11-2-3 FRAME RATE CALCULATION
(1) CoaXPress
Exp1 = 7.2 µs to 274.9 ms (input in units of seconds)
1H = 7.2 µs to 237.6 µs
Exp2 = ROUNDUP (Exp1 / 1H) * Round up to integer
Vn1 = Number of vertical lines
Vn2 = (Vn1 + 6) / 2 + 2

Note
•
The frame rate value is valid 3 digits and rounded down to 4th digit.
Note
•
The calculation formula and the frame rate value of Start trigger mode (External trigger mode) are
same as Free running mode.
Note
•
The calculation formula and the frame rate value do not depend on the bit depth of digital output.
