Abstract : The patent describes a testing device for measuring phase shift and amplitude changes in an amplifier. A frequency synthesizer provides a sine wave through first and second channels with the amplifier being connected in the first channel. The outputs from the first and second channels are applied to a computer for analysis. The computer is programmed to calculate the phase angles for the waveforms. The difference in these phase angles is the phase shift of the amplifier under test, and this difference is presented in a readout device.
