Pascalne<p>My budget electronics lab I’ve been putting together for the past year. The oscilloscope is a Hantek DSO2D10 which I’ve found to be good value with SCPI support.👍The big multimeter is a DATRON 1061 a metrology grade 5.5 digit multimeter. The multimeter on top is a 6.5 digit Solartron 7151 which I developed some <a href="https://mastodon.social/tags/opensource" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>opensource</span></a> software for. Thinking of replacing them both with something like a HP34401A.
