This article describes an adjustable delay line for delaying pulses or high frequency electrical signals. The delay line features use of a delay element in the form of a helical signal conductor imbedded in an insulating layer which is positioned in the groove of a helically grooved rotatable metallic cylinder. The line also features a signal pick off probe mounted for mechanical movement relative to the signal conductor and along the signal conductor's length to provide variable delay of an applied signal.
