Variable Crosstalk Coupler

Applied with Artek’s unique technologies for analog signals as well as advanced electromagnetics, the VXC4000 series are designed as a Variable Crosstalk Coupler for high speed serial interface stress tests. It linearly controls the amount of crosstalk from the aggressor by 1,000 steps in its dynamic range. The differential transmission lines for both aggressor and victim are totally passive and DC coupled. The adjusted crosstalk amount is reliably repeatable and stable for secure test results. The control is done by PC remote via USB. The VXC4000 series are useful crosstalk coupler, applicable for various standard stress tests and compliance tests.
