:WAVeform:YREFerence?
Syntax
:WAVeform:YREFerence?
Description
Queries the vertical reference position of the currently selected channel source in the Y
direction.
Remarks
The returned value is related to the current data reading mode.
In NORMal mode, YREFerence is a fixed value 128 (screen bottom is 0 and screen top is
255).
In RAW mode, YREFerence is related to the VerticalScale of the memory waveforms and
the currently selected VerticalScale.
In MAX mode, when the instrument is in the RUN state, YREFerence is a fixed value 128
(screen bottom is 0 and screen top is 255); when the instrument is in the STOP state,
YREFerence is related to the VerticalScale of the memory waveforms and the currently
selected VerticalScale.
Return
Format
The query returns an integer.
:WAVeform:STARt
Syntax
:WAVeform:STARt <sta>
:WAVeform:STARt?
Description
Sets or queries the start position of waveform data reading.
Parameter
Name
Type
Range
Default
<sta>
Integer
NORMal: 1 to 1000
MAX: 1 to the number of effective points on the
current screen
RAW: 1 to the current maximum memory depth
1
Remarks
When reading the waveform data in the internal memory, the actual settable ranges of 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
Format
The query returns an integer.
Example
:WAVeform:STARt 100 /*Sets the start point to 100.*/
:WAVeform:STARt? /*The query returns 100.*/
:WAVeform:STOP
Syntax
:WAVeform:STOP <stop>
:WAVeform:STOP?
Description
Sets or queries the stop position of waveform data reading.
Parameter
