R&S?ESPI 測試接收機

 提示:點擊圖片可以放大
R&S®ESPI 測試接收機專門為滿足產品開發和 EMC 預認證過程中所有的 EMC 測試需求而設計,頻率范圍 9 kHz ~ 3/7 GHz,當配備 R&S®ESPI-B2 預選器/前置放大器時,所有 R&S®ESPI型號都具有出色的動態范圍,因而能根據 CISPR 16-1-1 對脈沖重復頻率 ≥ 10 Hz 的信號執行準確干擾測量。它們還可以使用 R&S®ESPI-K50 選件測量通訊或廣播網絡的場強覆蓋,而且測量精度非常高。

主要特點
• 預認證 EMI 測試接收機和高品質頻譜分析儀合二為一
• 集成預選功能,可選擇 20dB 前置放大器(R&S®ESPI-B2 選件)
• 滿足新版CISPR 16-1-1的加權檢波器,包括 CISPR-Average 和 RMS-Average
• 場強特性評估的測量速率非??欤≧&S®ESPI-K50 選件)
• 可利用自動和交互測試程序快速、可靠地進行測量
• 預定義修正因子
• 提供民用標準的限值庫
• 另有帶寬在 5.6 MHz 和 8 MHz 之間、符合 DVB-T/T2 地面 DVB 網絡標準(R&S®ESPI-K50 選件)的各種信道濾波器。
