Programming the DC Source

Introduction

This chapter contains examples on how to program your dc source. Simple examples show you how to
program:
K output voltage and current functions
K internal and external triggers
K measurement functions
K the status and protection functions
NOTE: The examples in this chapter show which commands are used to perform a particular
function, but do not show the commands being used in any particular programming
environment.

Programming the Output

Power-on Initialization

When the dc source is first turned on, it wakes up with the output state set to OFF. In this state the
output voltage is set to 0. The following commands are given implicitly at power-on:
*RST
*CLS
*RST is a convenient way to program all parameters to a known state. Refer to the Common Commands
section in chapter 6 for a complete description of the above commands.

Enabling the Output

To enable all four outputs, use the command:
OUTP ON,(@1:4)
To enable only outputs 1 and 3 use the command.
OUTP ON,(@1,3)

Output Voltage

The output voltage is controlled with the VOLTage command. To set all four outputs to 5 volts, use:
VOLT 5,(@1:4)
The maximum output voltage that can be programmed can be queried with:
VOLT? MAX,(@<channel list>)
