Agilent / HP / Keysight 81636B

This Power sensor is the right choice for accurate power measurements on fiberoptic devices. The modular sensor fits into all Agilent 816x Lightwave mainframes and can be used singly or in multiples for parallel measurements of multichannel devices. The output fiber is easily attached using Agilent'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 100,000 samples with averaging time as low as 25µs. The analog bandwidth of 17kHz supports fast logging without distortion and the analog output is available for real time oscilloscope measurements.
