Introduction To Remote Operation

The following paragraphs explain the fundamentals of operating the supply remotely from a computer. Only a few commonly used programming commands will be discussed. Refer to Chapter 5 for a detailed description of all the commands. The intent of this discussion is to help first time users to quickly become familiar with operating their supply from a computer.

The programming examples that follow assume that a computer is connected to the GP-IB connector on the rear of your supply (see Chapter 2), power is applied, and loads are not connected to any of the supply’s outputs. The examples used are primarily for Agilent Series 200 computers using Agilent BASIC language. Read the manuals for your particular computer to find out which statements you must use.

Enter/Output Statements

The programming statements you use to operate your supply from remote depend on your computer and its language. In particular, you need to know the statements your computer uses to output and enter information. For example, the Agilent BASIC language statement that addresses the power supply to listen and sends the command to the power supply is:
