USB vs Ethernet for Test Equipment?

• Ethernet comes with free isolation


• No drivers required to get Ethernet working


• USB is faster to get working depending on your network hacking skills


• USB software stacks in test equipment are kinda hit or miss

How to make hardware work with Ethernet?

• Still learning about this


• Trying out Arduino -> Ethernet shields that use the Wiznet W5100


• Managed to get a demo working with SCPI and the shield

Tag Connect : Edge-Connect

• https://www.tag-connect.com/product-category/products/edge-connect


• Spring loaded leaf springs in a connector that slides onto the side of a PCB


• Looks like a great alternative to normal tag connect

Bias test connector - OTC (one time connect)

• PEM smtsss-4mm-6et solderable spring standoffs


• Use in conjunction with through hole pogo pins


• Just add holes and target points on main pcb and plug the connector in for access to the nets
