Anritsu S332D Sequence Site Master Calibration Control Byte #13 0Dh, Site Master Returns 2 bytes

Sequence Site Master Calibration – Control Byte #13 (0Dh)

Description: Initiates a calibration step. The Site Master must be calibrated to give accurate measurements.

The command sequence must be sent in correct order. i.e. Open -> Short -> Load. You can also abort the calibration by command – “Abort” before the command - “Load” is sent. Once command - “Load” is sent, calibration is completed, and the old calibration data is lost.

The unit under test returns #255(FFh) upon receiving the command, and return #240 (F0h) when the calibration of the connected component is completed, then waits for further commands to complete the whole calibration process.

This command is designed to be executed step by step: open, short, load. Issuing any other command during this command sequence will cause undesired results.
