Unfortunately, companies use Microsoft Word frequently to write reports. Word has basic support for Tables of Contents, Cross-Referencing, and Captions for Images and Tables, which Word refers to as fields. One issue is that Word does not update the fields automatically without requiring user interaction. I use an application called […]

To more accurately measure emissions from a DUT (Device Under Test), it is wise to calculate the path loss, or cable loss, from the receiving device, whether that is a LISN, a Current Clamp, or an antenna. We can do this by using the tracking generator on the EMI receiver […]
Farads (F) is the standard unit of capacitance in the International System of Units (SI). One farad is a massive unit of capacitance, representing the ability of a capacitor to store one coulomb of electrical charge with a potential difference of one volt between its plates. Given the enormous range […]
I don’t like programming, I am not very good at it; yes I can do just enough to make Arduino’s talk SCPI and do other things for me. However, I dislike writing reports in Microsoft Word more (don’t get me started on my feelings about Microsoft Windows). This is where […]
Plotting EMC limit charts in Microsoft Excel is unfortunately quite hard, Standards like CISPR 11 and CISPR 25 make use of Log/Log graphs.
After AC Rectification, the next step is Reducing the Ripple on the DC supply line as much as possible.
One of the standard tests for EMC testing is ESD Testing, It is one of the tests worth doing first, so if you fail this test, you haven’t spent all that much time or money on testing. In most cases, you will be looking at “IEC 61000-4-2: Electromagnetic compatibility (EMC) […]
If I were to advise someone just starting in the field of EMC today, the advice I would give them would depend on what field they wanted to go into and their background. I didn’t plan to go into EMC testing or Engineering. I started at CASS Industries in 2014 […]
When I was working for ARRIVAL, setting up the Automotive EMC lab there, I needed an ISO 10605 Annex F island as part of the ESD test setup. This test setup is as far as I am aware unique to Automotive, and as such commercial EMC Technicians and Engineers are […]
In the United Kingdom, if you want to place a product on the market you need to ensure that you have a CE mark, this is fundamentally the same as the now deprecated UKCA mark. The CE mark will allow you to sell in Europe. Please see this post about […]
Every so often we see online stories of a “fake” phone charger burning down a home or giving people electric shocks. Normally these phone chargers are referred to as ‘Apple’ or ‘iPhone’ chargers, however, that is just because the small triangle chargers (in a variety of colours) are so prevalent. […]
