Automated test equipment for high-speed testing of devices under test (DUTs) includes a tester channel circuit generating a high-speed electrical test signal applied to the signal input terminal of each DUT, and a contacter board in physical and electrical contact with the DUTs. The contacter board has a high-speed signal transmission channel including (1) an electrical contact at which the high-speed electrical test signal is received, (2) conductive etch extending from the electrical contact to isolation areas each adjacent to the signal input terminal of a respective DUT, and (3) an embedded series isolation resistor formed on an inner layer of the contacter board at a respective isolation area forming a connection between the conductive etch and the adjacent signal input terminal of the respective DUT.
