Front Panel Controls
The front panel has both rotary and keypad controls for setting the output voltage and current. The panel
display provides digital readouts of a number of output measurements. Annunciators display the
operating status of the dc source. System keys let you perform system functions such as setting the GPIB
address and recalling operating states. Front panel Function keys access the dc source function menus.
Front panel Entry keys let you select and enter parameter values. Refer to chapter 5 for a complete
description of the front panel controls.
Remote Programming
NOTE: When shipped, all dc sources are set to the SCPI programming language.
On Agilent 66111A and Agilent 66311B/D units you can change the programming
language from SCPI to COMPatibility language. Press the front panel Address key, use
ó to scroll to the LANG command, press to select COMP, then press Enter. The
language setting is saved in non-volatile memory.
The dc source may be remotely programmed via the GPIB bus, and on Agilent 66111A and 66311B/D
units, from an RS-232 serial port. GPIB programming is with SCPI commands (Standard Commands for
Programmable Instruments), which make dc source programs compatible with those of other GPIB
instruments. Dc source status registers allow remote monitoring of a wide variety of dc source operating
conditions. A Compatibility language mode is also included on Agilent 66311A and 66311B/D units to
make the dc source compatible with the Agilent 6632A, 6633A, and 6634A Series dc power supplies
(refer to appendix E). Note that the compatibility features of this unit are limited to the features that were
originally available on Agilent 6632A, 6633A, and 6634A units.
