The Tektronix 7A42 is a four-channel 350 MHz plug-in for 7000-series scopes.
It was specifically designed for logic signals (TTL, ECL, CMOS) and supports triggering based on Boolean conditions of the four inputs.
A fifth trace, "Trigger View", displays the trigger function output or external clock input.
