Abstract
An apparatus provides patterns for visually aiding an operator in determig the nature and noise environment of the incoming signal. A conventional signal receiver and an oscilloscope are coupled to a pair of phase detectors, a clock circuit, a reference circuit, and a timing circuit. The clock circuit synchronizes the operation of the receiver, reference circuit, and timing circuit. The phase detectors have pair of inputs and an output with the inputs of one detector being connected to the receiver and the reference circuit, and its output is connected to the Y deflection axis of the oscilloscope screen. The inputs of the other detector are connected to the receiver and the output of the reference circuit via a preselected analog time delay, and its output is connected to the X deflection axis of the oscilloscope screen. The output of the timing circuit is connected to the Z intensity axis of the oscilloscope screen for a preselected time duration to provide the capability to vary the intensity of a part of the screen such that patterns are generated on the oscilloscope screen representing the presence of some constituents and the inherent nature of the incoming signal which might include, the type of noise, the presence of doppler shift or CW interference, or drift of a component.
