Notes:
DN = Digital Numbers (0-255); also known as gray levels.
ECE = Exposure Control Enabled
ECD = Exposure Control Disabled
• All measurements taken in 8-bit output mode.
• All measurements are valid for front plate temperatures in still air.
• All measurements used a Tungsten halogen light source, 3200K bulb temp., and
750nm cutoff filter
1. All specifications for the 30MHz model are preliminary.
2 Due to FPN/PRNU correction calculations, certain digital numbers will be
unavailable when outputting 10 bits with FPN/PRNU correction.
3 Measured at front plate. The corresponding ambient temperature range with still air
is 0°C - 37°C.
4 Measurements taken at maximum line rates.
