ABSTRACT:
A printed circuit board tester for testing matched impedance test sites on a printed circuit board comprising an x-y prober having a first prober head and a second prober head above the printed circuit board connected to a time domain reflectometer by a coaxial test cable. A signal probe is attached to one of the prober heads. The test cable includes a signal wire which is electrically connected to the signal probe and includes a ground shield electrically connected to a ground shield extender positioned around the signal probe. A separate ground probe is connected to the second prober head and includes a ground spring for temporarily contacting the ground shield extender to transmit ground signals to the ground shield of the test cable.
