:WFMOutpre?
Returns the following values. Each value represents the current settings that
a
CURVe?
query will use to format the data that will be transferred from the
oscilloscope to a PC or other device (see next table for explanations):

WFMOutpre? Query results
Explanation
BYT_NR 4
This value speci
fi
es the number of bytes per data point in the waveform data. This value
is
fi
xed for RF frequency domain traces.
BIT_NR 32
This value speci
fi
es the number of bits per data point in the waveform data. This value
is
fi
xed for RF frequency domain traces.
ENCDG ASCII
This value speci
fi
es the encoding of the waveform data. To change this value (the other
possibility for RF frequency domain traces is FPBINARY), use the WFMOutpre:ENCdg
command. This value can also be set using the DATa:ENCdg command.
BN_FMT FP
This value speci
fi
es the binary format, which in this case is FP (
fl
oating point). This value is
fi
xed for RF frequency domain traces. Note: This
fi
eld is not applicable for ASCii encoding.
BYT_OR MSB
This value speci
fi
es the byte order for the BINARY encoding, which in this case is MSB
(most signi
fi
cant byte
fi
rst, also known as IBM format). To change this value to LSB, use the
WFMOutpre:BYT_Or command. Note: This
fi
eld is not applicable for ASCii encoding.
WFID "RF_NORMAL, unknown
coupling, 10.00W/div, 200.0MHz/div,
1001 points, Sample mode, Center
Freq: 2.400GHz, Span: 2.000GHz,
Reference Level: 1.000mW"
This quoted string represents information about the source waveform that would be returned
by a WFMOutpre:WFId? Query. It cannot be changed.
NR_PT 21
This value indicates the number of data points in the waveform record. (If you would like to
determine only this value, use the WFMOutpre:NR_Pt? query.) Note: This value is typically
equal to the full record length of the RF frequency domain trace, but you also have the option
to transfer only a portion of the record using the DATs:STARt and DATa:STOP commands.
PT_FMT Y
This value indicates the format of the data points in the waveform record. In this case, the
value represents YF (Amplitude vs. Frequency) format. This is query only. (If you would like
to determine only this value, use the WFMOutpre:PT_Fmt? query.
PT_ORDER LINEAR .
This value is always LINear
