The Agilent 53210A/53220A/53230A Calibration Procedures

Assembly-Level Service Guide 123

• Display shows:

– Cal Count shows the total number of times: (1) a successful

calibration step has been completed; (2) calibration data is

downloaded; (3) the Cal String or Secure Code is updated; (4) the

counter firmware is updated. It is not operator-modifiable and

rolls over at (2

-1). Since the unit is calibrated several times

during manufacture, the Cal Count will not be zero when shipped.

– Cal String shows the current calibration string. This string is

operator-modifiable, used to record such information as the date of

the last calibration, or by whom it was performed. The Calibration

String can not be entered from the front panel keys. It can only be

entered/updated using the remote SCPI command: CALibration

STRing. Refer to the Agilent 53210A/53220A/53230A SCPI

Programmer’s Reference for details of the command format.

– Secure Code displays either all dashes ( --- ) or an operator-

entered security code that has not yet been accepted by the

counter.

against calibration. (See step 2.)

8 If “Lock Cal” is displayed on a softkey, the counter is unlocked

and ready for calibration.
