R&S®ESPI 测试接收机

 提示:点击图片可以放大
R&S®ESPI 测试接收机专门为满足产品开发和 EMC 预认证过程中所有的 EMC 测试需求而设计,频率范围 9 kHz ~ 3/7 GHz,当配备 R&S®ESPI-B2 预选器/前置放大器时,所有 R&S®ESPI型号都具有出色的动态范围,因而能根据 CISPR 16-1-1 对脉冲重复频率 ≥ 10 Hz 的信号执行干扰测量。它们还可以使用 R&S®ESPI-K50 选件测量通讯或广播网络的场强覆盖,而且测量精度非常高。

主要特点
• 预认证 EMI 测试接收机和高品质频谱分析仪合二为一
• 集成预选功能,可选择 20dB 前置放大器(R&S®ESPI-B2 选件)
• 满足新版CISPR 16-1-1的加权检波器,包括 CISPR-Average 和 RMS-Average
• 场强特性评估的测量速率非常快(R&S®ESPI-K50 选件)
• 可利用自动和交互测试程序快速、可靠地进行测量
• 预定义修正因子
• 提供民用标准的限值库
• 另有带宽在 5.6 MHz 和 8 MHz 之间、符合 DVB-T/T2 地面 DVB 网络标准(R&S®ESPI-K50 选件)的各种信道滤波器。
