Appendix D: Waveform Transfer (WFMOutpre and CURVe

Query) Examples

Here are several examples of command sequences using the WFMOut pre? and

CURVe? queries to transfer data from the oscilloscope to a PC, with different

data sources, including Analog, Digital waveforms. Each command sequence

example is followed by an explanation of the returned

WFMOutpre? results.

The

WFMOut

pre?

values act as settings that apply to the CURVe query data

being transferred.

Here are se

veral examples of command sequences using the

WFMOutpre? and

CURVe? queries to transfer data from the oscilloscope to a PC, with different

data sources, including Analog,Digital , and RF frequency domain waveforms.

Each command sequence example is followed by an explanation of the returned

WFMOutpre? results. The WFMOutpre? values act as settings that apply to the

CURVe query data being transferred.

NOTE. I

n order to guarantee that the waveform data returned from

CURVE?

queries of multiple waveforms are correlated to the same acquisition, you

should use single sequence acquisition mode to acquire the waveform data

from a single acquisition. Single sequence acquisition mode is enabled using

ACQuire:STOPAfter

l: Transfer 10,000 points of analog channel waveform data from the

oscilloscope to a PC.
