The Keysight 81630B provides measurement of high power levels in the convenient front-panel input format of the sensor modules. For measuring lasers and transmitters beyond 10mW, this is the sensor to choose.
Keysight optical power sensors are the right choice for accurate power measurements on fiber optic devices. The modular sensors fit into all Keysight 816x Lightwave mainframes and can be used singly or in multiples for parallel measurements of multichannel devices. The output fiber is easily attached using Keysight's flexible connector adapters or bare-fiber adapter.
The module can run measurement applications like data logging, stability and recording minimum and maximum values over time. Triggered synchronization with tunable laser modules enables powerful spectral measurements, with the advantages of higher resolution, better polarization dependence and cost-and-time-efficient multichannel expandability. The module logs up to 20,000 samples with averaging time as low as 100µs.
