選用二手測量儀器的優勢是：
1、與新購儀器幾個月的供貨期相比，購買二手儀器的供貨期要短的多。在時間就是市場的今天，優勢無疑是最為明顯的。
2、二手儀器的價格便宜，基本為新購儀器價格的20%～50%。在電子技術迅速發展的今天，儀器的更新也在加快，投資越少則風險越小。
3、為了讓您放心地使用我們提供的二手儀器，我們銷售的二手儀器可以做到：
1、保修半年至一年不等。
2、可以根據您的要求，將儀器送至國家級計量測試單位進行校準。
The R3765CG/R3767CG network analyzers are vector network analyzers that incorporate a new RF circuit analysis technique. The measuring frequency range is from 300 kHz to 3.8 GHz (R3765CG)/300 kHz to 8 GHz (R3767CG). ADVANTEST's unique high-speed signal processing technology enables a faster measurement speed. In addition to the basic model, a model with built-in bridge transmission/reflection characteristic measurement and a model with a built-in S-parameter test set for forward and reverse measurement are also available. An optional 3-port test set or 4-port test set can be added to these models. By installing additional input channels in the receive section, the multi-port models allow perfectly simultaneous measurement of two different measurement paths, revolutionizing the measurement efficiency of multi-port devices
