Compatibility Language

The Agilent Series 664xA, 665xA, 667xA, 668xA, and 669xA Power Supplies are programatically compatible with the Agilent 603xA Series AutoRanging Power Supplies (ARPS). This means that you can program the Agilent 664xA, 665xA, 667xA, 668xA, and 669xA supplies over the GPIB using the ARPS commands. Software that you have written for the autoranging power supplies can also be adapted to program the above supplies.

Note

The Agilent 664xA, 665xA, 667xA, 668xA, 669xA serial link is not supported by ARPS

 

commands. You can use only a GPIB primary address for the power supply.

 

 

To switch from SCPI commands to ARPS commands (and vice versa), use the SYST:LANG command. This command is documented in "Chapter 3 - Language Dictionary".

Table B-1 summarizes the ARPS commands that program the supplies. You will need to refer to the Series 603xA power supply manual1 for complete information on the ARPS commands. Some of the ARPS commands are similar to SCPI commands, but others are unique to ARPS. For example, the ARPS FOLD commands have no function with the Series 664xA, 665xA, 667xA, 668xA, and 669xA supplies. Similarly, there are some SCPI commands that have no ARPS function.

Note

Parallel Polling:

 

When programmed for parallel polling and Compatibility Language, power supplies operating under the

 

Agilent BASIC system can "hang up" the GPIB when the system is turned on. This can occur under the

 

following conditions:

•The controller uses CS80 Protocol for an external disk drive (for example, the Agilent 9133D).

•The external disk drive and the power supply have the same select code and that code is 7 or less.

•The external disk drive and power supply addresses are binary complements of each other (e.g., 0 & 7, 1 & 6, etc.).

When the system is turned on, the power supply accesses the GPIB before the controller and prevents it from accessing the external disk drive. The solution is to change one of the GPIB addresses, or to ensure that the power supply is not turned on until after the controller has completed its selftest and has control of the GPIB.
