The keysight (Agilent) Technologies 8163A Lightwave Multimeter is a modular optical mainframe engineered for optical component testing with broad flexibility. It supports plug-in modules from both the 816xxx and 815xxx series, enabling diverse test configurations. The mainframe features a monochrome graphical display (190 x 300 points) with high-resolution output (0.0001 dB/dBm and 0.01 pW to 10 pW). It offers true synchronous triggering across all channels for precise, coordinated measurements. The 8163A also integrates built-in applications and provides connectivity via GPIB, parallel, and serial ports, streamlining automation in lab environments.
Perfect for telecom and R&D applications, the 8163A is adaptable, accurate, and efficient for fiber optic testing setups.
