MODULATED POWER AMPLIFIER / TBMDA4

범용 Power Amplifier,Near-field Probe용 증폭기,TEM Cell용 증폭기 TBMDA4 변조 광대역 전력 증폭기는 전자 빌딩 블록 및 제품의 내성 테스트를 위한 신호 소스를 생성하는 증폭기로, 내장된 변조기능을 통해 1kHz의 AM,PM신호를 생성하게 합니다. 스펙트럼 분석기의 트래킹 제너레이터 출력에 의해 구동되도록 설계되었습니다.
<주의사항!!>
1. 절대 TBMDA4를 스펙트럼 애널라이져 입력단에 직접적으로 연결하지 마세요.
2. 스펙트럼 애널라이져의 입력단 Spec을 확인하시고 알맞은 감쇄기를 장착 후 연결하시길 바랍니다.
3. 스펙트럼 애널라이져의 RF 출력 포트를 열거나 단락시킨 상태에서 구동하지 마십시오.
