The Keysight Agilent 86105A is a dual-channel optical and electrical oscilloscope plug-in module designed for use with the 86100A, 86100B, and 86100C Infiniium DCA and DCA-J mainframes. It features a 20 GHz amplified optical channel optimized for 9/125 µm single-mode fibers and a 20 GHz electrical channel. Both channels support selectable 12.4 GHz and 20 GHz bandwidth modes to balance noise performance with signal fidelity, while integrated switchable filters enable SDH/SONET reference receiver compliance testing.
