* ''Delay Mode Control'' − Output on delaying timebase in horizontal slot A, connected to input on delayed timebase in horizontal slot B. >+3 V disables auto sweep in delayed timebase; 0 V enables independent timebase function. Grounded in amplifier plugins. | * ''Delay Mode Control'' − Output on delaying timebase in horizontal slot A, connected to input on delayed timebase in horizontal slot B. >+3 V disables auto sweep in delayed timebase; 0 V enables independent timebase function.

* ''Trigger Holdoff'' − 0/+5 V, generated by time-base, high during holdoff time of time-base, used in mainframe for ALT sequencing. | * ''Trigger Holdoff'' − 0/+5 V, generated by time-base, high during holdoff time of time-base, used in mainframe for ALT sequencing. | ||
* ''Chop Drive'' − 0/+5 V; switches at one-half the rate of the VERTICAL MODE CHOP signal; high level selects channel 2, low level selects channel 1 of a dual-trace plug-in. | * ''Chop Drive'' − 0/+5 V; switches at one-half the rate of the VERTICAL MODE CHOP signal; high level selects channel 2, low level selects channel 1 of a dual-trace plug-in. | ||
