Alright, bit of a silly question but I can't seem to get Digikey or Mouser to show me what I want.
I'm wanting to replicate Fig. 7 of this INA116 datasheet almost exactly. Before I go and buy this expensive IC, I'm mapping out how I'll build the coax setup at the top of Fig. 5; I'm having difficulty figuring out what cable and connector I'll use, though.
What I'm imagining is a single conductor coaxial cable that features a BNC or SMA at one end and a minigrabber / alligator clip / kelvin clip / similar at the other end (I use a mix of custom and standard electrodes with both planar and pin contact geometries); the BNC or SMA allows me to tie the coax shield to my guard loops on the PCB. However, the search terms I'm using for Digikey and Mouser turn up either unterminated coax spools or BNC test cables where the connector shield is just a separate wire (therefore, not coax at all).
Does someone know what the correct search term is for what I'm looking for? Or is this something uncommon enough that I'll have to make custom cables?
