Quick Reference 1

Output On/Off sequencing A turn-on/turn-off delay capability for each output allows output on/off sequencing.

Remote voltage sensing

Two remote sensing terminals are provided for each output. When shipped,

 

the remote sense jumpers are included in a separate bag. See Chapter 2.

Voltage and current

All power modules can measure their own output voltage and current.

protection. Over-voltage and over-current protection are programmable.

 

When activated, the protection circuits cause the voltage to go to zero, the

 

output to be disabled, and the protection status to be reported.

System Features

SCPI language

The instrument is compatible with the Standard Commands for

 

Programmable Instruments (SCPI).

Choice of three interfaces GPIB (IEEE-488), LAN, and USB remote programming interfaces are built in.

Front panel I/O setup Menus let you set up GPIB and LAN parameters from the front panel. Refer to Chapter 3 for details.

Built-in Web server

A built-in Web server lets you control the instrument directly from an

 

internet browser on your computer. Refer to Chapter 3 for details.

Real-time status

The front panel indicates the status of each output. It also indicates when

information

a protection shut-down has occurred.

Module identification

Each module has identifying data stored in non-volatile memory.

 

Information includes model number, serial number, and options. This

 

information can be displayed on the front panel.
