Testing Automotive Radar in an EMC Storm: What Happens When 77 GHz Meets Interference
A speedometer showing radar-detected velocity — in real time, under active EMC interference. The R&S automotive radar testing demo at Cologne closed the gap between functional radar validation and EMC...
Know the Limits of Your Own View: Spectrum Monitoring and GNSS PNT Verification at EuMW 2026
Two Keysight stations at EuMW 2026 dealt with the RF world outside the lab: networked spectrummonitoring at 750 MHz with 100 MHz bandwidth, and GNSS receiver verification against a simulated...
Rohde & Schwarz ZNA at 67 GHz: When 16 Traces Tell You Everything — Except What You Need to Know
Sixteen traces. Four Smith charts. Full S-parameter matrix from 10 MHz to 67 GHz. The R&S ZNA screen at the microwave show looked like everything you'd need. Here's what it...
Keysight UXA + VDI WR 6.5 at 140 GHz: What a 16-QAM Constellation Actually Tells You
The center frequency read 140.171752297 GHz. 16-QAM. 500 MHz symbol rate. 2 Gbps raw data rate. At the microwave show in the Netherlands, Keysight's UXA and a VDI WR 6.5...

Synchronized, Automated, Multi-Band: The Keysight Approach to EMC and Wireless Coexistence Testing
869 MHz and 2.4 GHz monitored simultaneously, time-synchronized, with 100% probability of intercept and automated test sequencing. The Keysight multi-instrument coexistence demo at Cologne explained what it takes to validate...
Kelvin Measurement Explained: Why 4-Wire Sensing Is Essential for Milliohm and Micro-Ohm Precision
Measuring milliohm resistance is not as simple as applying Ohm’s law. At this level, lead resistance and contact effects dominate the result. Kelvin (4-wire) measurement eliminates these errors and enables...
Keysight Sub-THz Device Analysis at 307 GHz: How University of Stuttgart Is Building 6G IC Test Infrastructure
Center frequency: 307 GHz. Modulation bandwidth: 40 GHz. Residual EVM target: less than 1%. At the microwave show in the Netherlands, Keysight's Sub-THz Device Analysis bench — built with VDI...

The Microwave Oven on the Test Bench: What 225 MHz Real-Time Bandwidth Is Actually For
A microwave oven generates multi-decade, multi-mechanism EMI — from TRIAC switching harmonics at 150 kHz through magnetron broadband emission at 2.45 GHz and beyond. The TDEMI G Series at 225...

Reading the Manual vs Reading the Trace: Anritsu's AI-Powered VNA at 220–330 GHz
At EuMW 2026, Anritsu showed its Tensor VNA, billed as the first AI-powered VNA, running a WR-3.4 thru from 220 to 330 GHz. Today the assistant reads the manual: setup,...
MACOM and NI at the Microwave Show: From 250W GaN to 140 GHz SDR — What a "Complete System" Actually Looks Like
Two booths, 40 meters apart. MACOM with 250W GaN and 60 dBm limiters. NI with a live 140 GHz SDR link across 40 cm of free space. Neither was showing...
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,...

One Pulse, Three Sensors: What a Synchronised Power Measurement Reveals About an Amplifier’s Tail
At EuMW 2026, Anritsu showed a bi-directionalcoupler with three synchronised peak power sensors on a pulsedamplifier. The ratio between the channels held at 19.741 dB while theabsolute values drifted. The...
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.

Two Oscilloscopes, One Wolfspeed Board: How Keysight Tackles the High-Side Measurement Problem at PCIM
One Wolfspeed SiC evaluation board. Two Keysight oscilloscopes — 1 GHz 14-bit on the left, 6 GHz 16-bit on the right. Same DUT, different measurement questions, different instrument tiers. The...
Rohde & Schwarz Wideband Modulated Load Pull: The Test That Deliberately Breaks Your Amplifier
Load pull testing deliberately varies impedance away from the ideal operating point — until the amplifier's behavior is fully mapped. At the microwave show, R&S showed why wideband modulated load...
