niconiconi<p>Just reverse-engineered this generic SMA Thru connector using a set of 1-micron gauge pins (in 0.05 mm increments). It turns out that one side of adapter appears to be deliberately designed to violate the spec, possibly to prevent simultaneous rotation. :blobcatfacepalm: Never use these adapters with high-end instruments or cables. <a href="https://mk.absturztau.be/tags/electronics" rel="nofollow noopener noreferrer" target="_blank">#electronics</a></p>
