:WAVeform:YREFerence?
Query the vertical reference position of the specified channel source in the Y direction.
The return value is related to the current data reading mode:
In NORMal mode, YREFerence is always 127 (the screen bottom is 0 and the screen top is
255).
In RAW mode, YREFerence is related to the Verticalscale of the internal waveform and the
Verticalscale currently selected.
In MAX mode, YREFerence is always 127 (the screen bottom is 0 and the screen top is
255) when the instrument is in running status; YREFerence is related to the Verticalscale
of the internal waveform and the Verticalscale currently selected when the instrument is in
stop status.
The query returns an integer.
:WAVeform:STARt
:WAVeform:STARt <sta>
:WAVeform:STARt?
Set or query the start point of waveform data reading.
NORMal: 1 to 1200
MAX: 1 to the number of effective points
currently on the screen
RAW: 1 to the current maximum memory depth
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; for the
details, refer to the explanation in the :WAVeform:DATA? command.
The query returns an integer.
:WAVeform:STARt 100 /*Set the start point to 100*/
:WAVeform:STARt? /*The query returns 100*/
