(4) Sub-array readout
Readout of the sub-array repeats according to the sequence set internally.
Command
External control pulse :
Scan mode
Exposure time
Sub-array
Designated time
Minimum repeat cycle can be calculated using the formula below.
Minimum repeat cycle = readout time + external control pulse's LO interval
Exposure time can be calculated using the formula below.
Ex) When the external control pulse's LO interval {HI interval} is 40,
Exposure time = external trigger pulse LO interval {HI interval} - 2.2 μs
