2-350 MSO2000A/DS2000A 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. The unit is s.
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 MAX 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, CHANnel2 or any of D0 to D15, 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. The unit is s.
Return Format
The query returns 0 (namely the first waveform point on the screen or in the internal memory).
