TDS200/1000/2000 Series Oscilloscope Programmer Manual
WFMPre:<wfm>? (Refer to Waveform Mnemonics on page 2-9 for
more information.)
The format of the response is:
:WFMPre:<wfm>:WFID <Qstring>;PT_FMT { ENV | Y };
XINcr <NR3>;PT_Off <NR1>;XZEro <NR3>;XUNit <QString>;
YMUlt <NR3>;YZEro <NR3>;YOFF <NR3>;YUNit <QString>;
NR_Pt <NR1>
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 communica-
tions 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.
Waveform
WFMPre:<wfm>:NR_Pt?
WFMPre:CH1:NR_Pt?
returns <NR1>, which is the number of data points. If DATa:WIDth is
2, then there are <NR1>*2 bytes in the curve.
