The Tektronix Type 184 is a compact crystal-controlled time-mark generator, introduced in 1965 and discontinued after 1971. It was replaced by the 2901.
The generator produces push-button selectable time marker intervals from 2 nanoseconds to 5 seconds. Multiple markers can be stacked by pressing buttons simultaneously.
The task of designing the 184 was inherited and completed by Murlan Kaufman.

Internals
The 184 contains a 10 MHz crystal in a 75°C oven. The circuit is solid-state except for six 7587 Nuvistor vacuum tubes used in the 10 MHz oscillator, and the 20/50/100/500 MHz multiplier circuits. The 200 MHz stage is a passive multiplier using diodes.
