EMI接收机规范的剖析按定义，任何符合CISPR 16,Part 1要求的设备，都可视为可进行符合性测试的EMI接收机WERNER SCHAEFERHewlett－Packard CompanySanta Rosa，CA大多数的商用EMI标准引用了CISPR Publication 16，Part 1来规范EMI和EMS测试设备。

本文将会讨论最重要的接收机规范，总结预期附加的规范，并且讨论频谱仪用于符合性测试时的一些限制。

正在修订中的CISPR16，part1将技术规范扩展到了1GHz到18GHz。

这也将会在文中讨论到。

CISPR16，Part1目前的版本发布于1993年8月，其中规定了接收机在9KHz 到1GHz的技术规范。

其中包括输入阻抗，检波器特性和中频（IF）带宽形状，同时也规定了测量正弦波和不同重复周期的脉冲信号的幅度精度。

另外，还对接收机的杂散响应，镜像和中频抑制，互调失真以及屏蔽效能有附加的要求。

CISPR16，PART1（08－93）中的接收机规范输入阻抗接收机输入阻抗规定为50Ω，可接受的与正常值的偏离是以VSWR（电压驻波比）的形式给出。

匹配比较好的输入衰减器能够改善接收机的VSWR，因此规范中提出了两种衰减器的设置：0dB和10dB或者更大。

此性能会直接影响EMI测量的总的不确定度。

分辨率带宽在不同的频段测量需要使用不同的分辨率带宽。

一般情况下，通常以带宽（比如3dB带宽）及来描述接收机的中频滤波器性能，其中频率响应是指滤波器的波形因子（比如60dB和3dB带宽比）或者是频响特性必须满足的一个框架（图1）。

CISPR16，PART1中所规定的6dB带宽为：● 200Hz 9KHz至150KHz● 9kHz 150kHz至30MHz● 120kHz 30MHz至1GHz此外，对于每个滤波器，框架通常以相对于滤波器中心频率偏移一定频率值的插入损耗的形式给出。

