• T
xfr
(Transfer Time)
This interval represents the time it takes to transfer data from the photosites to
the vertical shift register.
This time is sensor dependent.
Refer to
Table 6-4 for typical values.
• T
read
(Readout Time)
This interval represents the time it takes to read the image from the sensor.
This time is sensor dependent.
Refer to
Table 6-5 for Readout Times that have been measured.
• T
r
(Recovery Time)
This interval represents the time from the end of sensor readout to the time the
system can accept another trigger pulse.
The recovery time is approximately 1

s.
• Maximum Trigger Rate
The Maximum Trigger Rate is related to the minimum time between triggers
which may be calculated as:
T
