* ''Delay Gate'' − negative-going pulse starting at the end of the delay period, and lasting until the end of the sweep from the delaying timebase. Mainframes connect this signal from the ''A'' timebase through a 2 k resistor and a diode to B8 ''Sweep inhibit'' of the ''B'' time base to trigger the delayed sweep. +Gate Output on mainframe uses Delay Gate from H slot B when Delay Gate is selected. Grounded in amplifier plugins. | * ''Delay Gate'' − negative-going pulse starting at the end of the delay period, and lasting until the end of the sweep from the delaying timebase.
