WFMInpre:WFMT
YPe
Arguments
TIMe specifies to treat the information to be transferred as integer values.
FREQuency specifies to treat the information to be transferred as floating point
values.
Examples
WFMInpre:DOMain FREQuency specifies to treat the information to be
transferred from a PC to a reference location as floating point values.
WFMInpre:DOMain? might return TIME, indicating that the information is being
treated as integer values (time domain).
WFMInpre:ENCdg
This command specifies the type of encoding of the incoming waveform data
to be sent to the oscilloscope using the
CURVe command. Supported types are
BINary and ASCii.

Syntax
WFMInpre:ENCdg {ASCii|BINary}
WFMInpre:ENCdg?
Related Commands
WFMOutpre:ENCdg
Arguments
ASCii specifies that the incoming data is in ASCII format.
BINary specifies that the incoming data is in a binary format whose further
interpretation requires knowledge of BYT_NR, BIT_NR, BN_FMT, and
BYT_OR.
Examples
WFMINPRE:ENCDG ASC sets the format of incoming waveform data to ASCII
format.
WFMINPRE:ENCDG ? might return :WFMINPRE: ENCDG BIN indicating that the
incoming waveform data is in binary format.

WFMInpre:NR_Pt
This command specifies the number of data points that are in the incoming
waveform record to be sent to the oscilloscope using the
CURVe command.

WFMOutpre:NR_Pt?
Arguments
<NR1> is the number 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 10000 specifies that 10000 data points will be expected.
WFMINPRE:NR_PT ? might return :WFMINPRE:NR_PT 10 000 indicating that
there are 10000 data points in the expected incoming waveform record.
WFMInpre:PT_Fmt
This command specifies the acquisition format of the data points to be sent tothe
oscilloscope using the
CURVE command. This can be Y for YT format, or ENV
for envelope mode (min/max pairs). For YT format, each data value represents a
single waveform data point. For envelope format, each data point represents a
min/max pair, where the minimum value precedes the maximum value.

Syntax
WFMInpre:PT_F
mt {ENV|Y}
WFMInpre:PT_Fmt?
Related Commands
WFMOutpre:PT_Fmt?
Arguments
ENV specifies that the waveform is to be transmitted in envelope mode as
minimum and maximum 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 specifies 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 :WFMIN PRE:PT_FMT ENV indicating that the
waveform is transmitted as minimum and maximum point pairs.
WFMInpre:PT_Off
The set form of this command is ignored. The query form always returns a 0.
(This command is listed for compatibility with other Tektronix oscillos
copes.)
