Abstract :
A periodically recurrent high-frequency time axis generator with return trace removal is described. The theoretical nonlinearity is less than one per cent. The apparatus is capable of tracing out one cycle of a thirty-megacycle wave. The wave form of a conventional high-frequency oscillator is altered by means of a high vacuum rectifier circuit to obtain the required sweep voltage wave. Return trace removal is accomplished by biasing the control grid of the cathode-ray tube to cutoff over the return trace portion of the sweep cycle.
