Thanks to help from one of the contributors of the scikit-rf project, there is an even more accurate method than the de-embedding step that was earlier described. I&#39;ve updated the blog post to also include that method.</p> <p>Now the corrected measurement almost looks like a dot:</p> <p><img alt=" " height="542" src="/resized-image/__size/1038x1084/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-93374d9e-8a92-4f22-907a-30cf575ed500/ecomp_2D00_screenshot.jpg" width="518" /></p> <p>In summary, the DIY calibration standards can work very well, at least to a GHz, if not more.</p> <p></p><img src="https://community.element14.com/aggbug?PostID=27485&AppID=13&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/technologies/test-and-measurement/b/blog/posts/vector-network-analyzer-vna-a-practical-getting-started-guide-for-the-general-readerTue, 23 Jan 2024 19:59:30 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:93374d9e-8a92-4f22-907a-30cf575ed500DAB1<p>Very good overview of VNA and the use of Smith Charts.</p><img src="https://community.element14.com/aggbug?PostID=27485&AppID=13&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/technologies/test-and-measurement/b/blog/posts/vector-network-analyzer-vna-a-practical-getting-started-guide-for-the-general-readerTue, 23 Jan 2024 18:54:34 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:93374d9e-8a92-4f22-907a-30cf575ed500rsjawale241<p>I will read the entire blog in my free time, but I just checked the FPC1500 review. It looks to be an Spectrum analyser with a tracking generator. Which makes it a scalar network analyser and not a VNA. A vector network analyser with give phase information along with the S parameter magnitude</p><img src="https://community.element14.com/aggbug?PostID=27485&AppID=13&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/technologies/test-and-measurement/b/blog/posts/vector-network-analyzer-vna-a-practical-getting-started-guide-for-the-general-readerTue, 23 Jan 2024 17:32:40 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:93374d9e-8a92-4f22-907a-30cf575ed500javagoza2<p>I don&#39;t know where you find the time for so much production.&nbsp;Now I have the need to buy a VNA to learn by experimenting.
