SU4300 Series

SU4300 Noise Source


In the communication system, the measurement equipment with high performance should be prepared in order to ensure the working stability of facilities. SU4300 Series Noise Source is one of them. It is used to simulate the noise of satellite communications to get an appropriate SNR to measure the miscode ratio of intermediate frequency modem. Noise source is not only used in satellite communications to simulate the Gauss white noise in the satellite circuitry, but also used in the microwave communication and scatter communication. The present SU4300 Series noise source uses the heat noise generated by the intermediate amplifier as the noise source because it is of the characteristics of Gauss white noise.
