I then moved to the spectrum analyzer and did some tests at (much) higher frequencies. Only included 10 and 30MHz here, but pattern is clear: harmonics are generally nicely attenuated, more than 60dB, although at the high end, it’s not quite that much, more like 50dB and a sub-carrier spur appeared as well. Makes me wonder how well the 60MHz version performs 🤔<a href="https://techhub.social/tags/testandmeasurement" class="mention hashtag" rel="nofollow noopener" target="_blank">#testandmeasurement</a> <a href="https://techhub.social/tags/rfengineering" class="mention hashtag" rel="nofollow noopener" target="_blank">#rfengineering</a> <a href="https://techhub.social/tags/rfengineer" class="mention hashtag" rel="nofollow noopener" target="_blank">#rfengineer</a> <a href="https://techhub.social/tags/electronics" class="mention hashtag" rel="nofollow noopener" target="_blank">#electronics</a> <a href="https://techhub.social/tags/electronicsengineering" class="mention hashtag" rel="nofollow noopener" target="_blank">#electronicsengineering</a> <a href="https://techhub.social/tags/uni" class="mention hashtag" rel="nofollow noopener" target="_blank">#uni</a>-t <a href="https://techhub.social/tags/hamradio" class="mention hashtag" rel="nofollow noopener" target="_blank">#hamradio</a> <a href="https://techhub.social/tags/hamr" class="mention hashtag" rel="nofollow noopener" target="_blank">#hamr</a>

Kevin P. FlemingLooking for anyone who has experience with cheap 1- or 2-channel digital oscilloscopes like FNIRSI or similar brands. I occasionally need to check hardware at home to see if I've configured it properly, or if the components are working properly, and not really keen on spending a lot of money.My immediate need is for checking the time pulse output from a GPS receiver, so 3.3V/1Hz is fine.<a href="https://mastodon.km6g.us/tags/Oscilloscopes" class="mention hashtag" rel="nofollow noopener" target="_blank">#Oscilloscopes</a> <a href="https://mastodon.km6g.us/tags/Electronics" class="mention hashtag" rel="nofollow noopener" target="_blank">#Electronics</a> <a href="https://mastodon.km6g.us/tags/Makers" class="mention hashtag" rel="nofollow noopener" target="_blank">#Makers</a>

Some offered features that are hard to reproduce with any modern scope. The 7A22 was a high-gain (up to 10 μV/div) 1 MHz differential amplifier with adjustable high and low-pass filters. The 7A13 was a 100 MHz differential amplifier with an adjustable dc source that could be applied to either input. Both were introduce in 1969. <a href="https://mas.to/tags/electronics" class="mention hashtag" rel="nofollow noopener" target="_blank">#electronics</a>
