· In추가, 8947은, 내부앞앰프 픽업·센서를 지원하는 BNC 터미널을 장비하고 있습니다.통상의 압전기의 가속도 픽업 뿐만이 아니라 내부앞앰프를 갖춘 전압 출력 가속도 픽업도, 8947에 직접 접속할 수 있습니다.그것은 전 앰프 오퍼레이션에 정전류 전원을 공급합니다.
· 전압 신호 입력을 제공하는 가속도 픽업 신호에 가세하고, 8947은 한층 더 통상의 전압 신호를 측정할 수 있습니다.
· 내부 anti-aliasing 필터 8947은, 진동 파형상에서 FFT 분석을 행하는 경우, 불가결의 anti-aliasing 필터를 장비하고 있습니다.
· 8947은 다음의 어플리케이션을 위해서 사용할 수 있는:측정하는 엔진 진동, 셀식 전화, CD플레이어 진동 시험중에 바이브레이터의 진동을 측정하는 관계 진동을 측정하는 펌프 진동을 측정하는 브레이크 진동의 측정...또 다른 타입의 진동 내구성 테스트 |
