WFMOutpre:CEN
TERFREQuency?
Examples
WFMOutpre:CENTERFREQuency? might return 1.0E+9, indicating a center
frequency of 1 GHz.
WFMOutpre:DOMain? (Query Only)
This query returns the domain of the outgoing waveform — either TIMe or
FREQuency. If the domain is TIMe, it indicates that the data is to be treated as
integer information. If the domain is FREQuency, it indicates that the dataistobe
treated as floating point information.
Conditions
MDO3000, MDO4000/B, or MDO4000C models with option SA3 or SA6 only.

Syntax
WFMOutpre:DOMain?
Examples
WFMOutpre:DOMain might return FREQuency, indicating that the outgoing
waveform is one of the four RF frequency domain traces (RF_NORMal,
RF_AVErage, RF_MINHOLD, RF_MAXHOLD).
WFMOutpre:ENCdg
This command specifies the type of encoding (BINary or ASCii) of the outgoing
waveform data queried using the
CURVe? query. (This can also be set using the
DATa:ENCdg command, which provides the ability to set
WFMOutpre:ENCdg,
WFMOutpre:BN_Fmt,
and WFMOutpre:BYT_ Or using a single command.)

WFMOutpre:BYT
_Or,
WFMOutpre:BIT_Nr,
WFMOutpre:BN_Fmt
Arguments
ASCii specifies that the outgoing data is to be in ASCII format. Waveforms
will be sent as
<NR1> numbers.
BINary specifies that outgoing data is to be in a binary format whose further
specification is determined by WFMOutpre:BYT_Nr, WFMOutpre:BIT_Nr,
WFMOutpre:BN_Fmt and WFMOutpre:BYT
_Or.
Examples
WFMOUTPRE:ENCDG? might return :WFMOUTPRE:ENCDG BIN indicating that
outgoing waveform data will be sent
in binary format.
WFMOUTPRE:ENCDG ASC specifies that the outgoing waveform data will be sent
in ASCII format.
WFMOutpre:NR_Pt? (Query Only)
This query returns the number of data points in the waveform record that will
be transmitted in response to a
CURVe? query. This value is the adjusted
range specified by
DATA:START and DATA:STOP commands. Note that the
oscilloscope automatically adjusts the
DATA:START and DATA:STOP values
when the
DATA:STOP valueislessthantheDATA:START value,andwhenthe
DATA:START and/or DATA:STOP value is greater than the record length of the
source waveform. The adjusted
DATA:START and DA TA:STOP values determine
WFMOUTPRE:NR_PT.(YoucanuseDATa:STARt and DATa:ST OP to transfer
partial waveforms.) If the waveform specified by the DATa:SOUrce command is
not turned on, an error will be generated.

WFMInpre:NR_Pt
Examples
WFMOUTPRE:NR_PT? might return :W FMOUTPRE:NR_PT 10000 indicating that
there are 10000 data points to be sent.
WFMOutpre:PT_Fmt? (Query Only)
This query returns the point format of the data points in the outgoing waveform
record transferred using the
CURVe? query. The returned values can be Y, which
indicates normal waveform points for YT format, or ENV, which indicates
envelope mode format in which the data is returned as a series of min/max pairs.
The minimum value precedes the maximum.
The outgoing waveform is specified by the DATa:SOUrce command. The query
command will time out and an error will be generated if the waveform specified
by DATa:SOUrce is not turned on.

Examples
WFMOUTPRE:PT_FMT? might return :WFMOutp re:PT_Fmt EN V in
dicating that
the waveform data is a series of min-max pairs.
WFMOutpre:PT_Off? (Query Only)
This query always returns 0 if the waveform specified by DATA:SOUrce is on or
displayed. If the waveform is not displayed, the query form generates an error. (It
is provided for compatibility with other Tektronix oscilloscopes).
