In this Book

Specific chapters in this manual contain the following information:

Quick Reference – Chapter 1 is a quick reference section that helps you quickly become familiar with your Agilent N6700 Modular Power System. It describes the differences between the various modules in the power system.

Installation – Chapter 2 describes how to install your power system. It describes how to connect various loads to the output. It discusses remote sensing as well as parallel and series operation.

Getting Started – Chapter 3 describes how to set the voltage, current, over-voltage protection, and turn on the output. It also describes how to configure the remote interface.

Operating the Power System – Chapter 4 describes how to use the advanced features of the power system using the front panel menus and the corresponding SCPI commands.

Specifications – Appendix A describes specifications and supplemental characteristics.

Using the Digital Port – Appendix B describes how to configure and use the digital port on the back of the instrument.

Power Allocation – Appendix C describes the power allocation function, which applies to power system in which the combined ratings of the power modules exceed the power rating of the mainframe.

Output On/Off Synchronization – Appendix D discusses output on/off synchronization, which lets you accurately synchronize output turn-on sequences across multiple mainframes.

For complete details on the SCPI (Standard Commands for

Programmable Instruments) commands, refer to the Programmer’s

Reference Help file included on the Agilent N6700 Product Reference

CD. This CD-ROM is shipped along with your instrument.
