An edge connector for connecting a conductor run on an edge region of a first circuit board to a conductor run of a second circuit board comprises a plate of dielectric material. The plate has a generally U-shaped portion, with the two limbs of the U defining a slot therebetween. The plate of dielectric material may be attached to the second circuit board in a position such that an edge region of the first circuit board may be received in the slot. A signal conductor is adhered to one main face of the plate of dielectric material and has two end portions. One end portion of the signal conductor projects from one of the limbs of the U into the slot for engaging a conductor run on the edge region of the first board, and the other end portion projects from the plate at a location remote from the slot for contacting a conductor run of the second board.

A dual channel time domain reflectometer includes a pair of input lines connected at respective nodes to a reference flat current pulse generator and a traveling wave sampling gate, respectively. The sampling gates are actuated by a balanced strobe generator which includes a waveguide coupler for coupling a high amplitude fast rise time pulse to each of the gates simultaneously. Pulses of requisite amplitude and shape are generated by a circuit responsive to a strobe trigger input which drives a step recovery diode.

A contact device comprises a resiliently deformable member having two opposite surface regions, and strips of conductive material bonded to the deformable member at one of its two opposite surface regions. The strips of conductive material are of substantially uniform width, substantially parallel to each other and substantially uniformly spaced from each other. The width and spacing of the strips are less than the width and spacing of the terminal areas of the conductor runs that are to be connected by means of the contact device, so that each terminal area contacts at least two strips of the contact device.
