Abstract: The design and operation of an instrument for the oscilloscopic observation of frequency fluctuations in the output of sound reproducing equipment is described. The instrument indicates the instantaneous rather than the average or root-mean-square frequency deviation for test frequencies between 500 cps and 20 kc. A phase-locked loop permits automatic following of frequency drift over ±20% of the test frequency.
