The Keysight (Agilent) 8166A is a Lightwave Multichannel System mainframe designed for complex, high-port-count optical component and system testing. Accommodating up to 17 single-slot optical modules, this 4U rackmount system provides a highly flexible platform for multiport power measurement, optical attenuation, and multichannel laser source configurations, controlled via GPIB or RS-232.
