Triggering
Model 6485 Picoammeter Instruction Manual
Input trigger requirements
An input trigger is used to satisfy event detection for a trigger model layer that is using the
TLINK control source. The input requires a falling-edge, TTL compatible pulse with the
specifications shown in
.

Trigger link input pulse specifications
Output trigger specifications
Model 6485 can be programmed to output a trigger immediately after a measurement and/
or when operation leaves the trigger layer of the trigger model. The output trigger provides
a TTL-compatible output pulse that can be used to trigger other instruments. The specifi-
cations for this trigger pulse are shown in
. A trigger link line can source 1mA
and sink up to 50mA.
