In the event of conflict between the requirements of this standard and the referenced documents, this standard takes precedence.1.3.1 EIA standardsEIA-364-46: Microsecond Discontinuity Test Procedure for Electrical Connectors, Contacts and SocketsEIA-364-87: Nanosecond Event Detection for Electrical Connectors, Contacts and Sockets1.4 Definitions1.4.1 AxisThe following mounting axis definitions shall be employed during the performance of this test. Figure 1 indicates a pictorial view of the axis definitions. The referencing document shall indicate the fixturing required or the axis definitions if different than as stated in figure 1. Axis definitions for symmetrical, square and “free” connectors shall be defined in the Detail Specification.1.4.1.1 X-axisAlong the longitudinal length of the test sample1.4.1.2 Y-axisThe axis perpendicular to the longitudinal length of the sample (transverse direction).1.4.1.3 Z-axisThe axis perpendicular to the fixture seating plane attached to the test table.Figure 1 - Mounting axis definitions1.4.2 The term gnThis term is the SI unit for the standard acceleration due to the earth’s gravity, which itself varies with altitude and geographic latitude. NOTE — In this standard the value of g n is 9.81 m/s 2.2. Test resources2.1 Equipment2.1.1 The monitoring transducer shall be calibrated against a standard transducer having an accuracy of ±2%. The vibration system consisting of the vibration machine, together with its auxiliary test equipment, shall be capable of generating either a sinusoidal or random excitation.2.1.2 Test equipment for random vibration shall produce random excitation that possesses a gaussian (normal) amplitude distribution, except that the acceleration magnitudes of the peak values may be limited to a minimum of three times the rms [three-sigma (3σ) limits].3 Test specimen3.1 A vibration test sample shall be a fully wired connector consisting of one of the following, as applicable;3.1.1 A connector plug and its mating connector receptacle.3.1.2 A printed circuit connector receptacle and its mating connector board(s).3.1.3 An integral, functional connector assembly.3.2 Each test sample shall be prepared with wire and other materials or processes, simulating application assembly of the sample. If normal connector mating is dependent upon forces external to the connector, then such forces and mounting arrangement shall be as closely duplicated as possible (example: printed circuit connectors). If mating is achieved with normal locking means, then only normal locking means shall be used.3.3 Method of mounting3.3.1 Test conditions I, II, III and IV (sinusoidal evaluation conditions)The specimen shall be attached to a fixture capable of transmitting the vibration conditions specified. The test fixture shall be designed so that resonant vibration inherent in the fixture within the frequency range specified for the test shall be minor. The magnitude of the applied vibration shall be monitored on the test fixture near the specimen mounting points. The test specimen shall be mounted rigidly to the test fixture as specified and shall simulate as closely as possible the normal mounting of the specimen. A minimum of 200 mm (approx 8 in) of wire or cable shall be unsupported on both ends of the connector. For specimens with attached brackets, one of the vibration-test directions shall be parallel to the mounting surface of the bracket. Vibration input shall be monitored on the mounting fixture in the proximity of the support points of the specimen.3.3.2 Test conditions V, VI and VII (random excitation conditions)The specimen shall be mounted as specified. The orientation of the specimen or direction of application of the applied vibration motion shall be specified in one or more directions. If the order of application of the different directions is critical, it also shall be specified. Any special test fixtures or jigs required to run the test shall be specified in sufficient detail to assure reproducibility of the input motion applied to the specimen. These details shall include the dimensions, the materials, temper, etc., as applicable.4 Test procedureTests and measurements before, during and after vibration shall be as specified in the referencing document.4.1 Test conditions I, II, III and IV4.1.1 Electrical load and discontinuity4.1.1.1 Unless otherwise specified in the referencing document, an electrical load of 100 milliamperes maximum with a detector capable of detecting a discontinuity of 1.0 microsecond or longer. Said monitoring shall be performed in accordance with EIA-.364-46.4.1.1.2 Unless otherwise specified in the referencing document, low nanosecond event detection shall be performed in accordance with EIA-364-87. A 100 milliamperes test current shall be applied to the areas being monitored. A detector capable of measuring an event resulting in a 10 ohm change lasting longer than 10 nanoseconds, unless otherwise specified in the referencing document.4.1.1.2.1 Low nanosecond event detection shall not be used as a substitute for the standard 1.0 microsecond requirement. This monitoring test was developed to detect different failure mechanisms than that described in 4.1.1.1. It is designed to detect large resistance fluctuations or voltage variations that may result in improper triggering of high speed digital circuits.4.1.2 Vibration conditionsVibration conditions shall be in accordance with table 1, as applicable.Table 1 - Vibration conditionsTest conditions Frequency range, Hz Peak levelg n m/s2I Low - 10 to 55II High - 10 to 500 10 98.1III High - 10 to 2,000 15 147.1IV High - 10 to 2,000 20 196.14.1.3 ResonanceA critical resonant frequency is that frequency at which any point on the specimen is observed to have a maximum amplitude more than twice that of the support points.

