:ACQuire:MDEPth
Syntax
:ACQuire:MDEPth <mdep>
:ACQuire:MDEPth?
Description
Set or query the memory depth of the oscilloscope (namely the number of waveform
points that can be stored in a single trigger sample). The default unit is pts (points).

Explanation
 For the analog channel:
― When a single channel is enabled, the range of <mdep> is {AUTO|12000|
120000|1200000|12000000|24000000}.
― When dual channels are enabled, the range of <mdep> is {AUTO|6000|60000|
600000|6000000|12000000}.
― When three/four channels are enabled, the range of <mdep> is {AUTO|3000|
30000|300000|3000000|6000000}.
For the digital channel:
― When 8 channels are enabled, the range of <mdep> is {AUTO|12000|120000|
1200000|12000000|24000000}.
― When 16 channels are enabled, the range of <mdep> is {AUTO|6000|60000|
600000|6000000|12000000}.
 The following equation describes the relationship among memory depth, sample
rate, and waveform length:
Memory Depth = Sample Rate x Waveform Length
Wherein, the Waveform Length is the product of the horizontal timebase (set by
the :TIMebase[:MAIN]:SCALe command) times the number of grids in the horizontal
direction on the screen (12 for MSO1000Z/DS1000Z).
When AUTO is selected, the oscilloscope will select the memory depth automatically
according to the current sample rate.
Return
Format
The query returns the actual number of points (integer) or AUTO.
Example
:ACQuire:MDEPth 12000 /*Set the memory depth to 12000pts*/
:ACQuire:MDEPth? /*The query returns 12000*/
