average the neighboring points of the sample waveform to reduce the random noise
on the input signal and generate much smoother waveforms on the screen. This is
generally used when the sample rate of the digital converter is higher than the
storage rate of the acquisition memory.
Return
Format
The query returns NORM, AVER, PEAK, or HRES.
Example
:ACQuire:TYPE AVERages /*Select the average acquisition mode*/
:ACQuire:TYPE? /*The query returns AVER*/
:ACQuire:SRATe?
Syntax
:ACQuire:SRATe?
Description
Query the current sample rate. The default unit is Sa/s.
Explanation  Sample rate is the sample frequency of the oscilloscope, namely the waveform points
sampled per second.
 The following equation describes the relationship among memory depth, sample
rate, and waveform length:
Memory Depth = Sample Rate x Waveform Length
Wherein, the Memory Depth can be set using the
:ACQuire:MDEPth command, and
the Waveform Length is the product of the horizontal timebase (set by
the
:TIMebase[:MAIN]:SCALe command) times the number of the horizontal scales
(12 for DS1000Z-E).
Return
Format
The query returns the sample rate in scientific notation.
Example
:ACQuire:SRATe? /*The query returns 2.000000e+09*/
