Keysight 86120D opt 21 Wavelength Meter

For the measurement of light sources and signals in the wavelength range from 700 nm to 1700 nm, the new 86120D model offers a compelling set of features with ±1.5 ppm accuracy and a measurement cycle time of 0.6 seconds. Like for the 86122C, all wavelength accuracy specifications apply to single-scan measurements - there is no averaging required. This makes them ideal for fast, automated wavelength adjustment procedures.

The 86120D has been qualified for “General Purpose” environmental operating conditions from 0 °C to +55 °C, including shock and vibration levels for use cases that require robust test equipment.

Keysight multi-wavelength meters are Michelson interferometer- based instruments that measure wavelength and optical power of laser light over a specified wavelength range. Simultaneous measurements of multiple laser lines are performed, allowing measurements of DWDM signals and multiple lines of Fabry-Perot lasers. Each laser line is assumed to have a linewidth (including modulation sidebands) of less than:

– 10 GHz for the 86120D, and – 2.5 GHz for the 86122C

A broadband mode is also available for measuring the weighted center of wider lines.  This technical specifications sheet describes the measurement accuracy and operating conditions of the Keysight 86120D and 86122C Multi-Wavelength Meters. The specifications apply to all functions within the specified environmental conditions. All specifications apply after the instrument’s temperature has been stabilized after 15 minutes continuous operation.
