(2) 2×2 binning readout
Exposure and 22 binning readout repeat according to the sequence set internally.
Command
External control pulse :
Scan mode
Exposure time
Binning
Designated time
Minimum repeat cycle can be calculated using the formula below.
Minimum repeat cycle = 46.9 ms (readout time) + external control pulse's
Exposure time can be calculated using the formula below.
Exposure time = external trigger pulse LO interval {HI interval} - 2.2 μs
Ex) When the external control pulse's LO interval {HI interval} is 40,
Exposure time = 40 μs - 2.2 μs (MAX) + 152 μs (MAX) = 189.8 μs (MAX)
