Agilent/Keysight 8167B,Lightwave Test System

The Agilent/Keysight 8167B is a tunable optical source engineered for precision characterization of optical components and systems across research, development, and manufacturing environments. Delivering stable, accurate optical signals from 1200 nm to 1650 nm with 1 pm wavelength resolution and ±20 pm accuracy, the 8167B provides continuous-wave output up to +20 dBm with exceptional power stability of ±0.01 dB over 1 hour. The benchtop instrument features a 7-inch color LCD display, front-panel controls, and full programmability via GPIB, LAN, USB, and RS-232 interfaces.

Remote operation and SCPI command support enable integration into automated test systems. Operating from 0 °C to +45 °C in environments up to 2000 m altitude, the 8167B maintains performance under demanding laboratory and production conditions. Compact at 430 × 220 × 485 mm and weighing 10.0 kg, it integrates with Keysight optical instruments including the 8163B, 8164B, and 8166B mainframe systems.
