:ACQuire Commands
The :ACQuire commands are used to set the memory depth of the oscilloscope, the acquisition mode, the
average times, as well as query the current sample rate.

: In the "Command List" in this manual, the query commands and the parameters in the setting commands are
omitted. You can refer to the complete introductions of the commands in the body of the text based on the keywords
listed here.
:ACQuire:AVERages
Syntax :ACQuire:AVERages <count>
:ACQuire:AVERages?
Description
Sets or queries the number of averages in the average acquisition mode.
Parameter

Default
<count>
Integer

n
(n is an integer, and its range is from 1 to 16)

Remarks  You can send the :ACQuire:TYPE command to set the acquisition mode.
 In the average acquisition mode, greater number of averages can lower the noise
and increase the vertical resolution; but will also slow the response of the displayed
waveform to the waveform changes.
Return
Format
The query returns an integer ranging from 2 to 65536.
Example
:ACQuire:AVERages 128 /*Sets the average times to 128.*/
:ACQuire:AVERages? /*The query returns 128.*/
:ACQuire:MDEPth
Syntax :ACQuire:MDEPth <mdep>
:ACQuire:MDEPth?
Description Sets or queries the memory depth of the oscilloscope (i.g. the number of waveform
points that can be stored through the sampling in a single trigger). The default unit is pts.

AUTO
Remarks  When "AUTO" is selected, the oscilloscope selects the memory depth automatically
according to the current sample rate.
 The maximum memory depth for the single channel is 100 M; the maximum memory
