The Keysight (Agilent) 81533A and 81533B are optical head interface modules designed to operate exclusively with the 815xx series optical heads and are compatible with mainframes such as the 8153, 8163, and 8164. These modules act as the critical link between the optical heads and the mainframe, enabling precision photonic measurements. While Agilent does not publish standalone specifications for the 81533A/B, performance is defined by the head and mainframe used. Specifically, the 81533A module is compatible with optical heads 81521B and 81524A, supporting accurate power measurements in fiber optic test environments.
These interface modules are ideal for lab and field applications where modularity and flexible measurement configurations are essential in optical power testing.
