COUPLING
Three-position lever switch; selects coupling for sync
trigger signal.
A C :
Trigger is ac coupled. Blocks dc component
of input signal; most commonly used posi-
tion.
VIDEO
FRAME:
Vertical sync pulses of a composite video
signal are selected for triggering.
VIDEO
LINE:
Horizontal sync pulses of a composite video
signal are selected for triggering. The LINE
position is also used for all non-video
waveforms.

SOURCE
Five-position lever switch; selects triggering source
for the sweep, with following positions;
V. MODE: The trigger source is determined by ver-
tical MODE selection.

Channel 1 signal is used as a trig-
ger source.
Channel 2 signal is used as a trig-
ger source.
The algebraic sum of channel 1
and channel 2 signal is the trigger
source. (If CH2 INV engaged, the
difference
becomes the trigger
source.)
