WFMOUTPRE:XZE
RO?
might return :WFMOUTPRE:XZERO 5.6300E-9 indicating
that the trigger occurred 5.63 ns before the first sample in the waveform record.
WFMOutpre:YMUlt? (Query Only)
This query returns the vertical scale multiplying factor used to convert
the waveform data point values in the outgoing waveform record from
digitizing levels to the YUNit units. You can determine the units by using the
WFMOutpre
:YUNit
query.
See the description of the WFMInpre:YMUlt command to see how this scale
factor is
used to convert waveform sample values to volts.
If the waveform specified by DATa:SOUrce is not turned on, nothing is returned
andaner
ror event is generated.

Examples
WFMOUTPRE:YMULT? might return :WFMOUTPRE:Y MULT 4.0000E- 3 indicating
that the vertical scale for the corresponding waveform is 100 mV/div (for 8-bit
waveform data or 0.390625 V/div for 16–bit data).
WFMOutpre:YOFf? (Query Only)
This query returns the vertical position of the source 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. See the description of
WFMInpre:YOFf to see how this position 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.

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.
