The Fluke PM3382A Autoranging CombiScope is a dual-channel oscilloscope that unifies analog and digital measurement capabilities in a single instrument. Operating at 100 MHz bandwidth, it delivers automatic setup and triggering to streamline signal analysis across complex waveforms, video signals, single events, and low-repetition-frequency measurements. The instrument switches between analog and digital modes to optimize performance for each acquisition type.
