Abstract
An electrostatic discharge testing device employs magnetic reed relays in a switching array for selectively routing high-voltage, fast rise-time signals. The contacts of the reed relays are copper plated to minimize skin effect and thus decrease rise-time. Interposed between the glass enclosure and the magnetic coil of each reed relay is a metal-plated dielectric sheet formed in a tube with the plated side facing out. The plating at each end of the tube is connected to a ground reference voltage via a resistor.
