Noisecom  NC346 噪声源模块

Broadband Calibrated Noise sources for Noise figure measurements

The Noisecom NC346 Series is designed for precision noise figure measurement applications. The VSWR has been improved, reducing multiple reflections of the test signals and significantly increasing the measurement accuracy of most noise figure set-ups.

The NC346 Series noise sources have broadband coverage and extremely good temperature and voltage stability, for the finest noise figure meter-compatible laboratory standards. Outputs of 6, 15.5 and 22dB ENR are available, allowing the units to accurately measure noise figures up to 20, 30 and 36 dB respectively.
