描述

新的Agilent E4438C ESG矢量信號發(fā)生器通過提供優(yōu)異的基帶信號而達(dá)到了新的性能水平。它具有寬RF調(diào)制帶寬、快采樣率和大存儲器，這是評估2.5G、3G和寬帶無線通信系統(tǒng)及部件的關(guān)鍵要求。此外，ESG矢量信號發(fā)生器還提供達(dá)6GHz的頻率覆蓋，能符合無線局域網(wǎng)的特殊要求。

儀器可提供模擬調(diào)制、采用標(biāo)準(zhǔn)和定制制式的數(shù)字調(diào)制、優(yōu)異的電平和頻譜純度，以及極便于配置的體系結(jié)構(gòu)，因而是一般研制開發(fā)、制造和查錯應(yīng)用的理想設(shè)備。
