Introduction
This power supply is programatically compatible with the Agilent 603xA Series AutoRanging Power Supplies (ARPS).
This means that you can program this power supply over the GPIB using the ARPS commands. Software that you have
written for the autoranging power supplies can also be adapted to program this power supply.
Note The Agilent E4356A Power supply’s 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 7.
Table G-1 summarizes the ARPS commands that program the supplies. You will need to refer to the Series 603xA power
supply manual (see Table 1-4) for complete information on the ARPS commands. Some of the ARPS commands are
similax to SCPI commands, but others are unique to ARPS. For example, the ARPS FOLD commands have no function
with the Agilent E4356A power supplies. Similarly, there are some SCPI commands that have no ARPS function.
Parallel Polling
When programmed for parallel polling and Compatibilty 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.
