* ''Alt Drive'' − 0/+5 V; high level will display channel 2 of a dual-trace plug-in, low will display channel 1. | * ''Alt Drive'' − 0/+5 V; high level will display channel 2 of a dual-trace plug-in, low will display channel 1. | ||
* ''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]]. | ||

* ''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. | * ''Sweep Inhibit/Sweep Lockout'' - Mainframe injects current > 1 mA to prevent time base from sweeping.
