| HF Conducted emissions - Spectrum analyzer |
| (1/1) |
| mattko:
Hello, I'm doing pre compliance for conducted emissions and the measurements at high frequencies (80 MHz - 108 MHz) are lower, comparing to measurements done at a certified laboratory. From your experience, which things affect measurements at these frequencies? I tried the spectrum analyzer at the certified laboratory and it performed the same as their SA, so the problem should be in our test setup. I'm using a 12 V battery, 5uH LISN, short cables from LISN to DUT, GND plane under DUT (same distance to DUT), R&S SA Any ideas would be welcome! |
