: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 MSO1000Z/DS1000Z).
Return
Format
The query returns the sample rate in scientific notation.
Example
:ACQuire:SRATe? /*The query returns 2.000000e+09*/
