?
<NR3> is the vertical scale factor, in YUNits (usually volts) per data point level.
WFMPre:YUNit
WFMPre:YOFf
YOFf specifies the vertical position of a waveform. YOFf is a value, expressed
in waveform data point levels, used to convert waveform record values to YUNit
values using the following formula (where dl is data levels; curve_in_dl is a data
point from CURVe?):
value_in_units =
((curve_in_dl -- YOFF_in_dl) * YMULT) + YZERO_in_units
The set form of this command stores a value for the reference waveform
specified by the DATa:DESTination command. This value does not affect how
the oscilloscope displays the waveform, but does affect the cursor readouts and
vertical measurements.
The query form returns the vertical position of the waveform specified by the
DATa:SOUrce command, in data levels, if that waveform is on or displayed. If
that waveform is not on or displayed, the query fails and the oscilloscope
generates an execution error with event code 2244 (waveform requested is not
on).
Waveform
