Chapter 2 Command System RIGOL
MSO5000 Programming Guide 2-227
the command reads the memory waveform data, it returns the signal status of the
channel group where the currently selected channel sources reside. 1 byte
represents the status of one group of digital signals.
 When the waveform data in the internal memory are read in batches, the waveform
data returned each time might be the data in one area of the internal memory. In
"WORD" or "BYTE" return format, each returned data in blocks contain the TMC data
block header. Waveform data in two adjacent data blocks are consecutive.
:WAVeform:XINCrement?
Syntax
:WAVeform:XINCrement?
Description
Queries the time interval between two neighboring points of the currently selected
channel source in the X direction.
Remarks
 The returned value is related to the current data reading mode:
In NORMal mode, XINCrement = TimeScale/100.
In RAW mode, XINCrement = 1/SampleRate.
In MAX mode, XINCrement = TimeScale/100 when the oscilloscope is in the Run
state; XINCrement = 1/SampleRate when the oscilloscope is in the Stop state.
 The unit is related to the current channel source.
Return
Format
The query returns the time difference in scientific notation.
:WAVeform:XORigin?
Syntax
:WAVeform:XORigin?
Description
Queries the start time of the waveform data of the currently selected channel source in
the X direction.
Remarks
 The returned 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 the RUN state; the query returns the start time
of the waveform data in the internal memory when the instrument is in the Stop
state.
 The unit is related to the current channel source.
Return
Format
The query returns the time value in scientific notation.
:WAVeform:XREFerence?
Syntax
:WAVeform:XREFerence?
Description
Queries the reference time of the waveform points of the currently selected channel
source in the X direction.
Return
Format
The query returns 0 (namely the first waveform point on the screen or in the internal
memory).
