* 产品描述

产品描述:

R&S ESW26来自Rohde & Schwarz,是一款工作频率为1 Hz至26.5 GHz的EMI测试接收器。该仪器旨在提供快速可靠的认证测量,同时保持出色的射频特性、高动态范围和测量精度。它符合 CISPR、EN、MIL-STD-461、DO-160、ANSI、ETS、VCCI 和 FCC 安全和 EMC 标准的最严格要求。EMI 测试接收机集成了 21 个预选滤波器(高通和陷波)、一个前置放大器级和一个脉冲电流限制器。除了在开发过程中进行 EMI 分析外,它还可以用作信号和频谱分析仪,并在频谱分析仪模式下执行符合标准的 EMI 测量。

除了传统的阶梯扫描模式外,R&S ESW26 还使用基于 FFT 的时域扫描 (TDS),虚拟步长为分辨率带宽的四分之一,FFT 窗口重叠超过 90%。这导致了 CISPR 16-1-1 所需的高频分辨率和超快速测量。它利用最佳预选滤波器来抑制强带外信号,以便在通带内进行高灵敏度测量。它还具有一个前置放大器,以进一步提高灵敏度,并结合一个可切换的脉冲限制器,以保护第二个抗脉冲射频输入免受高能量信号的影响。

特点:

 

频率范围 2 Hz 至 26.5 GHz

符合 CISPR16-1-1、ANSIC63.2、MIL-STD-461 和 FCC 标准

最高的动态范围和最高的精度,适用于要求苛刻的认证测量

使用基于 FFT 的时域扫描进行超快速测量

使用 ISM 频段的可选高通滤波器和陷波滤波器进行预选

EMI 测试接收机和信号与频谱分析仪集于一身

详细信息

Product Description:
 
The R&S ESW26 from Rohde & Schwarz is an EMI test receiver operating from 1 Hz to 26.5 GHz. The instrument is designed to provide fast and reliable certified measurements while maintaining excellent RF characteristics, high dynamic range and measurement accuracy. It meets the most stringent requirements of CISPR, EN, MIL-STD-461, DO-160, ANSI, ETS, VCCI and FCC safety and EMC standards. The EMI test receiver integrates 21 preselected filters (high pass and notch), a preamplifier stage, and a pulse current limiter. In addition to performing EMI analysis during development, it can also be used as a signal and spectrum analyzer and perform standards-compliant EMI measurements in spectrum analyzer mode.
 
In addition to the traditional step scan mode, the R&S ESW26 uses FFT-based time domain scanning (TDS) with virtual step sizes of one-quarter of the resolution bandwidth and FFT window overlap of more than 90%. This results in the high frequency resolution and ultra-fast measurements required by CISPR 16-1-1. It utilizes an optimal pre-selected filter to suppress strong out-of-band signals for high sensitivity measurements within the passband. It also features a preamplifier to further increase sensitivity, combined with a switchable pulse limiter to protect the second anti-pulse RF input from high energy signals.
 
Features:
 
Frequency range 2 Hz to 26.5 GHz
Comply with CISPR16-1-1, ANSIC63.2, MIL-STD-461 and FCC standards
Highest dynamic range and highest accuracy for demanding certification measurements
Ultra-fast measurements with FFT-based time domain scanning
Use the selectable high-pass filter and notch filter in the ISM band for pre-selection
EMI test receiver and signal and spectrum analyzer all in one
