Programming Manual
Returned value is related to the current data reading mode, time of trigger point is zero, before the trigger
point is negative.
In NORMal mode, return start time of waveform data displayed on the screen: XORigin = -1*TimeScale*7
In RAW mode, return start time of waveform data in internal storage, XORigin = -1*
(SamplePoints/SampleRate)/2
Return format：

Query returns time value, unit is s.
For example：

:WAV:XOR?
:WAVeform:XREFerence?
Command format：

:WAVeform:XREFerence?
Functional description：

This command is used to query the reference time benchmark of waveform point of the currently selected
channel source in X direction, it's always zero.
Return format：

Query reference time benchmark, query returns 0.
For example：

:WAV:XREF?
:WAVeform:YINCrement?
Command format：

:WAVeform:YINCrement?
Functional description：

This command is used to query the unit of voltage of current selected channel source in Y direction, unit
is the same with the current amplitude unit.
Returned value is related to the current data readinging mode:
YINCrement = VerticalScale/ waveform point of amplitude scale in vertical position (25)
Return format：

Query returns unit voltage value in Y direction.
For example：

:WAV:YINC?
:WAVeform:YORigin?
Command format：

:WAVeform:YORigin?
Functional description：

This command is used to query the currently selected channel source in Y direction relative to vertical
displacement of the vertical reference position.
Returned value is related to the current data reading mode, up is positive and down is negative with the
reference as the base:
YORigin = VerticalOffset/YINCrement
