:CALibrate Subsystem

Use the :CALibrate subsystem to perform calibrations or confirm calibration status for N1000A mainframes and N1000A modules as well as N1092-series DCA-M modules. This subsystem corresponds to FlexDCA's Calibrations dialog shown in the following picture. Click on the tabs in this picture to learn about the different calibrations.

Calibration Flow Control Commands

Several FlexDCA/FlexRT calibration commands allow you to control the flow of a running calibration. These commands are equivalent to the Cancel, Continue, and Done? buttons that are displayed in the calibration dialogs:

• :CALibrate:CANCel,
• :CALibrate:CONTinue, and
• :CALibrate:SDONe

Example Command Sequence

The following commands are used for a typical vertical calibration. The :SDONe? query is used to detect when a portion of the calibration has completed. The :CONTinue command is used to dismiss dialogs that are displayed during a calibration. SLOT3 identifies a module that is installed in the right module bay.

The following commands are used for a typical vertical calibration.

:CALibrate:SLOT3:VERTical ENABled
:CALibrate:SLOT3:STARt
:CALibrate:SDONe?
:CALibrate:CONTinue    //  Dismiss the begin notice calibration dialog
:CALibrate:SDONe?
:CALibrate:CONTinue    //  Dismiss the disconnect notice dialog
:CALibrate:SDONe?
:CALibrate:CONTinue    //  Dismiss calibration complete dialog
