While there are a number of affordable spectrum analyzers available to the product designer or EMC engineer, such as the Rigol DSA800-series or Siglent SSA3000X-series, I discovered an extremely low cost analyzer useable for general-purpose EMI troubleshooting. This tiny module (Figure 1) is actually a high quality software defined radio (SDR) that can tune from 24 … [Read more...]
Welcome to Mega Automotive
by Joanna Hill Today is Arnold’s first day at Mega Automotive. He is fresh out of college with an electrical engineering degree and is eager to meet his new boss, Mr. Buttsworth. Mr. Buttsworth: Hello Arnold welcome to Mega Automotive. I’m sure you’re going to like it here. It’s a fast-paced environment with lots to learn and loads of good people to work … [Read more...]
The Annual IEEE EMC Show – Why Dresden? Plus Proof of the Arbitrary Selection of Automotive Amplifier Harmonic Limits
Read other posts in the "Elephant in the Test Room" series here.It is looking good for using 3D software to diagnose the performance of the radiated emissions test fixture. Should get the go ahead any day now. Meantime, let’s explore this year’s hot topic. The Annual IEEE EMC Show - Why Dresden?It is no surprise that some USA residents in the EMC industry are wondering why the … [Read more...]