This cycle shall be performed 12 times in each of three mutually perpendicular directions (total of 36 times), so that the motion shall be applied for a total period of approximately 12 hours. Interruptions are permitted provided the requirements for rate of change and test duration are met.Completion of cycling within any separate band is permissible before going to the next band. When the procedure (see 4.1.4.) of this standard is used for the 10 Hz to 55 Hz band, the duration of this portion shall be the same as the duration for this band using logarithmic cycling (approximately 1-1/3 hours in each of three mutually perpendicular directions).4.1.8 Alternative procedure for use of linear in place of logarithmic change of frequency Linear rate of change of frequency is permissible under the following conditions:4.1.8.1 The frequency range above 55 Hz shall be subdivided into no fewer than three bands. The ratio of the maximum frequency to the minimum frequency in each band shall be not less than two (2).4.1.8.2 The rate of change of frequency in Hz per minute shall be constant within any one band.4.1.8.3 The ratios of the rate of change of frequency of each band to the maximum frequency of that band shall be approximately equal.4.1.8.3.1 Example of alternative procedureAs an example of the computation of rates of change, assume that the frequency spectrum has been divided into three bands, 55 Hz to 125 Hz, 125 Hz to 500 Hz and 500 Hz to 2,000 Hz, in accordance with 4.1.8.1. For each band, let the constant, κ, represent the frequency change (in Hz/minute), divided by the maximum frequency (in Hz). Then the rates of change for the three bands will be 125κ, 500κ and 2,000κ, respectively. The times (in minutes) to traverse the three frequency bands are1255512550012550020005002000−−−κκκ,,,andSince the minimum total sweep time is 30 minutes,701253755001500200030κκκ++=,,whence κ = 0.0687/minute.The required maximum constant rates of frequency change for the three bands are therefore 8.55 Hz per minute, 34.2 Hz per minute and 137 Hz per minute, respectively. The minimum times of traverse of the bands are 8.2 min, 10.9 min and 10.9 min, respectively.4.2 Test conditions V, VI and VII4.2.1 Control and analysis of random vibration4.2.1.1 Spectral density curvesThe output of the vibration machine shall be presented graphically as power-spectral density versus frequency; see 4.2.1.1.1. The spectral-density values shall be within +40% and -30% (±1.5 dB) of the specified values between a lower-specified frequency and 1,000 Hz, and within +100% and -50% (±3 dB) of the specified values between 1,000 and an upper-specified frequency (2,000 Hz). A filter bandwidth will be a maximum of 1/3-octave or a frequency of 25 Hz, whichever is greater.4.2.1.1.1 Power-spectral densityPower-spectral density is the mean-square value of an oscillation passed by a narrow-band filter per unit-filter bandwidth. For this application it is expressed as g 2 / f, where g 2 / f is the mean-square value of acceleration expressed in gravitational units per number of cycles of filter bandwidth. The spectral density curves are usually plotted either on a logarithmic scale, or in units of decibels (dB). The number of decibels is defined by the equation:The rms value of acceleration within a frequency band between f 1 and f 2 is:g = f df rms 2f f 12g ∫//12where g r 2 / f is a given reference value of power-spectral density, usually the maximum specified value.4.2.1.2 Distribution curvesA probability density-distribution curve may be obtained and compared with a gaussian-distribution curve. The experimentally-obtained curve shall not differ from the gaussian curve by more than ± 10% of