NOTE. You can also use the WAVFrm? query, which concatenates the WFMOutpre?
and CURVe? queries.
WFMOutpre? Q uery results
Explanation
WFMOUTPRE:BYT_NR 4
This value specifies the number of bytes per data point in the waveform data. To change
this value automatically, use the WFMOutpre:BYT_Nr command. Note that changing this
value automatically changes the
BIT_NR value accordingly. (This value can also be set
using the DATa:WIDth command.)
BIT_NR 32
This value specifies the number of bits per data point in the waveform data. To change this
value, use the WFMOutpre:BIT_Nrcommand. Note that changing this value automatically
changes the
BYT_NR value accordingly.
