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...

510 MHz Real-Time: How IQ Capture Changes the Logic of EMI Measurement
Traditional EMI testing produces a result. Real-time IQ capture produces a dataset. The Gauss Instruments TDEMI S — 510 MHz capture bandwidth, density display, full replay — explains what that...
