The Agilent/Keysight 86122A is a precision multi-wavelength meter for high-accuracy optical wavelength and power measurements across the C and L bands. Engineered for R&D and manufacturing environments, it characterizes DWDM transmission systems and optical components with absolute accuracy to ±0.2 ppm and simultaneous measurement of up to 1000 laser lines. The instrument delivers wavelength scan times under 0.5 seconds with a minimum resolvable channel spacing below 5 GHz, supported by an internal HeNe laser standard.
