Optical Multiport Power Meter

Keysight's popular N7744A optical power meters with four power-sensor channels provide increased throughput and operational efficiency to meet today's challenges in manufacturing. Designed for characterizing optical multi-port components, these optical power meters offer industry-leading solutions for device connectivity, high-speed measurement data acquisition and fast data transfer for post-processing. The multi-port power meter enables fast measurement solutions for all multi-port devices; for example multiplexers, PON splitters, wavelength selective switches (WSS) and ROADMs, as well as compact setups for simultaneous testing of multiple single-port devices.The N7744A power meter achieve a level of space-saving channel density that is new in the industry. This is complemented by the ease of integrating multiple instruments into a single setup with parallel programming over the LAN or USB connections.Features：1 µs minimum averaging timeFour InGaAs sensor ports with 1250 to 1650 nm wavelength rangeDynamic range up to 65dB in swept and logging applications without rangingPower uncertainty of ±2.5 %Low polarization dependence of <±0.01 dB
