WFMPre:XINcr <NR3>

WFMPre:XINcr?

<NR3> is the interval between points in the waveform record, in the

units specifed by WFMPre:XUNit. Note that at some fast sweeps,

some points in the waveform record are produced by interpolation.

DATa:SOUrce CH1 WFMPre:XINcr

might return :WFMPRE:XINCR 2.0E−6

WFMPre:XUNit

For all model and firmware combinations except the TDS200 series

with a TDS2CMA communications module, the set form of this

command specifies the horizontal units ("s" for seconds and Hz"

for Hertz) for the reference waveform specified by the DATa:DES-

Tination command. Setting a reference waveform to Hz causes the

oscilloscope to display the waveform as an FFT waveform.

NOTE . For TDS200 oscilloscopes used with a TDS2CMA commu-

nications module, the set form is ignored.

The query form returns the horizontal units for the waveform

specified by DATa:SOURce. If the waveform specified by

DATa:SOURce is not displayed, the query generates event message

2244.
