Command Descriptions

WFMPre:<wfm>

:NR_Pt? (Query Only)

NOTE. This query is not available when using a TDS210 or TDS220 oscilloscope

(ﬁrmware below V 2.00) with a TDS2CMA communications module.

Returns the number of points that are in the transmitted waveform record.

The number of points depends on DATa:STARt, DATa:STOP, and whether

DATa:SOUrce is YT or FFT. NR_Pt is at most 2500 for YT and 1024 for FFT.

NR_Pt is always at least one.

When the DATa:SOUrce is not displayed, the oscilloscope will generate an error

and return event code 2244.
