The NC520 from Noisecom is a Noise Source that operates from 200 kHz to 5 GHz. It produces white gaussian noise with an output power of more than 25 dB ENR (-143 dBm/Hz) and has a crest factor of 5:1. This noise source contains all bias circuits and requires no external components. It has extremely flat output power versus frequency characteristic which is insensitive to temperature and voltage variations. The noise source requires a DC supply of 5 V and consumes less than 30 mA of current. It is available in a surface-mount package that measures 0.75 x 0.75 x 0.17 inches and is ideal for built-in test equipment (BITE), signal strength meters for cellular, PCS & CATV, calibrators, spectrum analyzers, radar warning receivers (RWR), Dither A/D quantization error and gain-bandwidth product testing applications.
