I am not an expert in this area and therefore need suggestion regarding what is the best way out for this case.
For my experiment, I am installing a camera that requires a BNC based trigger signal. In the manual, it suggests the properties as given in the picture:
From what I have known so far, there are usually 50 or 75 ohms BNC connectors and cables. Where can I find 1 kOhms available?
Second, what exactly LVTTL means? Previously, I was using 1.7 V rising edge required trigger signal.
Any help would be appreciated. Thanks!
