범용 펑션 제네레이터 (TOE 7704 ... 7711)
- 상세 설명
TOE 7700 시리즈의 함수 발생기는 완전히 아날로그 디자인의 제품입니다.
가변 신호 대칭을 포함한 일반적인 표준 신호 모양 외에도 이 범위에는 가장 까다로운 사용자를 만족시켜야 하는 lin/log 스윕 발진기가 장착되어 있습니다. 연속 또는 트리거된 스위핑을 선택할 수 있으며, 하한 및 상한 스위프 한계는 물론 별도로 조정할 수 있으며 스위프 주파수는 통합 주파수 카운터에 의해 정확하게 표시됩니다.
많은 세부 사항은 회로 기술의 최신 발전을 반영합니다. 출력 주파수 및 스위프 시간을 조정하기 위한 마모 없는 스핀휠, 상호 계산 방법을 사용하는 내부 또는 외부에서 사용 가능한 주파수 카운터, 이전에 얻을 수 없었던 신호 품질을 허용하는 정교하고 새로운 스위칭 기술입니다.
모든 입력 및 출력은 유동적이며 가장 중요한 것은 조작의 용이성을 위해 전면 패널에 배열되어 있습니다. 넓은 주파수 범위, 뛰어난 처리 품질, 제어판의 명확하고 균형 잡힌 디자인은 이러한 함수 발생기의 개념을 완성합니다.
TOE 7706, TOE 7708 및 TOE 7711/7711 모델은 신호 트리거링 및 게이트 모드도 제공합니다.
TOE 7711/7711 마이크로프로세서 제어 합성기/함수 발생기는 범용 함수 발생기를 특징짓는 다양한 기능과 최신 합성기의 안정성을 결합합니다. PLL 모드에서 출력 주파수는 10Hz ~ 44MHz 범위에서 수정 정확도로 제어됩니다. 기본 정확도는 전체 스케일 값의 2 x 10-6이고 노화 속도는 2ppm/년에 불과합니다.
