To set the maximum number of the measurement data segments stored in the volatile memory, use the following command:
The number of data segments captured per measurement cycle is Param × Nop. Accordingly, when you want to capture the measurement data for Times cycles, you must set the maximum number to Param × Nop × Times. Param and Nop represents the following:
Param The number of measurement items currently displayed on screen. Each measurement item can be one of measurement parameters 1 through 4, the results of test signal current/voltage level monitoring, or the result of Rdc measurement.
Nop The number of measurement points per measurement cycle. The number should be “1” for single-point measurement or, for list measurement, the number of points defined in the active table.
You can begin capturing the measurement data for statistical analysis by issuing the command shown below. Once you have issued the command, each measured value (for measurement parameters 1 through 4, test signal current/voltage level monitoring, or Rdc measurement) is stored in the volatile memory (RAM) provided that the measured value is currently shown on screen.
If previously captured data is still in the volatile memory and you issue the command, the instrument clears the existing data and then begins capturing new data.
The instrument finishes capturing the data when:
The number of captured data segments reaches the maximum number.
The :CALC:EXAM:GET? command starts another session of statistical analysis.
To check the progress of data capture, examine the number of data segments stored in the volatile memory (RAM) by issuing the following command:
To save the measurement data for statistical analysis from the volatile memory to a file, use the following command. See Saving data to a file for more information.
