3 - Troubleshooting

Initialization

The dc power supply's GPIB address and model number as well as other constants which are required to program and calibrate the supply are stored in a EEPROM on the A2 Interface board. The Interface board also contains references and other components that will affect the alignment of the supply. If the Interface board is replaced, the supply must be reinitialized and calibrated. To initialize the power supply:

a.Enable the Calibration mode

b.Simultaneously depress the "0" and "9” keys.

c.Using the Up/Down arrows select the appropriate model number

d.Press "Enter"

The dc power supply will go through the turn-on self test sequence. It is now re-initialized and must be calibrated. See Appendix A of the User’s Guide for the calibration procedure.

ROM Upgrade

Identifying the Firmware

You can use the *IDN? query to identify the revision of the supply's firmware. The query will readback the revisions of the Primary Interface ROM located on the A2 Interface board. The manufacturer and model number of the supply are also returned. The following is a sample program:

10 ALLOCATE L$[52]

20OUTPUT 705;"*IDN?"

30ENTER 705;L$

40DISP L$

50END

The computer will display the manufacturer's name, the model number, a "0," and then the firmware revision. Example: "AGILENT TECHNOLOGIES,66332A,0,A.00.01". The revision level of the ROM can also be found on the label affixed to the physical IC chip itself.

Upgrade Procedure

If the Interface board ROM is upgraded you can re-initialize the supply without affecting the calibration.

a.Enable the Calibration mode.

b.Simultaneously depress the "0" and "9" keys. EEINIT <model> will be displayed.

c.Using the Up/Down annunciator keys select ROMUPD <model>.

d.Using the Up/Down arrows select the appropriate model number.

e.Press "Enter".

The supply will go through the turn-on self test sequence and return to the power supply metering mode.
