For the measurement of light sources and signals in wavelength ranges from 700 nm to 1700 nm, the 86120D Multi-Wavelength Meter offers a compelling set of features. With ±1.5 ppm accuracy (typical ±1 ppm) and a measurement cycle time of just 0.6 seconds, it is ideal to achieve fast, automated wavelength adjustment procedures. Keysight multi-wavelength meters are Michelson interferometer-based instruments that measure wavelength and optical power of laser light over a specified wavelength range. A built-in HeNe laser guarantees an accurate absolute wavelength measurement against a natural standard any time. Simultaneous measurements of multiple laser lines are performed, allowing measurements of DWDM signals and multiple lines of Fabry-Perot lasers. A broadband mode is also available for measuring the weighted center of wider lines. Benefits: Just 15 minutes of warm-up time are sufficient for specified accuracy. Angled-connector option is available to avoid influencing non-isolated sources. The wide wavelength range covers all communication test applications. With +18 dBm safe input level, optical power values up to +10 dBm can be measured without additional equipment (e.g. attenuator). The built-in applications for optical signal-to-noise ratio, wavelength and power drift allow smart stand-alone test solutions with compact footprint, avoiding costly test procedure development.
