Designing good enough Near Field Probes

Ey reader! Most of the times, we take for granted the complexity of things we use every day. One example is Near-Field Probes There are many out there, from 10 € to 2000 €. They all seem to work in the same way: Connect them to an oscilloscope or a Spectrum Analyzer Place them close to an alternate source of Electromagnetic Energy Measure and extract conclusions Easy, right? What if I ask you to build one or two from scratch? ... Not that easy, right? That exactly happened to me when I...

Hardware Startups have it 10x harder to sell a hardware product Why? First, they have the typical challenges of a Startup Limited amount of resources: you cannot build a 1M laboratory the first week. The stereotype photo of the first days of a Startup has their founders working long hours in the garage of one of them. You need to build something great with the tools you have around and if you are lucky, with some tools you receive from generous donors. Pressure from investors to get high...

It is the moment to change our approach In the previous issue, we talked about the need for tools. You can read it, and all the other issues, here. We want to go to the moon, and Mars, make space trips as regular holidays We want to have fully autonomous cars and have 0% accidents We want to watch HD Netflix from any remote village But We use our grandpa´s multimeters We keep old versions of our CAD tools We follow the waterfall project management process And we are surprised that... We will...

Give tools to your team

Give tools to your team Every manager has one directive: do your best while spending the least. The problem? Spending the least can prevent your team from doing their best. If you are a founder with a software background, hardware might seem prohibitively expensive to you. Wise managers think, What is the minimum I can spend to enable my team to perform their best? If they ask their technical team, they will receive a long list of tools and gadgets, each justified as indispensable.Some of...

One of the most common questions I get when talking about certifications and selling devices in the European Union is: — “Ignacio, how do I know which requirements apply to my device?” To be fair, the information out there is often blurry—if not outright contradictory and confusing. As a manufacturer, you should focus on the Radio Equipment Directive (RED). Navigating the RED directive Why is it needed? The Radio Equipment Directive (2014/53/EU) regulates the placement of radio equipment on...

Hi there, You might know, I have been working on a new guide about Near-Field probes. Learnings so far Writing long content requires time, a lot of time It is hard to fight the impostor syndrome until one day you say "Screw it", I am publishing it now There are a lot of popular assumptions (i.e. Near-Field probes are easy to use) that, once you scratch the surface, they are not true What it is in for you You can directly download the guide using this link: download Near-Field Probes guide...

Hi! Today´s email is the email sequence that new subscribers receive when they sign-up. You are already subscribed, so it would not be fair to leave you without it. What is in? EMC should not be difficult and boring Why bother with EMC (Electromagnetic) Energy comes and go EMC should not be difficult and boring Since my first job in electronics, I have been told that Electromagnetic Compatibility (EMC) is hard. And that’s it. No more details, no more explanations. When digging more, what I...

Hi reader, Your interest in the content I prepare makes me very happy. The last week I went to the EMC Europe, in Belgium, and I got very positive feedback. Making things simple pays off, so I am planning the next experiments on conducted and radiated emissions. Today´s chapter is very short. I wanted to share a few points with you. Downloadable guide The guide on current probes can be now downloaded in PDF format. You can get it from the downloads website. Can you make me a favor? If we have...

The shopping list for DC Conducted Emissions pre-compliance testing by Ignacio de Mendizabal, 14/8/2024 Hello Reader, Happy to have you here Today, we will prepare everything we need to measure DC conducted emissions using Line Impedance Stabilization Networks (LISN). We will use two of the most affordable models and you will eave this chapter with a shopping list with all the components. Standards There are many different standards defining the test set-ups, limits and frequency bands. For...

Current probes Everything you need to start using them for EMC troubleshooting by Ignacio de Mendizabal, 22/07/2024 Hello reader, Glad to have you here with me, talking about electronics. Welcome. If you are new with me, I am Ignacio, and I want to stop EMC being a problem. I want to make it so easy that people forget about it. Look, I have never been a fan of the sentence “that is not my job”. I hate it. It is the opposite of the drive, resilience and hard work philosophy that I try to...
