We initially ordered the commercially available SSR10VS\/HS-10135 choke.

This is a digital USB multifunction device that, in addition to its two oscilloscope channels, includes two signal generators, a programmable laboratory power supply from 0.5V to 5V, a logic analyzer, and several other features.<\/p>\n<p>Setting up the Discovery 2 turned out to be surprisingly easy once you&#039;ve got the relevant software and documentation. It&#039;s largely self-explanatory, making it &quot;plug and play.&quot; After plugging in the Discovery and installing the associated WaveForms software, the measurement process becomes almost intuitive, saving you the trouble of connecting a real oscilloscope to your PC via a network.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-7263 alignright\" src=\"https:\/\/medtech-ingenieur.de\/wp-content\/uploads\/2022\/09\/bnc_adapter-1-300x233.png\" alt=\"\" width=\"240\" height=\"187\" srcset=\"https:\/\/medtech-ingenieur.de\/wp-content\/uploads\/2022\/09\/bnc_adapter-1-300x233.png 300w, https:\/\/medtech-ingenieur.de\/wp-content\/uploads\/2022\/09\/bnc_adapter-1-768x598.png 768w, https:\/\/medtech-ingenieur.de\/wp-content\/uploads\/2022\/09\/bnc_adapter-1-100x78.png 100w, https:\/\/medtech-ingenieur.de\/wp-content\/uploads\/2022\/09\/bnc_adapter-1-150x117.png 150w, https:\/\/medtech-ingenieur.de\/wp-content\/uploads\/2022\/09\/bnc_adapter-1-200x156.png 200w, https:\/\/medtech-ingenieur.de\/wp-content\/uploads\/2022\/09\/bnc_adapter-1-450x350.png 450w, https:\/\/medtech-ingenieur.de\/wp-content\/uploads\/2022\/09\/bnc_adapter-1-600x467.png 600w, https:\/\/medtech-ingenieur.de\/wp-content\/uploads\/2022\/09\/bnc_adapter-1-900x700.png 900w, https:\/\/medtech-ingenieur.de\/wp-content\/uploads\/2022\/09\/bnc_adapter-1.png 1000w\" sizes=\"auto, (max-width: 240px) 100vw, 240px\" \/><\/p>\n<p>In order to be able to use oscilloscope probes or BNC cables in general on the Discovery 2, we used an associated expansion board on which the two oscilloscope channels and the two signal generators are implemented as a single BNC socket.<\/p>\n<p>&nbsp;<\/p>\n<h3><strong>Measurement results of the DIY transformer<\/strong><\/h3>\n<p>When measuring the commercial choke, we were able to confirm the frequency response from the datasheet, but at the same time, we discovered that below the frequency shown in the datasheet, it didn&#039;t have the linear relationship we were looking for. Researching various electronics blogs, we came up with the idea of winding the required 1:1 transformer ourselves from twisted-pair cables. Since we still had old network cables and coil cores lying around from other projects, the next logical step was to replicate the approach we had found. After a bit of winding work and a toroidal transformer with a total of 40 windings, we measured this new homemade component again with the Discovery 2. This completely fulfilled our expectations:<\/p>\n<div id='gallery-2' class='gallery galleryid-7258 gallery-columns-1 gallery-size-full'><figure class='gallery-item'>\n\t\t\t<div class='gallery-icon

physical parameters are not yet entirely certain, coils and transformers are particularly suitable for self-winding. This offers the opportunity to replace or modify windings or toroidal cores, or generally adapt them to the final required parameters. This example demonstrates once again that a DIY solution is by no means inferior to an industrially manufactured component. Furthermore, the existing transformer is even more cost-effective than a store-bought equivalent.<\/p>\n<p>If you have any questions about our solution or need support with a similar project, please contact us!<\/p>\n<p>&nbsp;<\/p>","protected":false},"excerpt":{"rendered":"<p>Bei einem unserer aktuellen Entwicklungsprojekte war es notwendig einen Transformator zu finden, \u00fcber den Signale breitbandig in eine Schaltung eingekoppelt werden k\u00f6nnen.
