Method Of Measuring Noise Figure Using Arbitrary Waveforms

Abstract:
Noise figure of a device under test (“DUT”) is measured using a programmable RF source and a receiver, such as a spectrum analyzer. The programmable RF source is operated to produce pseudonoise, such as white Gaussian noise (“WGN”), as the hot noise source. Turning the programmable RF source off provides a good termination to the DUT, which is used as a cold noise source. Alternatively, The pseudonoise produced by the programmable RF source is more predictable in amplitude and frequency hopping than true noise, resulting in faster calibration and measurement.
