ANDO AQ2140光万用表是作为通用的光学测试仪器。
它可以用于广泛的应用，从研发到光纤和组件制造，以及建设和维护。
这种模块化系统提供了高精度，强大的功能和高速测量，使它成为通用和集成应用的*的工具之一。
特征传感器单元高精度测量精度保证在参考条件下的2.5%。
波长范围宽、动态范围宽波段从400到1870nm，并提供损耗的测量动态范围100dB以上。（这取决于传感器。）
低偏振相关的aq2733和aq2734传感器单元实现低偏振0.02dbp-p或更少的依赖。
为aq2734传感器单元采用光电二极管1300 1800nm平波长灵敏度1650nm频段支持，准确测量在1650nm以及。
光源装置的高稳定性的LD单元有一个内部的隔离，保持光输出水平稳定在±0.003db。
光功率衰减函数的光功率可在0.1 dB步6.0db下降。用于各种连接器的各种光纤连接器就可以通过交换的通用连接器适配器支持（aq4214除外）。
回波损耗单元高精度，因为内部的自反射数据存储在内存中的个别单位，以正确的操作，即使是高反射率的衰减，可以测量具有优良的精度。
高稳定性的内部高稳定性的传感器可以与半导体激光器一起使用，提供稳定的反射衰减测量。简单的操作安装有一个回波损耗单元和一个半导体激光器单元，显示器将显示反射率衰减后，测量参考反射率，通过仅仅连接测量的光纤电缆。
The Ando AQ2140 Optical Multimeter was developed to serve as universal optical testing instrument. It can be used for a wide range of applications from R&D-- to optical fiber and component manufacture, as well as construction and maintenance. This modular system provides high precision, powerful functions and high-speed measurement, making it one of the most popular instruments for general and integrated applications.
Features
Sensor, sensor unit
●High accuracy
Measurement accuracy of ±2.5% is guaranteed under the reference conditions.
●Wide wavelength range and dynamic range Covers a wide waveband from 400 to 1870nm, and provides a dynamic range of 100dB or more for loss measurement. (It depends on sensors.)
●Low polarization dependence
The AQ2733 and AQ2734 Sensor Units achieve a low polarization dependence of 0.02dBp-p or less.
Main frame
Sensor unit
●High-speed measurement
The minimum measurement interval is 10ms (single sensor unit), improving efficiency by slashing measurement time.
●Precise wavelength correction settings
Sensor wavelength sensitivity can be set in 1nm steps.
●Supports three relative measurement Measurement can be referenced to measured values as in existing systems, or be based on a comparison with data from other channels, or against preset inputs.
●Selectable display resolution
Display resolution can be set to 0.1, 0.01 or 0.001, improving reading efficiency by providing the resolution needed for your specific application. ●Connection to external unit
By connecting extensional frame for Optical Multimeter AQ2141, unit of up to 16 external channels can be used. (Possible connection unit: select one unit from Sensor unit, OPM unit, Light source unit.)
●Data storage function
The main frame can store up to 1000 data points per channel, or 2000 total, and user-selected data can
be output through the GP-IB interface.
●Data display function
Manual operation can be used to check not only individual data in memory, but also maximum, minimum and average values.
