The Tektronix 7844 is a 400 MHz dual-beam CRT oscilloscope that takes two 7000-series vertical plug-ins and two 7000-series horizontal plug-ins.

Versions include the 7844 bench-top lab scope and R7844 rack-mount model.

A typical configuration might have included 7A24 or 7A19 amplifiers, a 7B80 and a 7B85 timebase.

Specifications

Internals

The 7844's CRT has distributed vertical deflection plates.

The power supply is a resonant switch-mode inverter with linear post-regulation, similar to the one in the 7904, unlike which the 7844 does have a fan.
