The HP/Agilent 83487A is a dual-channel plug-in module for the 83480A, 54750A, and 86100A/B/C mainframes, delivering integrated optical and electrical characterization of high-speed communication waveforms. The optical channel operates across the 750–860 nm band with 2.85 GHz bandwidth and supports 62.5/125 µm multimode fiber, while the electrical channel provides user-selectable 12.4 GHz or 20 GHz bandwidth via 3.5 mm input connector. This two-slot module excels in research, development, and production testing—particularly for Fibre Channel and Gigabit Ethernet transmitter compliance verification.
