Bode Plot as a Design Tool: How Filter Characterization Predicts EMC Compliance

Bode Plot as a Design Tool: How Filter Characterization Predicts EMC Compliance

One curve, three frequency regions, one answer: does your EMI filter work — and where does it stop working? A breakdown of the Omicron Lab Bode 500 demo from a...

When an Oscilloscope Becomes a Motor Drive Analyzer: The Case for Application-Specific Measurement

When an Oscilloscope Becomes a Motor Drive Analyzer: The Case for Application-Specific Measurement

The MDA 8208HD doesn't call itself an oscilloscope. It's a Motor Drive Analyzer — and that distinction defines everything: 8 channels for three-phase systems, automated harmonic analysis, and correlated time-frequency...

One Signal, Four Perspectives: What a 12-Bit Oscilloscope Actually Shows You

One Signal, Four Perspectives: What a 12-Bit Oscilloscope Actually Shows You

The same signal, four analytical perspectives at once. The Teledyne LeCroy WavePro 804HD-MS 12-bit demo in Turin showed what it means to move from waveform observation to behavioral characterization.

12-Bit Oscilloscopes: When More Resolution Reveals More — and Demands More

12-Bit Oscilloscopes: When More Resolution Reveals More — and Demands More

12-bit resolution gives you 16× more vertical detail than standard 8-bit. But it also amplifies everything your probe introduces. A breakdown of the Yokogawa DLM5058HD demo

When a Spectrum Analyzer Becomes a Surveillance System

When a Spectrum Analyzer Becomes a Surveillance System

At 26.5 GHz with GPS-synchronized direction finding, the FieldFox N9918D is no longer just a handheld analyzer. It's a node in a distributed RF sensing network. Here's what that means...

Why Measuring GaN Switching Is Harder Than Designing It

Why Measuring GaN Switching Is Harder Than Designing It

At high dv/dt and di/dt, measuring GaN switching behavior becomes more challenging than designing it. This article breaks down a complete probe-based measurement system observed at Embedded World 2026.

Signal Integrity Design Validation: Why PCB Structures Must Be Measured, Not Assumed

Signal Integrity Design Validation: Why PCB Structures Must Be Measured, Not Assumed

At GHz speeds, PCB traces are no longer passive wires — they define signal behavior. Here's how vector network analysis makes that visible, measurable, and fixable.

Why Your Signal Problem Is Actually a Power Problem: The Physics Behind SI/PI Coupling

Why Your Signal Problem Is Actually a Power Problem: The Physics Behind SI/PI Coupling

Power noise does not stay in the power domain. It becomes timing uncertainty, which becomes bit errors. At Embedded World 2026, I watched Tektronix demonstrate why signal integrity and power...

De-embedding in High-Speed Signal Integrity: Reconstructing the True Signal Beyond the Measurement Channel

De-embedding in High-Speed Signal Integrity: Reconstructing the True Signal Beyond the Measurement Channel

At Embedded World 2026, Tektronix presented something that did not look like a traditional oscilloscope demo. There was no waveform on a large screen, no eye diagram being explained to...

One Oscilloscope. Four Domains. Why Modern Automotive Debugging Is a System Problem

One Oscilloscope. Four Domains. Why Modern Automotive Debugging Is a System Problem

At Embedded World 2026, one Tektronix demo captured why modern automotive debugging spans four domains: CAN bus, RF/wireless, EMI, and signal integrity — all from a single oscilloscope platform.

High-Speed Interface Testing for DDR and USB: When Digital Signals Become Analog

High-Speed Interface Testing for DDR and USB: When Digital Signals Become Analog

At DDR5 speeds, one bit lasts 156 picoseconds. At this scale, there is no digital — only analog behavior. At Embedded World 2026, I watched what it takes to keep...
