system is running but the trigger system is not
receiving valid trigger events. This includes when
auto triggering in absence of a trigger.
H TRIG’D lights when the instrument acquisition
system is running and the trigger system is
triggered.
H READY and TRIG’D are always off if acquisition is
stopped.
