Required Time
t1
Effective Trigger Input Pulse
>10μsec.
t2
Time required from the starting of the
External Trigger to the starting of the Internal
Trigger Signals
(may delay caused by the photocoupler)
<1μsec.
t3
Time required from the starting of the
Internal Trigger Input to the Exposure Time
<1μsec.
t4
Strobe Time
t5
＋
t6
t5
Exposure Time
Exposure Time =
the setting value of the Shutter Speed * 1 H period
※
1 H period = 560(Minimum) * 1PCLK
＝
11.2μsec.
※
1PCLK = 1/50,000,000sec. = 0.020μsec.
t6
Time required for data transfer
(from the sensor to the FPGA)
（
Effective Vertical Pixels
＋
2
）
* 1 H period
t7
Time required for the transfer (from the
FPGA to USB)
>3 H period
t8
Time required from the completion of the
sensor data transfer to the completion of the
USB data transfer
>3 H period
t9
Time required from the completion of the
internal data transfer until the next trigger
input becomes available
Approx. 1 H period
