Crosspoint Matrix Switching for Functional Test

Crosspoint matrix switches are one of the most flexible switching choices you can select for your next functional test system-essentially, a crosspoint matrix switch can connect virtually any test resource to virtually any test point on the DUT (Device Under Test). But like any selection you can make, there can be pros and cons in utilizing a crosspoint matrix: a test engineer needs to carefully weigh the specifications of the DUT to be tested in order to make the right switching choice for the test application being considered.
In this short video, we will explain how a matrix works, different ways to configure them, what questions to ask concerning the application and more. We will also compare building a large matrix with multiple switch matrices versus selecting a totally integrated switch matrix.

Very good info video. Thanks

How is the programmable switch connecting a column with a row technically realized? Is it a tri-state circuit?

[@Pickeringtest]

Hi Friedbert, tri-state does not really apply here. Tri-state is more relevant with logic switching with a high state low state and a high impedance floating state. We are just connecting a point or disconnecting a point. If you have additional questions, please email [e-mail] and we'd be happy to answer them.

@@Pickeringtest thanks a lot for your explanations. So, I guess you saying "Tri-state is more relevant with logic switching....", this refers to an Ethernet switch, right?
And for your product, when you say "We are just connecting a point or disconnecting a point". How is this done technically, do you use electromagnetic relays?
