HP / Agilent 54112D 4 CHANNEL DEEP MEMORY DIGITIZING SCOPE

The HP/Agilent 54112D is a four-channel digitizing oscilloscope delivering simultaneous capture at 400 MSa/s per channel across 100 MHz real-time bandwidth. Deep memory architecture records up to 64K points per channel, enabling precise acquisition of complex high-speed transients in research, design validation, and physics applications. The instrument combines flexible triggering logic with waveform analysis tools - zoom, pan, and mathematical functions - to extract actionable data from captured signals.
