Changing the Calibration Password
The factory default password is 0. You can change the password when the ac source is in calibration
mode (which requires you to enter the existing password). Proceed as follows:
Action Display
1.
Begin by pressing Shift Cal and scrolling to the CAL ON command.
CAL ON 0.0
2.
Enter the existing password from Entry keypad and press Enter
3.
Press Shift Cal and scroll to the CAL PASS command.
CAL:PASS 0
4. Enter the new password from the keypad. You can use any number with up
to six digits and an optional decimal point. If you want the calibration
function to operate without requiring any password, change the password to
0 (zero).
NOTE: If you want the calibration function to operate without requiring any password, change
the password to 0 (zero).
Calibration Error Messages
Errors that can occur during calibration are shown in the following table.
Table B-5. GPIB Calibration Error Messages
Error Meaning
401 CAL switch prevents calibration (This is a hardware disable, see the ac source Service Manual.)
402 CAL password is incorrect
403 CAL not enabled
404 Computed readback cal constants are incorrect
405 Computed programming cal constants are incorrect
406 Incorrect sequence of calibration commands
Calibration Over the GPIB
You can calibrate the ac source by using SCPI commands within your controller programming
statements. Be sure you are familiar with calibration from the front panel before you calibrate from a
controller. Each front panel calibration command has a corresponding SCPI command.
The SCPI calibration commands are explained in Chapter 3 of the ac source Programming Guide.
Calibration error messages that can occur during GPIB calibration are shown in table B-3.
Agilent Calibration Program Listing
Figure B-2, Sheets 1 through 3, lists the calibration program. This program can be run on any controller
operating under Agilent BASIC. The assumed power supply address is 705 and calibration password is 0.
If required, change these parameters in the appropriate statements.
