11-1-4 FRAME RATE CALCULATION
(1) CoaXPress
Exp1 = 7.309 µs to 10 s (input in units of seconds)
1H = 7.309 µs
Exp2 = ROUNDUP (Exp1 / 1H) * Round up to integer
Vn1 = Number of vertical lines
Vn2 = (Vn1 / 2) + 5
Conditions
Exp2 < 13 682
Exp2 ≥ 13 682
Vn4 = MAX (Vn2 + 2, Exp2)
Operation modes
Free running mode
External trigger mode
(Edge trigger / Level trigger /
Global reset edge trigger /
Global reset level trigger)
External trigger mode
(Synchronous readout trigger)
•
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 10-1-6-3 "Start trigger mode".
• The calculation formula and the frame rate value do not depend on the bit depth of digital output.

Calculation formula
If (Exp2 < 13 682):
1 / (Vn2 + Vn3) / 1H
Others: 1 / Exp2 / 1H
1 / (Vn2 + Exp2 +3) / 1H
1 / (Vn4 + 1) / 1H
