Abstract: A device for measuring phase noise, including a sampler to sample an input signal, an input filter to receive an input from the sampler, a noise generator to generate a noise signal, a combiner to receive input from, respectively, the input filter and the noise generator, the combiner to output an integrated noise output measurement. The input filter may operate in either the time domain or the frequency domain. The noise generate may generate a noise signal based on the sampler output, or may generate a noise estimate value based on the sampler output.
