2.10 PULSE GENERATOR
The camera has a built in pulse generator. The user can program the camera to generate a
discrete sequence of pulse or a continuous trail – Figure 2.25. The pulse generator can be
used as a trigger signal, or can be mapped to one of the outputs – refer to “I/O Control”
section for more information. The discrete number of pulse can be set from 1 to 65530 with
a step of 1. The user has options to set:
-
Granularity
– Indicates the number of clock cycles that are used for each increment of
the width and the period. Four possible options are available (x1, x10, x100 and x 1000).
-
Period –
Indicates the amount of time (also determined by the granularity) between
consecutive pulses. Minimum value is 1, maximum is 1048576
-
Width –
Specifies the amount of time (determined by the granularity) that the pulse
remains at a high level before falling to a low level. Minimum value is 1, maximum is
524288
