Models 707B and 708B 199BSwitching Matrix User's Manual

Section 6: Working with the Series 2400

707B-900-01 Rev. B / June 2013

6-3

Example 1: Individual commands for switch-measure

In this example, individual commands are sent to the Model 707B or 708B and SourceMeter
Instrument to perform switch closure and measure actions.

Example program code for the Model 2400

TSB and TSB Embedded cannot be used to control the Model 2400 SourceMeter instrument. You
are expected to send commands to the Model 2400 using a separate application development
environment, such as Microsoft

Visual Studio

or National Instruments LabVIEW™.

Send the following commands to configure the Model 2400 SourceMeter Instrument.
