Waveform:format; Waveform:data - Rigol DS7034 User Programming Manual

RIGOL
Remarks NORMal: reads the waveform data currently displayed on the screen.

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.
RAW: reads the waveform data in the internal memory. Note: The data in the

internal memory can only be read when the oscilloscope is in the Stop state. You are
not allowed to operate the instrument when it is reading data.
When the channel source is set to MATH, only the NORMal mode is valid.

Return The query returns NORM, MAX, or RAW.
Format
Example :WAVeform:MODE RAW /*Sets the reading mode of waveform data to RAW.*/
:WAVeform:MODE?

:WAVeform:FORMat

Syntax :WAVeform:FORMat <format>

/*The query returns RAW.*/
Type
Discrete
WORD: Each waveform point occupies 2 bytes (16 bits). The lower 8 bits are valid
and the higher 8 bits are 0.
BYTE: Each waveform point occupies one byte (8 bits).
ASCii: The query returns the actual voltage value of each waveform point in
scientific notation; and the voltage values are separated by commas.
