作为表征光波系统和远件特性的一种宽带灵敏的O/E转换器，11982A把一个PIN光检测器同一个低噪声的dc耦合前置放大器相结合，就成为通用前端。它覆盖了从1200nm到1600nm的波长和从dc到15GHz的带宽。由于具有300V/W的变换增益和0.05%的校正频率响应测量的仪器专用数据的定标图。 11982A同83840系列数字通信分析仪相结合,可以进行光眼图和脉冲响应测量.利用这些测量结果,可以检验光和光电元件以及光系统的等级性能. 11982A可以与频谱分析仪一起使用,以显示作为频率函数的光调制功率.幅度调制,畸变和激光强度噪声也可以测量.选件001存储卡为8590E系列编制的频率响应校正程序,以便方便,的测量高达22GHz光波.利用这种转换器与11980A干涉仪配合,您可以测量单线激光器的线宽(借助于一个调制光源),啁啾声和频率调制.
As a broadband sensitive O/E converter that characterizes the characteristics of lightwave systems and remote parts, the 11982A combines a PIN photodetector with a low-noise dc-coupled preamplifier to become a universal front end. It covers the wavelength from 1200nm to 1600nm and the bandwidth from dc to 15GHz. Because of the conversion gain of 300V/W and the correction frequency response of 0.05%, it is a calibration chart of instrument-specific data for measurement. The 11982A can be combined with the 83840 series digital communication analyzer to perform optical eye diagram and impulse response measurements. Using these measurement results, you can verify the level performance of light and optoelectronic components and optical systems. 11982A can be used with a spectrum analyzer to display Optical modulation power as a function of frequency. Amplitude modulation, distortion and laser intensity noise can also be measured. Option 001 memory card is a frequency response correction program compiled for the 8590E series for convenient measurement of light waves up to 22GHz. Use this converter with With the 11980A interferometer, you can measure the linewidth of a single-line laser (with the aid of a modulated light source), chirp and frequency modulation.
