A portable high-frequency oscillograph for television is described by which a square-wave (100-kilocycle) response may be viewed as a dotted wave and readily recorded as a series of readings. The dots are spaced at 1/30(or 1/20-) microsecond intervals. No electrical connection is required between the oscillograph and the square-wave generator other than that established through the apparatus under test since the synchronous sweep and timing dots are derived from the square-wave response of the apparatus. Circuit diagrams of the square-wave generator and square-wave oscillograph are given.
