Abstract
A waveform translator in which the frequency spectrum of a repetitive non band limited input signal is translated to an equivalent frequency spectrum which is harmonically related to a fixed reference frequency. In the waveform translator a synthesized source generator and a synthesized receive generator are made coherent. The source generator drives a DUT, and the receive generator coupled to a sampler, samples the DUT to produce a non band limited difference signal harmonically related to the fixed reference frequency. The difference signal is digitized in an analog to digital converter which is clocked at the reference frequency and produces a predetermined integer number of data points per cycle corresponding to the input signal. A computer is coupled to the waveform translator for DC to 75 GHz oscillography.
