Minimum Trigger Interval Calculation Formula
[Unit：us]
The maximum USB bandwidth is :
[USB Limit] = 5120 x 3840 x 8bit x 16.00 fps = 2516582400 bps
The Data Rate by ROI setting is:
[USB Rate] = [Width] x [Height] x 8 ÷ ((([Height] x 641) + 38580) ÷ 40 MHz)
As comparing [USB Limit] and [USB Rate]
(1) IF [USB Limit] < [USB Rate],
[Readout Rate] = [USB Limit] ÷ [Width] ÷ [Height] ÷ 8
(2) IF [USB Limit] > [USB Rate],
[Readout Rate] = 1/((([Height] x 641) + 38580) ÷ 40 MHz)
[Trigger Period] = (1/ ([Readout Rate] + [Trigger Pulse Width: 10 us~] ))
+ 16.025 us
The Data Rate by ROI setting is:
[USB Rate] = [Width] x [Height] x 8 ÷ ((([Height] x 1282) + 38580) ÷ 40 MHz)
As comparing [USB Limit] and [USB Rate],
(1) IF [USB Limit] < [USB Rate],
[Readout Rate] = [USB Limit] ÷ [Width] ÷ ([Height] x 2) ÷ 8
(4) IF [USB Limit] > [USB Rate],
[Readout Rate] = 1/((([Height] x 1282) + 38580) ÷ 40 MHz)
[Trigger Period] = (1/ ([Readout Rate] + [Trigger Pulse Width: 10 us~] ))
+ 32.050 us

As comparing [USB Limit] and [USB Rate],
(1) IF [USB Limit] < [USB Rate],
[Readout Rate] = [USB Limit] ÷ [Width] ÷ [Height] ÷ 8 ÷ 2
