High-fidelity electrical interface connections for your ATE

Better electrical interface performance is required to keep pace with more stringent requirements of testing high-performance devices. These improvements also are necessary to minimize yield lost to marginal signal integrity while testing instruments with performance requirements that are becoming more stringent.

Your test results improve when you use the right interface, meticulously designed, properly manufactured and tested.
