Introduction
This application example demonstrates how to use the DMM6500 to perform benchtop binning
operations. It uses the trigger model and digital I/O to control external component-handling devices.
The DMM6500 can do simple pass-or-fail testing as well as grading and sorting. Grading resistors is a
common application that is done by monitoring multiple limits until the first failure. Binning resistors is
also common, but unlike grading, binning involves monitoring limits until the first pass is received.
Equipment required
• One DMM6500
• One computer set up for communication with the instrument
• One device or component to be tested
Device connections
This example application uses a DMM6500 to perform benchtop binning operations. Output signals
(grading results) are sent from the instrument to the component handler, which bins the devices.
The figure below shows the rear-panel connections from the DMM6500 to the test fixture and the
digital lines to the component handler. The optional GPIB communication card connects the controller
and the component handler.
Digital lines and GPIB communications require the KTTI-GPIB communications accessory card.
