USRP를 할당 한 후 파형 xml 파일에 적절한 코드를 삽입하여 USRP의 dataShort_out을 DataShort 같은 DataShort 입력 포트에 연결합니다. 그러나이 포트를 모니터링하면 할당을 찾을 수 없습니다. 잘 작동합니다. 모니터 포트 패널에서 : Call/s = 약 30; MB/s = 0; 요소/s = 0; 평균 대기열 부서 = 2 % 시간 = 0; 추가 내 파형의 sad.xml을 찾을 :USRP_UHD가 데이터를 제공하지 않습니다

내가 운이없이 Redhawk이 1.9에서 문제를 재현하기 위해 노력했다. 필자는 첫 번째 DataConverter 구성 요소를 제외하고 파형에서 모든 연결 및 구성 요소를 제거하여 파형을 단순화했습니다. 나는 또한 USRP_UHD 할당과 USRP_UHD와 DataConverter 사이의 연결을 유지했다. 이것은 제거 된 구성 요소로부터 잠재적 인 문제를 도입하지 않고 USRP_UHD 장치에 중점을 둡니다. 내 테스트에서 데이터는 예상대로 DataConverter를 통해 USRP_UHD 장치에서 이동합니다.

당신이 어떤 포트를 모니터 않았다 다음 USRP_UHD의 dataShort_out 포트를 다음 산출 모니터링? 이 값은 선택된 샘플 속도가 250 kHz이고 각 샘플이 두 개의 short int요소으로 구성되어 있다는 것을 고려하면 합리적입니다.

이전의 파형을 단순화하고 문제가 계속되는지 확인하는 것이 좋습니다. 파형이 시작된 후 시작하는지 확인하십시오. USRP_UHD의 dataShort_out 포트를 모니터하고 위에 게시 한 것과 결과를 비교하십시오. 값이 비슷한 경우 제거한 구성 요소 중 하나가 원인 일 수 있습니다.

환경에 대한 일부 추가 정보는 문제를 확인하는 데 도움을 줄 수도 있습니다. 어떤 버전을 사용하고 있습니까 (OS, Redhawk, FrontendInterfaces, USRP_UHD 등). USRP의 어떤 모델을 사용하고 있습니까?
