Examples
WFMOUTPRE:YOFF? might return :WFMOUTPRE:YOFF - 50.0000E+0 indicating
that the position indicator for the waveform was 50 digitizing levels (2 divisions)
below cen
ter screen (for 8-bit waveform data).
WFMOutpre:YUNit? (Query Only)
This query returns the units of data points in the outgoing waveform record
transferred using the
CURVe? query. This can be any of several string values,
depending upon the vertical units of the source waveform (specified by the
DATa:SOUrce command). Typically, this is “V” for volts. If the waveform
speci
fied by DATa:SOUrce is not turned on, nothing is returned and an error
event is generated.

Examples
WFMOUTPRE:YUNIT? might return :WFMOUTPRE:YUNIT "dB" indicating that
the vertical units for the waveform are measured in decibels.
WFMOutpre:YZEro? (Query Only)
This query returns the vertical offset of the source waveform. You can
determine the units using the WFMOutpre:YUNit? query. See the description of
WFMInpre:YZEro to see how this offset is used to convert waveform sample
values to volts. If the waveform specified by DATa:SOUrce is not turned on,
nothing is returned and an error event is generated.
