Calibration secure state, calibration secure code and calibration message
From the remote interface, send the following command in sequence:
-CALibration:SECure:STATe OFF, <code>
NOTE: <code> refers to “003640” for model E3640A, "003641" for model E3641A, "003642" for model E3642A, "003643"
for model E3643A, "003644" for model E3644A, and "003645" for model E3645A. Applicable only if user has not changed
the model number from the default value.
