Abstract
A system for quantitative measurement of pulse circuit stability parameters, such as pulse time, amplitude and duration, and frequency or phase of an RF source. The device is a video instrument and the input pulse is ordinarily a demodulated RF pulse from a system to be evaluated, and includes an analog conditioning section and a digital processing section allowing for an analog indication of RMS 'jitter.' Means are provided for sampling and converting all parameter variations to amplitude variations and for quantizing them to digital form. Digital signal processing such as FFT, MTI Cancelling circuits, etc., are provided, after which there is digital-to-analog conversion and RMS detection and indication. Thus the measurement effected may be thought of as based on the MTI residue resulting from transmitter pulse instabilities of the type aforementioned.
