The Keysight (formerly Agilent) 81619A is a dual-channel optical head interface module designed for use with the 8163A/B, 8164A/B, and 8166A/B Lightwave mainframes. It enables the connection of two independent 8162x series optical heads, providing flexible, high-performance power measurements in a single-slot form factor without occupying multiple mainframe slots.
