Set Up Remote Communications; Set Up External Hardware Triggers; Connections For The Scpi Command Set - Keithley Interactive SourceMeter 2450 User Manual

Section 7: Measuring I-V characteristics of FETs
•
Cabling from the computer to the Model 2450 instruments depends on the command set you are
using:
•
For the SCPI command example, use two GPIB cables, two USB cables, or two ethernet cables
• For the TSP command example, use one GPIB cable, one USB cable, or one ethernet cable
Instructions for setting up the two Model 2450 instruments for this application are in the following
paragraphs.

Set up remote communications

You can run this application from any of the supported communication interfaces for the instrument
(GPIB, USB, or ethernet).
The following figure shows the rear-panel connection locations for the remote communication
interfaces. For additional information about how to set up remote communications, see
communication interfaces

Set up external hardware triggers

To enable synchronization between the two Model 2450 instruments for stepping and sweeping
voltages, connect the external triggers of each instrument to the other. The cabling you use depends
on Model 2450 programming command set you choose to control the test.

Connections for the SCPI command set

If you are using the SCPI command set, connect a DB-9 male-to-male cable between the digital I/O
connectors on the back of each of the instruments, as shown in the figure below.
For more detailed information about the digital I/O connector pins, see "Digital I/O" in the Model 2450
Reference Manual.
