Waveform:mode; Waveform:points - Rigol DS4000E Series Programming Manual

Chapter 2 Command System

:WAVeform:MODE

Syntax
:WAVeform:MODE <mode>
:WAVeform:MODE?
Description
Sets or queries the reading mode of the waveform data.
Parameter
Name Type
<mode> Discrete
Remarks
NORMal: reads the waveform data displayed on the screen.

RAW: reads the waveform data in the internal memory.
MAXimum: reads the waveform data displayed on the screen when the oscilloscope is in the Run state;
reads the waveform data in the internal memory when the oscilloscope is in the Stop state.
Note: The waveform data in the internal memory can only be read when the oscilloscope is in the Stop
state; besides, you cannot operate the oscilloscope during the reading process.
When the source channel of waveform data reading is set to MATH or FFT (refer to

the :WAVeform:SOURce command), only the waveform data displayed on the screen can be read, and
the waveform data in the internal memory cannot be read at this time.
Return Format
The query returns NORM, RAW, or MAX.

:WAVeform:POINts

Syntax
:WAVeform:POINts <point>
:WAVeform:POINts?
Description
Sets or queries the number of the waveform points to be read.
Parameter
Name Type
<point> Integer
Remarks
The range of <point> is related to the current waveform data reading mode (refer to
the :WAVeform:MODE command).
NORMal mode: 1 to 1400

RAW mode: 1 to the current maximum memory depth

MAXimum mode: 1 to the number of effective points currently on the screen

Return Format
The query returns an integer.
