If your test tools have a USB or LAN port, there is a good chance that they support SCPI. Using pyVISA, you can write automated test programs for most equipment without expensive software. This video explains terms like VISA, SCPI, and USBTMC. Then it shows how to use Python and pyVISA to connect to test equipment with a Raspberry Pi (or any Linux computer.)
