Interelectrode open and short circuit tester

摘要

A series of input pulses are applied to one terminal of an electron tube having at least two electrodes. As a result of interelectrode capacitance, the input pulses produce output pulses at the other electrodes, the output pulses having amplitudes which are substantially less than those of the input pulses. Level detection means is used to detect interelectrode open and short circuits by measuring the amplitudes of the output pulses.
