Output trigger specifications
The SourceMeter can be programmed to output a trigger after various trigger model
actions. (See
“Trigger models,” page 11-30 .) The output trigger provides a TTL-
compatible output pulse that can be used to trigger other instruments. The specifications
for this trigger pulse are shown in
Figure 11-7 . A trigger link line can source 1mA and sink
up to 50mA.
