□ EMC (Electromagnetic Compatibility) 측정관련하여 주로 사용하는 로데 앤 슈바르츠 회사의 EMI Test Receiver로써, 제품 개발시 요구되는 EMI 규격의 Precompliance test 및 디버깅용도로 활용하는 장비
CISPR 규격의 Quasi Peak와 Average측정이 가능함.
□ 구성
- ESPI3 : EMI Test Receiver 9 kHz to 3 GHz, for precertification to commercial standards
- ESPI-B2 (option) : Preselector and preamplifier for R&S®ESPI3, factory installation
- MDS21 : Absorbing clamp 30 to 1000 MHz, 50 Ohm
□ 성능
- Frequency Range : 9kHz ~ 3GHz
- Peak, Quasi-Peak, Average, CISPR Average, RMS and RMS Average (max. 3 detectors simultaneously)
- EMI measurement bandwidths 200 Hz, 9 kHz, 120 kHz, 1 MHz
- Correct pulse weighting in line with CISPR 16-1-1 from 10 Hz pulse repetition frequency
- For all commercial EMI standards such as CISPR, EN, ETS, FCC, ANSI C63.4, VCCI and VDE
- Option ¸ESPI-B2 : Preselector and 20 dB preamplifier
- Resolution bandwidths from 10 Hz to 10 MHz (in 1/3/10 sequence)
- RMS detector for measurements on digitally modulated signals
- Test routines for TOI, ACPR, OBW, amplitude statistics
□ 제품개발시 EMI 규격 관련 측정을 하는데 사용
- Conducted emission 150kHz~30MHz 측정(with ENV216)
- Disturbance power 30MHz~300MHz 측정 (with MDS21)
- Radiated emission 30MHz~1GHz 측정(with RF Amtenna)
