儀器介紹
The Agilent 81635A is a dual optical sensor plug-in module that fits the 8163, 8164 and 8166 multichannel mainframe series. The Agilent HP 81635A includes two InGaAs sensor elements with a wavelength range of 800 to 1650nm and a dynamic range of +10 to -80dBm. Many different connectors are available for the 81635A power meter interface.
Keysight's 81635A dual optical power sensor is the right choice for accurate power measurements on fiberoptic devices. The modular dual sensor fits 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.
