Tektronix vs. Keysight at PCIM: Two Ways to Look Inside a SiC MOSFET

Tektronix vs. Keysight at PCIM: Two Ways to Look Inside a SiC MOSFET

Two booths at PCIM. Two oscilloscope giants. Both measuring SiC MOSFETs — but asking entirely different questions. This is what the Tektronix/Keithley vs. Keysight split reveals about where SiC technology...

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...

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...

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.

SiC MOSFET Power Characterization at PCIM: Why Static and Dynamic Are Two Different Worlds

SiC MOSFET Power Characterization at PCIM: Why Static and Dynamic Are Two Different Worlds

Two stations. Two measurement worlds. Tektronix and Keithley showed at PCIM why static DC characterization and dynamic switching power testing are not the same thing — and why SiC MOSFET...

Adaptive Gate Current Shaping: How Bosch EG120 Solves the Parallel SiC-MOSFET Balancing Problem

Adaptive Gate Current Shaping: How Bosch EG120 Solves the Parallel SiC-MOSFET Balancing Problem

Two SiC MOSFETs in parallel will never have exactly the same threshold voltage. That nanosecond difference creates transient current imbalance that degrades reliability over a vehicle's lifetime. The Bosch EG120...

Wolfspeed Gen 4 SiC MOSFET at PCIM: 30–50% Less Turn-On Loss — But What Are You Actually Measuring?

    Wolfspeed Gen 4 SiC MOSFET at PCIM: 30–50% Less Turn-On Loss — But What Are You Actually Measuring?

    Gen 4 delivers 30–50% lower turn-on switching losses. That's the claim. At PCIM, Wolfspeed backed it with a live oscilloscope comparison — three devices, same loop, same conditions. Here's what...

    Power Integrity at PCIM: What OMICRON Lab and Picotest Were Really Asking

    Power Integrity at PCIM: What OMICRON Lab and Picotest Were Really Asking

    "Is your test bench complete?" That was the question on the wall at the OMICRON Lab and Picotest booth at PCIM. Four live demos — loop gain, output impedance, PSRR,...

    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...
