Feature: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.Specification:Item Type: Noise Signal GeneratorModel: XR-104Material: Aluminium AlloyColour: SilverPower Supply: DC12V 1APower Adapter: US Plug 100-240V 50/60HzOutput Interface: SMAReference ENR: 0.1G/60DB 0.5G/55DB 1G/52DB 1.5G/48DB 2G/38DB 2.5G/30DB 3G/27DB 3.5G/20DB. .Package List:1 x Noise Signal Generator1 x Power Adapter
