Chapter 4 Remote Interface Reference

Simplified Programming Overview

This section gives an overview of the basic techniques used to program the

power supply over the remote interface. This section is only an overview and

does not give all of the details you will need to write your own application

programs. Refer to the remainder of this chapter and also chapter 6,

‘‘Application Programs’’, for more details and examples. Also refer to the

programming reference manual that came with your computer for details on

outputting command strings and entering data.

Using the APPLy Command

The

APPLy

command provides the most straightforward method to program

the power supply over the remote interface. For example, the following

statement executed from your computer will set the power supply to an output

of 3 V rated at 1 A:

‘‘

APPL 3.0, 1.0

’’

Using the Low-Level Commands

Although the

APPLy

command provides the most straightforward method to

program the power supply, the low-level commands give you more flexibility

to change individual parameters. For example, the following statements

executed from your computer will set the power supply to an output of 3 V

rated at 1 A:

‘‘

VOLT 3.0

’’

Set output voltage to 3.0 V

‘‘

CURR 1.0

’’

Set output current to 1.0 A
