I have an Kasli FPGA Carrier, and an 8-channel SMA TTL card.
I am trying to provide TTL trigger signals to a camera. I can see the correct TTL output on an oscilloscope, however still can't trigger the camera successfully yet.
The camera's requirements for trigger signal is as follows:
Electrical Feature Min Typ Max
Logic Low voltage 0.0V 0.0V 1.0V
Logic High voltage 3.6V 5.0V 5.0V
Required Input Strength – 7mA 15mA
I just wanted to confirm if the drive strength of my SMA TTL card is sufficient to be able to trigger this camera? The camera typically requires a minimum drive strength of 7mA.
I would deeply appreciate it if you could provide me this information as soon as possible. I am trying to find out what could be the possible reason I am unable to successfully trigger my camera.
Thanks a lot for your help,
