1、Noise Source: This signal generator can produce noise to work as spectrum tracking source and interference source as well. 2、Reliable Use: Able to easily amplify the white noise output in the breakdown state using a special voltage regulator diode. 3、Simpler Work: Excess Noise Ratio, that is, the multiple of the thermal noise that the noise source exceeds the standard noise temperature T0. This refers to the poor signal strength when the spectrum is not connected to the noise source and after the noise source is connected. 4、Good Housing: Adopting high quality aluminium alloy material, has excellent durability and guarantees better protection. 5、Easy to Install: Comes with a light weight and a compact size, the simple installation can be quickly finished in minutes.
