Q: what is this? what used?
A: noise source, generator noise, used tracking generator, jam source
Q: What is the basic principle. how to use?
A: used special voltage regulator tube, generator white noise and then amplifiler.
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 soucrce signal level
Packing list:
1 x Noise Source
