Abstract
An acquisition apparatus for a test and measurement instrument including a splitter configured to split an input signal into a plurality of split signals, a plurality of oscillators, each oscillator configured to generate a periodic signal, a plurality of combiners, each combiner configured to combine an associated plurality of the periodic signals into an associated signal combination where at least one of the signal combinations is substantially non-periodic. The apparatus also includes a plurality of mixers, each mixer configured to mix an associated split signal and an associated signal combination into an associated mixed signal, a first digitizer configured to digitize an associated split signal, and a plurality of second digitizers, each second digitizer configured to digitize an associated mixed signal.
