81636B Fast Optical Power Sensor

OVERVIEW 25 µs minimum averaging time and 17 kHz analog bandwidth Dynamic range in manual range mode: > 55dB Power uncertainty: ±3% Low polarization dependence: <±0.015dB 100,000 measurement samples The Keysight 81636B Universal Optical Power Sensor is ideal for making accurate power measurements on fiber optic devices. This modular sensor is suitable for use with a variety of Keysight 816x Lightwave mainframes and can be used alone or in groups to measure multi-channel devices in parallel. The output fiber can be easily connected using Keysight's flexible connector adapters or bare fiber adapters. This module can run a variety of measurement applications, such as data logging, stability testing, recording minimum and maximum values ​​over time. The trigger synchronization capability with the tunable laser source module allows you to perform powerful spectral measurements - with higher resolution and better polarization correlation, enabling cost-effective and time-saving multi-channel expansion. This module can record up to 100,000 samples with an average time as short as 25 µs. The analog bandwidth of 17 kHz supports fast recording without distortion, and the analog output can be used to perform real-time oscilloscope measurements. Advantages: Short averaging times and wide bandwidth make it possible to acquire up to 100,000 samples, providing high-resolution spectra without distortion at high scan speeds even on narrow filters. NIST and PTB traceability allows you to measure uncertainty to internationally recognized standards. The instrument features a comprehensive sampling and triggering concept (hardware trigger line, filtering, event trigger, hardware timer, analog output) that enables the power meter to flexibly meet changing test requirements and to be easily integrated into a wide variety of applications.
