Overview
Agilent N4371A RIN Measurement System ▲ Accurate, high-speed and easy measurements of RIN frequency characteristics ▲ Reduced uncertainty by using Agilent original characterization technique (patent pending) ▲ High-speed measurement (5 seconds or less for 20 GHz span, 2000 point, 10 average) ▲ Analysis on multiple traces by various markers Agilent provides accurate, high-speed and easy-to-use spectral RIN measurement system by combination of a sensitive, low-noise optical receiver, a industry-standard x-series spectrum analyzer and a digital multi-meter.
RIN (Relative Intensity Noise) is a parameter representing temporal intensity fluctuations of a laser signal and 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 and analog optical transmission systems.
N4371A Agilent RIN measurement system provides accurate RIN measurements with a specially developed characterization technique (patent pending) for the photoelectric frequency response of the entire system.
Agilent RIN measurement system also reduces uncertainties by removing the interference by thermal noise and shot noise precisely.
The measurement speed of N4371A RIN measurement system is very fast by special control of the spectrum analyzer.
The measurement time is less than 5 seconds with the condition of a 20 GHz www.

com frequency span, 2,000 frequency points and 10 times average.
The high-speed measurement enables a real-time observation of RIN frequency characteristics with varying parameters of the DUT.
The user interface of N4371A RIN measurement system shown in figure 2 is easily accessible from the spectrum analyzer display.
The user interface provides functions of displaying up to 5 traces, placing up to 5 markers and searching minimum or maximum RIN values in specific frequency range.
