The Tektronix 7834 is a 400 MHz multi-mode CRT storage scope that takes two vertical and two horizontal 7000-series plug-ins.

It was the fastest analog-storage scope in the 7000 series, both in terms of bandwidth and writing speed, from its introduction in 1977 until it was superseded by the 500 MHz 7934 in 1987.
