The Tektronix 7834 is a 400 MHz analog storage oscilloscope built around a multi-mode CRT storage architecture for capturing and analyzing high-speed transient waveforms. It accepts two vertical and two horizontal 7000-series plug-in modules, enabling customized measurement configurations across diverse applications. The instrument delivers exceptional writing speed through fast variable persistence mode—reaching 5500 Divisions/µs in reduced scan—making it ideally suited for single-shot event capture. Four distinct storage modes (bistable, variable persistence, fast bistable, and fast variable persistence) combined with normal and reduced-scan options provide the flexibility needed for both real-time and stored waveform analysis.
