ters. The user should always follow acquisition parameter changes
with a single sequence OPC command prior to CURVe? to ensure the return data
reflects the new acquisition parameters.
The CURVe command transfers waveform data to the oscilloscope. The data
is stored in the reference memory location specified by DATa:DESTination,
starting with the data point specified by DATa:STARt. Only one waveform can
be transferred at a time. The waveform will only be displayed if the reference
is displayed.
For CURVe queries, first set DATa:RESOlution and DATa:COMPosition
appropriately. For MSO/DPO2000/B math FFT CURVe queries, set them to:
DATA:RES
OLUTION FULL
and DATA:COMPOSITION SINGULAR_YT.
For more information, see: Appendix B: Waveform Data in MSO/DPO2000B
and MSO/
DPO2000 Series Instruments.
(See page B-1.)

For MSO models, reduced resolution waveform data is not available for
the digital channels.

Arguments
<Block> is the waveform data in binary format. The waveform is formatted as:
#<x><yyy><data><newline>, where:
<x> is the number of y bytes. For example, if <yyy>=500, then <x>=3)
<yyy> is the number of bytes to transfer if samples are one or two bytes
wide. Use the WFMInpre:BYT_Nr command t o set the width for waveforms
transferred into the oscilloscope. Use WFMOutpre:BYT_Nr to set the width
for waveforms transferred out from the oscilloscope.
