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 2.9. 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
