4.5.2.1 Trigger System
A dynamic measurement sequence is specified by the selected sample
interval (0.01 ... 1000.00 ms) and the required number of sample points
(Sample Length: 1... 5000). It is initialized by starting the sample mode
(Sample Start > „on“ ) and then the trigger system detects the valid
sample values depending on the selected trigger parameters. The
measurement stops if either the selected number of values has been
taken or the measurement buffer is full.
The trigger system allows the start of recording a signal before, at or
after the trigger signal. Therefore a trigger offset can be set between -
5000 to 50000. With a positive trigger offset a trigger delay can be ge-
nerated depending on the selected sample intervall.

The trigger system of the NGMO2 allows the automatic repetition of
such measurement sequences up to 99 times to build average pulse
values. Therefore a triggercount is settable between 1 and 100 in the
menue which represents the number of sequences to be executed be-
fore the measurement is stopped.
