The Tektronix 1103 is a dual-channel TEKPROBE power supply designed to provide external power and offset control to active probes and optical-to-electrical converters when the host oscilloscope or digitizer does not have built-in TEKPROBE interface capabilities. It features two independent channels, each equipped with fine and coarse offset controls, enabling seamless integration of advanced active probes into any standard BNC measurement setup.
