What is used for? A: noise source, generator noise, used tracking generator, jam source Q: what is the basic principle and how to use? A: used special voltage regulator tube, generator white noise and then amplifier. Directly replace tracking generator. Q: what is ENR? A: ENR (Excess Noise Ratio), noise sources over standard noise temperature T0 thermal noise. Here refers to the difference of no input noise source and input noise source signal level. colour: green Material: plastic size: 85*55*25mm Package Contents: 1 * module as picture show Only the above package content, other products are not included.
