The Yokogawa / Ando AQ2200 Series Multi Application Test System is the ideal system for measuring and evaluating a wide range of optical devices and optical transmission systems. A variety of measurement modules are available, including the following: a high-stability light source, a wideband tunable laser source, a high-speed optical sensor with low PDL, a high-resolution variable optical attenuator, a small-sized bit error module with an integrated pulse pattern generator (PPG) and error detector (ED), an optical modulator with variable extinction ratio, and an optical receiver supporting two wavelengths (1310 and 1550 nm) and XFP interface module. These modules can be installed in any combination on a single platform, providing an ideal measurement system for a variety of applications. The AQ2200 Multi Application Test System is available in two different frame controller platforms. Each model has a certain number of slots for connecting modules, so you can select the best platform size for your intended measurement applications.