此框架的规定使中频滤波器的幅度响应特性的定义就更加完整。

Keysight N9038AMXE EMI Receiver–3 Hz up to 44 GHz frequency range–Compliant with CISPR 16-1-1:2010 and MIL-STD-461–± 0.5 dB at 1 GHz amplitude accuracySummary of Key SpecificationsThe X-Series difference Future-readyOptimize your investment and extend instrument longevity with upgradeable processor, memory, connectivity, and more to keep your test assets current today and tomorrow.Consistent measurement frameworkAchieve measurement integrity across your organization and drive more productivity in less time by leveraging a proven foundation for signal analysis and identical operation across the X-Series instruments.Broadest set of applicationsAddress the changing demands of technology with additionalmeasurement applications, the ability to run software inside the openWindows operating system, and a first-to-market track record in emerging standards.Stay ready, stay in sync, and arrive ahead —with the Keysight X-Series./find/X-SeriesKeep the Test Queue FlowingIn EMC testing, success depends on tools that can help you do more in less time—today and tomorrow. That’s why we created the MXE: it’s a standards-compliant EMI receiver and diagnostic signal analyzer built on an upgradeable platform. In the lab and on the bench, it provides the accuracy, repeatability,and reliability you need to test with confidence.The MXE makes it easy to test in accordance with CISPR 16-1-1:2010 and MIL-STD-461. Choose the frequency coverage you need—up to 3.6, 8.4, 26.5, or44 GHz—and fully test devices with outstanding accuracy and excellent sensitivity across the required ranges.Through the front panel or remotely with software, you can evaluate emissions and identify suspect signals using EMC measurements and a variety of intuitive displays. The extensive set of built-in analysis tools helps you diagnose the causes of noncompliant emissions.With all these capabilities and more, the MXE enables you and your team to keep the test queue flowing.Extend instrument longevity with easy upgradabilityTo keep your instrument current and extend its longevity, the MXE offers easy upgradability of hardware and software capabilities. For example, you can enhance platform performance through CPU and memory upgrades, and add functionality with a simple license key.Leverage the proven reliability of a mature hardware platform Uptime is essential in a test lab and that’s why we built the MXE on the robust Keysight X-Series signal analyzer platform. In addition, the MXE carries the benefits of Keysight’s standard three-year warranty and responsive service and support team.The MXE is ideally suited for high-performance EMC testing in commercial and military applications. The instrument offers a range of CISPR- and MIL-STD-compliant capabilities—detectors, bandwidths, and more—as well as features that further enhance the accuracy and throughput of EMC testing and data analysis.Simplify setupThe MXE contains a number of features that simplify the setup process for compliance measurements. For example, you can use setup tables to create specific measurement configurations for a variety of frequency ranges and antennas. You can also reduce overall setup time by saving and recallingfrequently used custom instrument settings. In addition, the MXE can remotely control switching functions in external LISNs.To accelerate identification of suspect emissions, access the built-in library of limit lines and activate the relevant regulatory limits. You can also define custom limit lines with the easy-to-use editor. To ensure appropriate limit testing, the MXE can automatically correct measured amplitudes for specific transducers, antennas, cabling, and external preamplifiers using customer-configured amplitude correction files.Accelerate data collectionThe MXE is designed to help you see signal activity—quickly and easily—from multiple perspectives. The comprehensive user display allows you to see both a broad overview of the emissions environment and a detailed view of the signal amplitude at a single frequency.Easily capture emissions data using built-in automated scan, search, and measure functions that mirror recommended commercial and military testing procedures. The multi-trace and max hold capabilities let you view emissions from the current position of the device under test (DUT) along with themaximum emissions from all DUT positions. During monitoring, the three color-coded detectors are updated simultaneously to ensure accurate results.The MXE receiver display provides a simplified view into the emissions performance of the DUT.Maximize Throughput in Compliance TestingChoose from traditional frequency or rapid time domain scanning.Easily identify suspect signalsWith built-in measurement and analysis functions, the MXE makes it easy to identify suspect emissions. For example, the unique color-coded trace display capability clearly identifies signals that exceed the selected limit lines and margins.When creating suspect lists, you can choose between traditional frequency scanning and rapid time domain scanning. Time domain scans significantly reduce the time needed to create a list of suspect emissions prior to making final measurements.Built-in limit testing makes it easy to create emission suspect lists. The receiver can automatically move out-of-limit signals to the signal list, where you can perform measurements with the touch of a button.Simplify final measurementsThe list function in the MXE makes it easy to perform final emissionsmeasurements for all supported standards. When you need to control tower or turntable position, internal frequency lists can be passed to automationsoftware. When orientation optimization isn’t required, built-in capabilities help you complete final measurements with ease.When final measurements are complete, you can conveniently create reports in HTML or PDF format with customized content that includes amplitude corrections, limits, scan tables, trace data, signal lists, and screen shots.All-digital IF architectureA digital intermediate frequency (IF) receiver architecture improvesmeasurement accuracy. By comparison, an analog IF architecture implements gain blocks, log amps, resolution bandwidths, and detectors with analog hardware. Even the best of these designs exhibit performance differences when receiver settings are changed from the settings used for calibration. These differences are then exacerbated over temperature.The all-digital IF architectureincludes digital realizations of the key components, which operate on the signal after it has been digitized. Digital IF can improve EMC measurement throughput by minimizing the need for users to bring the signal being measured to the top of the reference level. Analog receivers require this step for every measurement to minimize the effects of analog hardware errors.In addition, digital IF architecturereduces the occurrence of IF overload, even if signals are above the reference level.As an EMI receiver and diagnostic signal analyzer, the MXE puts a wealth of capabilities at yourfingertips. New receiver technology reduces measurement time and ensures you are prepared for future requirements.Go faster with time domain scanningThe MXE offers three types offrequency scanning: swept, stepped, and time domain. Time domain scan decreases total test time by reducing overall prescan collection times when longer measurement dwell times are required.Time domain scan speedsmeasurements by using high-overlap fast Fourier transforms (FFTs) tocollect emissions data simultaneously over an acquisition bandwidth that is multiple resolution bandwidths wide. This is in contrast to frequency-domain measurements, whichcollect data in individual resolution bandwidths.With time domain testing, you can collect suspect lists rapidly, greatly improving overall test time and throughput.Automate click measurementsUse the MXE's built-in disturbance analyzer to easily make discontinuous disturbance, or click, measurements as specified in CISPR 14-1. Simplify and automate data collection, analysis, and report generation for these commonly tested emissions for more efficient testing.Enhance Your Lab with the Latest CapabilitiesComparison of resolution and FFT acquisition bandwidths.FrequencyA m p l i t u d eFFT acquisition bandwidthA m p l i t u d eFrequencyReceiver resolution bandwidthSwept or stepped frequency domain scanTime domain scanDwell for each resolution bandwidthDwell for each FFT bandwidth (multiple resolution bandwidth)Simplify and automate data collection, analysis, and report generation for click measurements.Be ready for APD measurementsThe MXE helps future-proof your lab by offering the amplitude probability distribution (APD) function that is being considered by CISPR foremissions testing of microwave ovens. To characterize slowly-varyingemissions, the APD function displays the probability of an emissionreaching or exceeding a given level. To facilitate use of this new function, the MXE also offers specific limit-line types that can be used with built-in evaluation capabilities to simplify DUT testing.Find the maximum with monitor spectrumIn EMC testing, capturing the maximum value of each emissionfrequency is crucial. Doing so enables accurate characterization of the DUT.To ensure that you have identified the frequencies of maximum emissions in your suspect list, the MXE offers a new feature called monitor spectrum. This feature offers both live-spectrum and meter displays that make it easy to see emission levels and find the maximum while adjusting the center frequency. Ultimately, monitor spectrum improves overall measurement time by reducing the time it takes to prepare your signal list for final measurements.Monitor spectrum identifies frequency of peak emissions.Be ready for future applications with the APD function.The global center frequency feature lets you easily track signals in both the receiver and spectrum analyzer.Gain Insight with Extensive Diagnostic CapabilitiesVerifying product compliance is just one facet of EMI testing. Solving emissions problems can present a wide range of challenges, and the MXE offers a number of tools that will help you see and understand what’s happening.Leverage powerful spectrum analysisInvestigate out-of-compliance emissions with the MXE’s built-in X-Series spectrum analysis capabilities, which include a rich set of resolution and video analysis bandwidths, detectors, and marker functions. In addition, the MXE includes the X-Series PowerSuite measurements for characterization of transmitted signals.Switching between receiver and spectrum analyzer modes is greatlysimplified with the global center frequency function, which links the viewed frequencies. When analyzing an emission, any modification of its frequency will be automatically updated in the MXE’s suspect list, simplifying the final measurement process.Enhance precompliance measurementsYou can leverage the power and usability of the MXE when making precompliance measurements. The Keysight EMI measurement applications (N6141A and W6141A) put the functionality of the MXE inside any of our X-Series signalanalyzers: PXA, MXA, EXA, or CXA. The excellent sensitivity of the X-Series signal analyzers translates into highly accurate emissions measurements.For PXA, MXA or EXA:/find/N6141A For CXA:/find/W6141AStrip Chart mode provides a unique, gap-free view that is useful fortracking DUT performance as a function of turntable or antenna position.Spectrogram displays and the signal-marker capability help you understand the amplitude–and time-varying nature of emissions.RTSA lets you see and understand high-speed transient signals that aredifficult to capture.See amplitude variation vs time with Strip ChartCharacterize the variation of signal amplitude versus time using Strip Chart, a Keysight-exclusive feature which plots data for up to three detectors. All collected data isgapless, with a two-hour time record. This feature is especially useful for capturing the azimuthal emissions characteristics of a DUT when testing on a turntable.The frequency used for the Strip Chart display is coupled to the suspect list, making it easy to view each signal in the suspect list.View varying emissions with spectrograph displaysObserve how emissions spanning a broad spectral range change over time using the built-in spectrograph display. Tracking any variations in spectral data can provide clues about the origins of out-of-compliance emissions.Capture transient signals with real-time spectrum analysisDiagnose high-speed transient signals using real-time spectrum analysis (RTSA) with frequencymask trigger capability. Preselected microwave RTSA enables image-free, over-the-air signal analysis so you can more quickly and easily analyze sources of radiated emissions.Build a Complete EMI Test SolutionProtect Your Investment with an Upgradable PlatformOur qualified Keysight Solution Partners provide a single point of contact to purchase complete EMI measurement solutions that meet commercial and military specifications. In addition to the MXE EMI receiver, they can provide equipment including chambers, probes, towers and antennas, and services such as integration, installation, training, and support. To further simplify testing, they also offer automation software that can meet your specific needs.If you need to go beyond emission and immunity, our solution partners can provide ESD, line harmonics, droop testing, and more.To keep your instrument current and extend its longevity, the MXE offers easy upgradability of hardware and software. When needed, you can enhanceplatform performance through upgradable CPU, memory, disk drives, and I/O ports. Internally, the mechanical assembly has three expansion slots that can accommodate future enhancements.On the software side, simple license-key upgrades are all it takes to add functionality or measurement applications. For example, the external source control option lets the MXE interface with a variety of Keysight signalgenerators, enabling stimulus/response testing up to 20 GHz. For detailed signal analysis, the library of available measurement applications includes analog demodulation, phase noise, and noise figure.Upgrade frequencyThrough return-to-Keysight upgrades, you can extend the frequency range of MXE EMI receivers up to 44 GHz.

