1. Apparatus for measuring the effective electrical resistance of an unknown element while subjected to repetitive high voltage pulses comprising, in combination, means for applying repetitive short duration high voltage pulses to the unknown element, means for generating a first analog voltage proportional to the voltage across the unknown element, means for generating a second analog voltage proportional to the current through the unknown element, first means responsive to a trigger signal for temporarily storing such first analog voltage, second means responsive to a trigger signal for temporarily storing such second analog voltage, means responsive to said high voltage applying means for simultaneously applying trigger signals to said first and second storing means at a predetermined point in each high voltage pulse applied to the unknown element, first means for digitizing the first analog voltage stored in said first storing means, second means for digitizing the second analog voltage stored in said second storing means, means for triggering both of said first and second digitizing means a predetermined time after new analog voltages are stored in said first and second storage means, means responsive to the digitized outputs from said first and second digitizing means for generating digital resistance data corresponding to the resistance of the unknown element, and display means responsive to such generated digital resistance data for indicating the resistance of the unknown element.
