Mode 6: External Frame Rate and Internal Exposure Time
This mode differs according to the trigger rate and the exposure time setting. However,
the following rules apply to any condition:
• Any additional external triggers occurring during the exposure time will be ignored.
• All non-ignored external triggers will pulse an electronic shutter to dump any current
exposure data at the start of the trigger pulse and start the exposure time.
• At the end of the exposure time, the collected data will be transferred to the readout
area only if it is not already in the process of reading out. If readout is already in
process, the exposure time will be extended until the readout is finished, as is
illustrated in
Example 6.
