simulate this circuit – Schematic created using CircuitLab
Hi everyone, I recently completed the construction of a spectrometer that studies electron transfer events in inorganic molecules. I am trying to further improve my design however, mainly one major flaw.
I'd like to control where the output of my photomultiplier (PMT) tube is going using a set of BJT transistors as we currently have to manually plug the BNC into the appropriate device. Given the complexity of the setup, it's not feasible to expect workers in the future to be able to do this.
I am somewhat unsure as to how BNC/coax cables operate and would like to ensure that my circuit will work before I invest the effort into building the switch box.
The TTL logic to each gate is to come from an NI USB 6008 IO box.
