Arguments
<NR1> is the num
ber of data points if WFMInpre:PT_Fmt is set to Y. It is the
number of min-max pairs if WFMInpre:PT_Fmt is set to ENV.
Examples
WFMINPRE:NR_PT 5000 specifies that 5
000 data points will be transmitted.
WFMINPRE:NR_PT? might return :WFMINPRE:NR_PT 8000, indicating that there
are 8000 data points in the transmi
tted waveform record.
WFMInpre:PT_Fmt
This command sets or queries the point format of th e incoming waveform data.
Regardless of the argument used, the scale, offset, and so o n are interpreted
similarly. When ENV is used, waveform data is interpreted over the min-max
pair; when Y is used, it is interpreted over a single point.

Arguments
ENV spec ifies that the waveform is transmitted in envelope mode as maximum
and minimum point pairs. Only
Y values are explicitly transmitted. Absolute
coordinates are given by:
Xn = XZEro + XINcr (N-PT_Off)
Ynmax = YZEro + YMUlt (ynmax - YOFf)
Ynmin = YZEro + YMUlt (ynmin - YOFf)
Y speci fies a normal waveform where one ASCII or binary data point is
transmitted for each point in the waveform record. Only
Y values are explicitly
transmitted. Absolute coordinates are given by:
Xn = XZEro + XINcr (N-PT_Off)
Yn = YZEro + YMUlt (Yn - YOFf)
Examples
WFMINPRE:PT_FMT ENV sets the incoming waveform data point format to
enveloped.
WFMINPRE:PT_FMT? might return :WFMINPRE:PT_FMT ENV, indicating that the
waveform is transmitted as maximum and minimum point pairs.
