preview parame
ters. The user should always follow acquisition parameter changes
with a single sequence OPC command prior to CURVe? to ensure the return data
reļ¬ects the new acquisition parameters.
The CURVe command transfers waveform data to the oscilloscope. The data
is stored in the reference memory location speciļ¬ed by DATa:DESTination,
starting with the data point speciļ¬ed 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, ļ¬rst 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.

For MSO models, reduced resolution waveform data is not available for

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.
