說明

實用，價格適中，從不粗心

頻率穩定度：0.025ppm

如今，無線通信應用無處不在。頻譜有限的信號變得非常擁擠。因此，對信號效率和頻率穩定性的要求越來越高。為了滿足高精度測量要求，GSP-9300B提供了0.025ppm的頻率穩定性和1ppm /年的老化率，這僅在高端T＆M設備中出現。

內置前置放大器

在產品開發階段，工程師經常面臨測量小型RF信號的挑戰。GSP-9300B的內置前置放大器可提供-149dBm的基本噪聲。與內置EMI濾波器和專用EMI近場探頭搭配使用時，GSP-9300B可以進行EMI測試和調試。

超過20種測量應用

GSP-9300B提供了豐富的信號處理功能，包括AM / FM調製信號分析，信號通道分析和CATV參數測試，信號穩定性的特性測試以及組件的頻率響應或功率線性測試，從而大大提高了測量的便利性。大多數同類競爭對手僅提供一些測試功能，而GSP-9300B的標準內置功能是競爭對手的選擇。
