Acquire:mdepth; Acquire:srate; Acquire:type - Rigol DS4000E Series Programming Manual

Chapter 2 Command System

:ACQuire:MDEPth

Syntax
:ACQuire:MDEPth <mdep>
:ACQuire:MDEPth?
Description
Sets or queries the memory depth of the oscilloscope (namely the number of waveform points that can be
stored through sampling in a single trigger). The default unit is pts (points).
Parameter
Name Type
<mdep> Discrete
Remarks
The formula below describes the relationship among memory depth, sample rate, and waveform length:
Wherein, waveform length = horizontal time base x number of grids in the horizontal direction on the
screen. For DS4000E, the number of grids in the horizontal direction on the screen is a fixed value 14. When
<mdep> is set to "AUTO", the oscilloscope will select the memory depth automatically according to the
current sample rate and horizontal time base (refer to the :TIMebase[:MAIN]:SCALe command).
Return Format
The query returns an integer.

:ACQuire:SRATe?

Syntax
:ACQuire:SRATe?
Description
Queries the current sample rate of the oscilloscope. The default unit is Sa/s.
Return Format
The query returns the sample rate in scientific notation.

:ACQuire:TYPE

Syntax
:ACQuire:TYPE <type>
:ACQuire:TYPE?
Description
Sets or queries the data acquisition mode of the oscilloscope.
Parameter
Name Type
<type> Discrete
Remarks
NORMal: In this mode, the oscilloscope samples the signal at the same interval to reconstruct the

waveform. For most of the waveforms, this mode can realize the best display effects.
AVERages: In this mode, the oscilloscope will acquire the waveform samples for several times, then
