Acquire Commands
SRATe (Sample RATe)
SRATe (Sample RATe)
Command :ACQuire:SRATe {AUTO | MAX | <rate>}
The :ACQuire:SRATe command sets the acquisition sampling rate for real time
and peak detect sampling modes. If the oscilloscope is in the equivalent time
sampling mode, the SRATe command has no effect on the sampling rate.
However, if you change the sampling mode to one of the real time sampling
modes the control will show the new value.
AUTO
The AUTO rate allows the oscilloscope to select a sample rate that best
accommodates the selected memory depth and sweep speed.
MAX
The MAX rate enables the oscilloscope to select maximum available sample rate.
<rate>
A real number representing the sample rate. You can send any value, but the
value is rounded to the next fastest sample rate.
Interaction between :ACQuire:SRATe and :ACQuire:POINts
If you assign a sample rate value with :ACQuire:SRATe or a points value using
:ACQuire:POINts the following interactions will occur. “Manual” means you are
setting a non-AUTO value for SRATe or POINts.

Available Sample Rate Values (in Sa/s)
Example This example sets the sample rate to 250 MSa/s.
