Rohde & Schwarz introduces a probe with both a large offset range and a DC voltmeter for power integrity measurements. The R&S RT-ZPR20 is a new, extremely low-noise power rail probe with a bandwidth of 2 GHz. Its 1:1 attenuation also ensures very good sensitivity. The large offset range of ± 60 V permits analysis of the smallest disturbance signals during power … [Read more...]
Troubleshooting EFT
EFT Phenomenon Recently I tested a medical device for EFT susceptibility. The requirement is that the medical device must be immune to EFT bursts generated per IEC 61000-4-4. Per this standard EFT bursts are applied in four steps. For level 4, steps 1 and 2 are +/-2kV at 5kHz, and steps 3 and 4 are +/-2kV at 100kHz. For each step, these bursts are applied at 300ms interval for … [Read more...]
