PPA4500은 고속 FPGA / DSP 샘플링 기술과 N4L의 존경받는 “Planar Shunt”기술을 특징으로하는 PPA4500은 12 년 이상의 개발 결과입니다. PPA4500은 향상된 PPA2500 및 PPA2600 모델을 향상된 정확도, 컬러 TFT, 전면 USB 포트 및 빠른 처리로 대체합니다. PPA4500은 정확성과 기능면에서 획기적인 도약입니다. PPA4500은 변압기 손실 테스트, PWM 인버터 드라이브 효율 테스트, IEC62301 / EN50564의 대기 전력 테스트 및 더욱 까다로운 애플리케이션에 적합합니다.

PPA4500은 기본 주파수를 최대 2MHz까지 측정 할 수있을뿐 아니라 동일한 2MHz 주파수 상한으로 최대 100 고조파까지 측정 할 수 있습니다. PWM 모터 드라이브 모드는 엔지니어가 복잡한 고조파 왜곡 된 파형을 측정하도록 계측기를 신속하게 설정할 수있게 해주는 정교한 신호 처리 알고리즘으로 PWM 신호의 높은 샘플 속도 (2Ms / s) 트루 밴드 (2Mhz) 분석을 용이하게합니다. PPA4500 측정 된 데이터의 대역폭에 영향을주지 않으면 서 기본 주파수 동기화를 위해 병렬 디지털 필터링을 사용합니다.
