Abstract
Embodiments of the present disclosure provide a system, method, and program product to test phase noise. The system may include a frequency converter for reducing a frequency of a portion of the output signal to a transformable frequency, a bandpass filter electrically coupled to the frequency converter for filtering the portion of the output signal the transformable frequency using a predetermined bandwidth, and waveform analysis module for receiving the filtered signal. The frequency converter may include a variable electronic oscillator (EO) configured to select one portion of the output signal. The waveform analysis module applies a Fast Fourier Transform (FFT) to each filtered portion of the output signal, and combines them to yield a total FFT for the output signal.
