How to send trigger pulse to external device with BNC connectors?

[OtoGuy]

Hello,

I recently purchased a USB-6008 unit. My goal is to send a 5V trigger pulse simulataneously to 2 nerve stimuators which accept only BNC inputs. If possible, I would like to send 500 microseconds pulses at regular intervals (~1/sec). Hopefully I can coordinate this with force gauge inputs via USB or rs232.

Any advice on how to connect the usb6008 outputs to BNC inputs would be much appreciated. Also, is it possible to accomplish the above set-up with the usb6008?

Thanks for your help!

If you are just concerned about making the connection, probably the easiest way is to take a standard BNC-to-BNC cable and chop it in half.  Then take one of the sections and strip/tin the center and shield conductors and connect to one of the digital out and ground screw terminals on the USB-6008.  You can use a standard BNC "T" connector to connect this trigger line to both stimulators to trigger them simultaneously.
