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.
