Single Either
: The trigger source output is HIGH when a rising or a falling edge is detected on
the selected input pin. Once the trigger source is in a logically high
state, it stays high until
reset.
•
Positive Level
,
Negative Level
: The level or the inverted level of the selected input pin is for-
warded to the trigger source output.
I
n this case the state of the trigger source depends on
the level of the input pin.
The next
fi
eld
Channel
allows for selecting the desired input pin. The pin labels are in accordance
with the pin labels of the
PICO
SCALE
Breakout-Box (BOB).
Trigger Event

•
Positive Level
,
Negative Level
: The level or the inverted level of the input pin is forwarded to
the trigger source output, respectively.
I
n this case the state of the trigger source depends
on the level of the input pin.
All other

Trigger Event
Internal Event
The last
Event
,
Internal Event
, reacts to signals that are generated when internal events occur, for
example a

selected event signal. The following conditions are available:
•
Single Rising

The next two
