N4371A,N4371A 測(cè)試RIN,N4371ARIN測(cè)試 N4371A Relative-Intensity-Noise (RIN) Solution RIN測(cè)量系統(tǒng) 主要特性與技術(shù)指標(biāo) Sensitivity -160dB/Hz@0dBm (typ.） （@1310nm, 1550nm） Wavelength range 1265 nm - 1625 nm Frequency range 10MHz to 6.7GHz/20GHz 描述 RIN (Relative Intensity Noise) is a parameter representing temporal fluctuations of intensity of a laser signal.is used as an evaluation index of the noise characteristic of the laser devices. RIN is an indispensable item for indicating the signal quality of both digital.analog optical transmission systems. N4371A Keysight RIN measurement system provides accurate RIN measurements with a specially developed calibration technique (patent pending) for the photoelectric frequency response of the entire system. Keysight RIN measurement system also reduces uncertainties by removing the interference by thermal noise.shot noise precisely. Benefits Accurate, high-speed.easy measurements of RIN frequency characteristics Reduced uncertainty by using Keysight original calibration technique (patent pending) High-speed measurement (5 seconds.less for 20 GHz span, 2000 point, 10 average) Analysis on multiple traces by various markers
