{ EDGE | LOGIc | PULse | COMMunication (TDS 500C & 700C) | VIDeo
}
(Only the TDS 510A, 500C, 600B, & 700C use the LOGIc and PULse argu-
ments. Only the TDS 500C and 700C use the COMMunication argument. Only
digitizing oscilloscopes with option 05 use the VIDeo argument.)

EDGE is a normal trigger. A trigger event occurs when a signal passes through a
specified voltage level in a specified direction and is controlled by the TRIG-
ger:MAIn:EDGE commands.
LOGIc (TDS 510A, 500C, 600B, & 700C only) specifies that a trigger occurs
when specified conditions are met and is controlled by the TRIGger:MAIn:LOG-
Ic commands.
PULse (TDS 510A, 500C, 600B, & 700C only) specifies that a trigger occurs
when a specified pulse is found and is controlled by the TRIGger:MAIn:PULse
commands.
COMMunication (TDS 500C & 700C only) specifies that a trigger occurs when a
specified signal is found and is controlled by the TRIGger:MAIn:COMMunica-
tion commands.
VIDeo (option 05 only) specifies that a trigger occurs when a specified signal is
found and is controlled by the TRIGger:MAIn:VIDeo commands.
TRIGGER:MAIN:TYPE?
might return PULSE indicating that the main trigger type is a pulse trigger.
