B - Verification and Calibration

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).

Meaning

CAL switch prevents calibration (This is a hardware disable, see the ac source Service Manual.) CAL password is incorrect

CAL not enabled

Computed readback cal constants are incorrect

Computed programming cal constants are incorrect

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.
