模擬信號發(fā)生器 MG3740A 具有出色的射頻性能，包括單邊帶相位噪聲、輸出電平等等，同時具有豐富的調(diào)制功能 (調(diào)頻/調(diào)幅/調(diào)相/脈沖)。MG3740A 作為一款高純度的信號源，是用來測試模擬射頻接收機的理想選擇。此外，添加數(shù)字調(diào)制選件后可支持窄帶數(shù)字調(diào)制信號的生成。
MG3740A 支持窄帶數(shù)字調(diào)制、連續(xù)波和模擬調(diào)制。

擴展選件
添加額外模擬調(diào)制輸入［選件］:
添加額外模擬調(diào)制輸入選件，擴展到兩個內(nèi)部調(diào)制源 (調(diào)頻/調(diào)幅/調(diào)相) 和一個外部調(diào)制源，從而支持同步的雙音調(diào)制信號輸出。
支持兩路獨立的射頻輸出［選件］:
支持“用于接收機特征測試的有用信號 + 干擾信號"、“放大器交調(diào)特征評估"和“用于混頻器評估的射頻/本振信號源"。
USB 功率探頭 (單獨出售):
最多支持連接兩個 USB 功率探頭
擴展到窄帶數(shù)字調(diào)制信號發(fā)生器［選件］:
添加數(shù)字調(diào)制功能［選件］后可支持窄帶數(shù)字調(diào)制信號的生成。
