linearity test signal 中文意思是什麼
linearity test signal
解釋
線性測試信號-
The results of the test demonstrated that the system has a good performance in the linearity, dynamic scope, isolation, coherence of the amplitude. the group delay of the upmixers is 2ns, which is better than other domestic manufactures. because the inconsistency between the isolation and the phase coherence, and the error of the test method, we haven ’ t gotten the good performance of the phase coherence. the next work is improving the restrain of the filter to the lo signal and the phase test methods
在單路發射通道上，群時延達到了2ns ，優于國內很多產品。三路通道之間的相位一致性由於測試方法的誤差以及隔離度指標的牽引作用，我們不能調試達到非常好的在相位一致性指標，再下一輪的工作中必須提高濾波器對本振信號的抑制度，改進相位測試方法以達到指標要求。
