    • 빠른 전환 펄스는 단일 순간에 광범위한 스펙트럼 신호로 전송 경로, 장치 또는 네트워크를 자극할 수 있습니다. 이러한 펄스는 우리가 수행해야 하는 많은 고속 광대역 측정에 매우 유용합니다. 예를 들어 시간 영역 반사 측정, 반도체 테스트, 기가비트 상호 연결 및 포트 테스트, 레이더 등에서 사용됩니다.

    특히 차동 고속 ​​데이터는 디지털, 컴퓨팅, 상호 연결 및 통신 시스템의 측정 문제가 많았습니다. 놀랍게도 많은 문제를 해결하고, 비용 효율적이고 빠른 전환이 가능한 차동 펄스 발생기는 지금까지 찾기가 매우 어려웠습니다!

    일반적인 응용 분야:
  • TDR/TDT network and match analysis
  • Spectral and flatness measurements
  • Timing, jitter and crosstalk determinations

    • PG900 펄스 발생기는 이러한 다양한 응용 분야에서 PicoScope 9300 20GHz 샘플링 오실로스코프와 함께 사용할 수 있습니다.
