Abstract:
A system for generating a repetitive test output signal and measuring a repetitive test input signal, comprising:a) a reference generator for producing a plurality of reference signals harmonically related to a specific reference frequency;b) a plurality of synthesizers with means responsive to said plurality of reference signals to generate and output a plurality of harmonically interrelated signals at a source repetition rate, and with means responsive to said plurality of reference signals and to said repetitive test input signal to output a plurality of harmonically interrelated signals at a receive repetition rate such that the receive repetition rate is set by calculating a first quotient by dividing the frequency of said repetitive test input signal by a value set according to a predetermined frequency, calculating a second quotient by dividing said specific reference frequency by a predetermined integer, and adding said first quotient and said second quotient;c) a sampler responsive to each of said plurality of harmonically interrelated signals at the receive repetition rate, and responsive to a plurality of frequency components of said repetitive test input signal to output a plurality of harmonically interrelated difference signals;d) an analog to digital conversion means responsive to one of said reference signals to digitize said plurality of harmonically interrelated difference signals and to output a digitized waveform corresponding to said repetitive test input signal.
