Has anyone used a NanoVNA to characterize a Twin wire twisted Balanced line like say a CAN bus line or an ISO-SPI balanced 120 ohm line? If so what interface hardware has been used or is recomended?

Howdy, Are there any US Manufacturers building/selling NanoVNAs? I am on a project that is regulated by The Build America Buy America Act and NDAA889 Laws which unfortunately make the linked purchase
