Noise figure analyzers operate through a programmable noise generator that is designed to supply a high level of white Gaussian noise. Some noise figure analyzers can be operated manually by way of panel controls: others can be managed remotely via a controller. The noise tester then emits Gaussian noise, random noise, and repeatable noise with very long repetition rates for simple problem identification.
Some applications for noise figure analyzers include electromagnetic susceptibility, system and component wireless testing, filter testing, CATV gain (tilt) alignment, GPS receivers, radar testing, jamming systems, image and spurious rejection tests, signal to noise measurement, and more. Advanced Test Equipment Rentals carries noise testers by leading manufacturers like NoiseCom, General Radio, Noiseken, and more.
