Waveform:preamble - Rigol DS7034 User Programming Manual

RIGOL
the start point and stop point of a reading operation are related to the memory depth of
the oscilloscope and the return format of the waveform data currently selected.
Return
The query returns an integer.
Format
Example :WAVeform:STOP 500
:WAVeform:STOP?

:WAVeform:PREamble?

Syntax
:WAVeform:PREamble?
Description Queries all the waveform parameters.
Return The query returns 10 waveform parameters, separated by commas.
Format
<format>,<type>,<points>,<count>,<xincrement>,<xorigin>,<xreference>,<yincrem
ent>,<yorigin>,<yreference>
Wherein,
<format>: indicates 0 (BYTE), 1 (WORD), or 2 (ASC).
<type>: indicates 0 (NORMal), 1 (MAXimum), or 2 (RAW).
<points>: After the memory depth option is installed, <points> is an integer ranging from
1 to 50000000.
<count>: indicates the number of averages in the average sample mode. The value of
<count> parameter is 1 in other modes.
<xincrement>: indicates the time difference between two neighboring points in the X
direction.
<xorigin>: indicates the start time of the waveform data in the X direction.
<xreference>: indicates the reference time of the waveform data in the X direction.
<yincrement>: indicates the step value of the waveforms in the Y direction.
<yorigin>: indicates the vertical offset relative to the "Vertical Reference Position" in the Y
direction.
<yreference>: indicates the vertical reference position in the Y direction.
Example :WAVeform:PREamble?
/*The query returns

2-230
/*Sets the stop point to 500.*/
/*The query returns 500.*/
