Select the Sampling Rate Units, Sampling Rate, and Current Range
Specify how often to make measurements during the scan by selecting one of the sampling rate units
shown in the following table and setting a value for the sampling rate. The acquired measurements
are stored in the active buffer of the instrument,
cvBuffer
. The buffer can hold a maximum of
100,000 readings.
The following table describes the available interval units and accompanying range of values.
Sampling rate unit
Description

regardless of how many cycles
10 to 10,000
points/cycle
The number of points acquired in each cycle
10 to 10,000
s/point
The number of seconds per each point
0.01 to 100
points/s
The number of points taken per second
0.01 to 100
To select the Sampling Rate Units:
