ETTUS RESEARCH Board Mounted GPSDO (OCXO) Recommended for USRP X300/X310  783173-01

Produto Lacrado de Fábrica

Este é um oscilador de cristal oven-controlled (GPSDO) disciplinado por GPS, compatível com USRP X300 ou X310. O GPSDO fornece uma referência de 10 MHz de alta precisão e um sinal de 1 PPS.
Isso permite que os desenvolvedores criem sistemas que atendam a aplicativos com requisitos rígidos de sincronização ou alinhamento de tempo global dentro de 50 segundos.