EM5080B 与R*品牌接收机辐射(EMI)测试曲线对比案例参考标准：GB9254:EN550323mClass B(QP)信息技术设备的无线电骚扰限值和测量方法测量设备选型：设备名称规格图片备注接收机1频率：EM5080B：9kHz-1GHz精度：≤1.5dB EM5080B 为时域接收机，扫描速度非常快，传导测量可在2.5s 内完成。

接收机2R*品牌：9KHz-3.6GHz 认证级接收机对数周期天线Schwarzberck VULB916330MHz-3GHz电波暗室3米法半电波暗室（9*6*6）概述：辐射干扰(EMI)是指干扰源通过空间把其信号耦合(干扰)到另一个电网络，能发射电磁波并影响其他系统或本系统内其他子系统的正常工作。

使用Schwarzberck对数天线检测出设置在电波屏蔽室内的试验品的辐射信号，通过EMI接收机来测量频率与强度，通过相关标准判定是否符合要求。

以下测试产品为客户的DC-DC电源，下面使用R*品牌的接收机与知用的EM5080B接收机测试。

1.概述
EM5030/EM5030LF 是两款主要用于电磁兼容整改时定位干扰源的近场探头。

EM5030的频率范围是30MHz-3GHz，EM5030LF的频率范围是1MHz-50MHz。

当产品的辐射或传导干扰超过标准时，可用近场探头来寻找产品中哪个元件或电路产生了该频率的干扰。

EM5030/EM5030LF 是一种磁场（H）探头，它有效地屏蔽了电场干扰（E），可以精确定位磁场干扰源。

当干扰信号比较弱时，可以配合本公司的EM5020A(20dB增益)或者EM5020B(30dB增益)前置放大器可
以提高系统测试灵敏度。
