2 Command System RIGOL
DS2000E Programming Guide
:WAVeform:XORigin?
Syntax
:WAVeform:XORigin?
Description
Query the start time of the waveform data of the channel source currently selected (refer to
the
:WAVeform:SOURce command) in the X direction.
Explanation
The return value is related to the current data reading mode:
In NORMal mode, the query returns the start time of the waveform data displayed on the screen.
In RAW mode, the query returns the start time of the waveform data in the internal memory.
In MAXimum mode, the query returns the start time of the waveform data displayed on the screen
when the instrument is in running status; the query returns the start time of the waveform data in
the internal memory when the instrument is in stop status.
The unit is related to the current channel source:
When the channel source is CHANnel1 or CHANnel2, the unit is s.
When the channel source is MATH with FFT operation or the channel source is FFT, the unit is Hz.
Return Format
The query returns the start time of the waveform data of the channel source currently selected in the X
direction in scientific notation.
:WAVeform:XREFerence?
Syntax
:WAVeform:XREFerence?
Description
Query the reference time base of the channel source currently selected (refer to the
:WAVeform:SOURce
command) in the X direction.
Return Format
The query returns 0 (namely the first waveform point on the screen or in the internal memory).
