About the Agilent 53210A/53220A/53230A Calibration Menu
Assembly-Level Service Guide 97
A calibration security code feature allows you to enter a security code
(electronic key) to prevent accidental or unauthorized calibrations of the
counter. The security code is set to AT53210A, AT53220A or AT53230A
(corresponding to the model) when the counter is shipped from the factory.
If you change, and then forget, your security code, you can reset the
security code to a blank code by resetting all of the non-volatile memory to
a default state. (Refer to the Procedure “Resetting the Security Code to a
Null” on page 141 .) Then you can enter a new code.
The Calibration menu allows you to:
• (Secure Code) - View/change the calibration security status of the
counter (Locked/Unlocked), or change/edit the secure password.
• (Lock Cal) - Secures against calibration by entering the displayed
security code while the counter is unlocked.
• (Unlock Cal) - Unlocks the counter for a new calibration by entering
the correct security code while the counter is locked.
• (Perform Cal) - Initiates the counter’s calibration routines, which
allow you to:
– (Cal Step) - Select the type of calibration (frequency or voltage):
(Osc) - Input the RF frequency for Channel 1 or Channel 2
frequency calibration.
(Positive Voltage) - Calibrate, with an operator applied
positive reference voltage, the internal DACs.
(Negative Voltage) - Calibrate, with an operator applied
negative reference voltage, the internal DACs.
(uWave) - Input the calibration frequencies for the 6 GHz
or 15 GHz microwave channel (Options 106 or 115).
(Perform Cal Step) - Initiate the selected calibration step.
• (Measure Temp) - Reads and displays the current temperature and
also the temperature of the instrument during the last Auto-Cal.
• (Auto Cal) - Performs an automatic calibration of the internal circuits
of the counter. Does not require any external inputs. Same as the IEE-
488.2 command *CAL?.
