: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).
Parameter

Type
Discrete
When a single channel is on: {AUTO|12000|120000|1200000|12000000|24000000}
When dual channels are on: {AUTO|6000|60000|600000|6000000|12000000}
When four channels are on: {AUTO|3000|30000|300000|3000000|6000000}
Wherein, 24000000, 12000000 and 6000000 are options.
The relationship among the memory depth, sample rate and waveform length
satisfies the following equation:
Memory Depth ＝ Sample Rate × Waveform Length
Wherein, the Waveform Length is the product of the horizontal timebase (set by
the :TIMebase[:MAIN]:SCALe
(12 for DS1000Z).
When AUTO is selected, the oscilloscope will select the memory depth automatically
according to the current sample rate.
Range

command) times the number of the horizontal scales
/*Set the memory depth to 12000*/
/*The query returns 12000*/
