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: The dc sources described in this manual can only be programmed using the SCPI
programming language.
The dc source may be remotely programmed via the GPIB bus. 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. Refer to chapters 6 and 7 for more information. Chapter 8
is a language dictionary of all SCPI commands that can be used to program the dc source.
