Calibration
You need to execute calibration to eliminate error elements related to measurement and
perform accurate measurement.
Performing a Calibration (Obtaining the Calibration Coefficients)
Selecting a Calibration Kit
To select a calibration kit, use the following command:
:SENS{1-4}:CORR:COLL:CKIT on page 375
Selecting a Calibration Type
The calibration coefficients are calculated based on the selected calibration type. Before
you can calculate the calibration coefficients, therefore, you must select the appropriate
calibration type using the following command.
To check the currently selected calibration type, use the following command:
:SENS{1-4}:CORR:COLL:METH:TYPE? on page 405
Measuring the Calibration Data
To measure the calibration data, use the following command:
NOTE You cannot run more than one of the commands listed above at a time; if you issue another
command before the currently running command completes successfully, the current
command will be aborted. When you write a program that issues multiple calibration
commands in series, therefore, you should use the *OPC? command on page 198
command or some other means to ensure that no command is executed before the
Calibration type Command
