GJ-2490双通道智能化光功率计

Dual Channel Optical Power Meter With Intellectual Faculties GJ--2490

GJ-2490是具有两个通道的光功率计,可用于光纤通信、测量系统的高精度、高稳定测量。它的高灵敏性使它有能力测量-90dBm的0.85μm和1.3μm波长的光功率。可测光功率的波长范围为0.4μm到1.7μm。基本测量系统由主机和两个探头组成。根据不同的光功率电平和波长范围可从四个探头中选择任意两个使用。该仪器具有两个独立的可同时显示的通道,两个通道间可进行数据处理,并具有数据存贮、波长校正、平均值显示、自动调零等功能。该仪器使用Z80-CPU作为核心控制元件,实现了光功率计的智能化。测量量程的扩展和切换取决于放大器放大和衰减倍数的不同组合。

The GJ-2490 is an optical power meter with dual channelsdesigned for use in optical fiber communications and measures systems.Its high sensitivity gives it the capability to measure extremely lowlevel power down to -90dBm both at the 0. 85μm and 1. 3μm wavelengthWavelength settings can be made over a range of 0. 4 to 1. 7μm. Thebasic measurement system consists of the mainframe and two sensorunits selecting from four sensor units which are available (optionally)to suit specific applications of different optical power level andwavelength. This meter has dual independent channel with display atthe same time. It also can conduct the manage of testing data betweendual channel. It has many features, such as data store, wavelengthcalibration, average display, automatic offset, etc. The metercompleted intelletual faculties by useing Z80-CPU as a center controlelement. The expansion of measure range and its automatic switchdepend on the different composition of amplification and attenuationof amplifier.
