YZERO is in vertical units; in this example, 0.0 Volts.
YMULT is in vertical units per digitizing level (DL), in this example,
0.004 Volts per digitizing level.

Further Explanation of the
Digital Collection
When the waveform source is set to DIGital using the DATa:SOUrce command, a
WFMOutpre? and CURVe? query (or a WAVFRM? query) will return the Digital
Collection data. The format and content of this data will depend upon the width
that has been specified using the
DATa:WIDth command, which can be either
4 or 8 bytes per point.
NOTE. Applies to MSO/MDO4000/B models only as well as MDO3000 and
MDO4000C models with option MDO3MSO or MDO4MSO installed.
4 Byte Data. When the data width is set to 4 bytes (using either DATa:WIDth or
WFMOutpre:BYT_Nr, the Digital Collection represents
the states of digital channe
ls D0 – D15,
the digital representations of analog Channels 1 – 4, and
the trigger state.
