I have some probes that measure some biomedical signals.
all of them are connected to a data acquisition board.
all the cables and connectors are terminated with a resistor of 50 Ohm.
each probe has a ground and the acquisition board has a different ground.
How should I connect them to each other?
I think I have two ways as follow
- ground all the coax cables at the side of acquisition board.
- ground all the coax cables at the both side.
