• The frame rate value is valid 3 digits and rounded down to 4th digit.
• The calculation formula and the frame rate value of Start trigger mode (External trigger mode) are
same as Free running mode. About this mode, refer to 11-1-6-3 “Start trigger mode”.
• The calculation formula and the frame rate value do not depend on the bit depth of digital output.
• Ultra quiet mode is used for the Photon number resolving mode.
