The maximum USB bandwidth is :
[USB Limit] = 5120 x 3840 x 8bit x 16.00 fps = 2516582400 bps
(1) IF V-Binning is Off,
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],
a) IF [USB Limit] < [USB Rate],
[Output Rate] = [USB Limit] ÷ [Width] ÷ [Height] ÷ 8
b) IF [USB Limit] > [USB Rate],
[Output Rate Rate] = 1/((([Height] x 641) + 38580) ÷ 40 MHz)
[Trigger Period] = (2/ ([Output Rate])+[Exposure Time:10 us ~8s])
+ 130 us + 16.025 us
(2) IF V-Binning is On,
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],
a) IF [USB Limit] < [USB Rate] ,
[Output Rate] = [USB Limit] ÷ [Width] ÷ ([Height] x 2) ÷ 8
b) IF [USB Limit] > [USB Rate],
[Output Rate] = 1/((([Height] x 1282) + 38580) ÷ 40 MHz)
[Trigger Period] = (2/ ([Output Rate])+[Exposure Time:10 us ~8s])
+ 130 us + 32.050 us
- (1) IF V-Binning is Off,
= (2/ ([Output Rate]) - (2 x ((([Height] x 641) + 38580) ÷ 40 MHz)
(2) IF V-Binning is On
= (2/ ([Output Rate]) - (2 x ((([Height] x 1282) + 38580) ÷ 40 MHz)
