* ''Intensity Limit'' − Switched to ground by timebase in slow sweep speeds (≥100 ms/Div), limits beam intensity to protect the CRT [[phosphor]] | * ''Intensity Limit'' − Switched to ground by timebase in slow sweep speeds (≥100 ms/Div), limits beam intensity to protect the CRT [[phosphor]] | ||
* ''Mainframe Channel Switch'', ''Mainframe Mode'' − 0/+5 V logic levels; plug-in output is displayed when MF Channel Switch ≠ MF Mode (XOR) | * ''Mainframe Channel Switch'', ''Mainframe Mode'' − 0/+5 V logic levels; plug-in output is displayed when MF Channel Switch ≠ MF Mode (XOR) | ||
* ''Sweep Inhibit/Sweep Lockout'' - Mainframe injects current > 1 mA to prevent time base from sweeping. Used for ALT sequencing. | * ''Sweep Inhibit/Sweep Lockout'' - Mainframe injects current > 1 mA to prevent time base from sweeping. Used for ALT sequencing and delayed sweep of the ''B'' time base. | ||
* ''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. +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. Mainframes connect this signal from the ''A'' timebase through a 2k 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. | ||

* ''X comp. inhibit'' − Connected to ground in amplifiers, switched to ground by timebase set to amplifier (X-Y) mode to enable X-Y delay compensation in scopes with that function ([[7904|7904 Opt.2]], [[7104|7104 Opt.2]]) | * ''X comp. inhibit'' − Connected to ground in amplifiers, switched to ground by timebase set to amplifier (X-Y) mode to enable X-Y delay compensation in scopes with that function ([[7904|7904 Opt.2]], [[7104|7104 Opt.2]]) | ||
