Keithley 6430 Quick Results Guide

Model 6430 Sub-Femtoamp
Remote SourceMeter
Quick Results Guide
Introduction
This guide is designed to familiarize users with fundamental operation (front panel and
remote) of the Keithley Model 6430 Sub-Femtoamp Remote SourceMeter. For
comprehensive information on all aspects of SourceMeter operation, refer to the Model
6430 SourceMeter Instruction Manual.
Operation information in this guide is divided into three parts: (1) Fundamental source-
measure operations, (2) Settings to optimize performance, and (3) Features to enhance
DUT testing. This format allows a new user to easily progress from basic operation to
more complex procedures.
Remote command programming - For the various SourceMeter operating modes
covered in this guide, the related SCPI commands for remote operation are summarized in
tables. Most commands have a query form. For example, :OUTPut ON turns the output
on, while :OUTPut? requests the present state of the output. Note that the SourceMeter
must be addressed to talk after sending a query command.
For operations where command sequence is important, programming examples are
provided. The exact programming syntax will depend on the test program language.
