External, rising / External, falling
If this mode is active, as with the edge trigger, a rising or fall-
ing edge is awaited. However, the decisive factor in this case is
not one of the analog signals, but the digital signal at I / O port
D23 (pin 26). As with the analog edge trigger, only a logical
edge triggers the trigger. A static signal is ignored. The exter-
nal trigger is for synchronization with other devices. Please
check the compatibility of the trigger source and the MEphisto
Scope. Modern signal generators usually generate a 5 V CMOS
signal, which you can use as a synchronous pulse.
