Digitize voltage: DIGitize:VOLTage
<n>
1,000 to 1,000,000 readings per second
Details
The sample rate determines how fast the Model 2461 acquires a digitized reading.
Set the sample rate before setting the aperture. If the aperture setting is too high for the selected
sample rate, it is automatically adjusted to the highest aperture that can be used with the sample rate.
Example
DIG:FUNC "CURR"
DIG:CURR:SRATE 1000000
DIG:CURR:APER AUTO
DIG:COUN 10
MEAS:DIG?
Set the digitize function to measure current.
Set the sample rate to 1,000,000, with a
count of 10, and automatic aperture.
Make a digitize measurement.
