:WAVeform:PREamble?
Syntax
:WAVeform:PREamble?
Description
Queries the waveform parameter settings related to the waveform data reading.
Return Format
The query returns the parameter settings in strings in the following sequence, and the parameters are
separated by commas.
<format>,<mode>,<points>,<count>,<xincrement>,<xorigin>,<xreference>,<yincrement>,<yorigin>,
<yreference>
<format>: indicates 0 (BYTE), 1 (WORD), or 2 (ASCii). Refer to the :WAVeform:FORMat command.
<mode>: indicates 0 (NORMal), 1 (MAXimum), or 2 (RAW). Refer to the :WAVeform:MODE command.
<points>: indicates the number of waveform points to be read (in integer). Refer to the :WAVeform:POINts
command.
<count>: indicates the number of averages (refer to the :ACQuire:AVERages command) in "Average"
acquisition mode (refer to the :ACQuire:TYPE command). The <count> parameter is 1 in other modes.
<xincrement>: indicates the time difference (in scientific notation) between two neighboring points in the
X direction. Refer to the :WAVeform:XINCrement? command.
<xorigin>: indicates the start time (in scientific notation) of the waveform data in the X direction. Refer to
the :WAVeform:XORigin? command.
<xreference>: indicates the reference time (in integer) of the waveform data in the X direction. Refer to
the :WAVeform:XREFerence? command.
<yincrement>: indicates the unit voltage value (in scientific notation) in the Y direction. Refer to
the :WAVeform:YINCrement? command.
<yorigin>: indicates the vertical position (in integer) relative to the vertical reference position in the Y
direction. Refer to the :WAVeform:YORigin? command.
<yreference>: indicates the vertical reference position (in integer) in the Y direction. Refer to
the :WAVeform:YREFerence? command.
:WAVeform:RESet
Syntax
:WAVeform:RESet
Description
Resets the waveform data reading.
Remarks
This command is only applicable to reading waveform data in the internal memory (refer to
the :WAVeform:MODE command).