the maximum value.4.2.1.3 MonitoringMonitoring involves measurements of the vibration excitation and of the test item performance. When required in the referencing document, the specimen may be monitored during the test. The details of the monitoring circuit, including the method and points of connection to the specimen, shall be specified.dB = 10 g /f g /f = 20 g /fg /f2r r log log 24.2.1.4 Vibration inputThe vibration magnitude shall be monitored on a vibration machine, on mounting fixtures, at locations that are as near as practicable to the test item mounting points. When the vibration input is measured at more than one point, the minimum input vibration shall normally be made to correspond to the specified test curve; see figures 4 and 5. For massive test items and fixtures, and for large force exciters or multiple vibration exciters, the input control value may be an average of the average magnitudes of three or more inputs. Accelerations in the transverse direction, measured at the test item attachment points, shall be limited to 100% of the applied vibration. The number and location of the test points shall be specified.4.2.2 ProcedureThe specimen, or substitute equivalent mass, shall be mounted in accordance with 3.3.2 and the monitoring equipment attached, if applicable, in accordance with 4.2.1.3. The vibration machine shall then be operated and equalized or compensated to deliver the required frequencies and intensities conforming to the curves specified in test condition V, figure 4, or test condition VI, figure 5, or test condition VII, figure 6 (see 2.1). The specimen shall then be subjected to the vibration specified by the test condition letter (see tables 2, 3 and 4) for the duration as specified:3 minutes; 15 minutes; 1-1/2 hours; or 8 hours;in each of three mutually perpendicular directions, and in the order specified (see 3.3.2), as applicable.The measurements made before, during, and after the test shall be specified and if the specimen is to be monitored during the test, the details shall be in accordance with 4.2.1.3.4.2.3 Electrical load and discontinuities4.2.3.1 Unless otherwise specified in the referencing document, an electrical load of 100 milliamperes maximum with a detector capable of detecting a discontinuity of 1.0 microsecond or longer. Said monitoring shall be performed in accordance with EIA-.364-46.4.2.3.2 Unless otherwise specified in the referencing document, low nanosecond event detection shall be performed in accordance with EIA-364-87. A 100 milliamperes test current shall be applied to the areas being monitored. A detector capable of measuring an event resulting in a 10 ohm change lasting longer than 10 nanoseconds, unless otherwise specified in the referencing document.4.2.3.2.1 Low nanosecond event detection shall not be used as a substitute for the standard 1.0 microsecond requirement. This monitoring test was developed to detect different failure mechanisms than that described in 4.2.3.1. It is designed to detect large resistance fluctuations or voltage variations that may result in improper triggering of high speed digital circuits.Figure 4 - Test condition V, random vibration test-curve envelope (see table 2).Table 2 - Values for test condition V 1)Test condition letter Power spectral density, g 2/Hz Overall rms gA 0.02 5.35B 0.04 7.56C 0.06 9.26D 0.1 11.95E 0.2 16.91F 0.3 20.71G 0.4 23.91H 0.6 29.28I Superseded by Test condition letterJ J 1.0 37.80K 1.5 46.301) For duration of test; see 4.2.2.Figure 5 - Test condition VI, random vibration test-curve envelope (see table 3).Table 3 - Values for test-condition VI 1)Test condition letter Power spectral density, g 2/Hz Overall rms gA 0.02 6.21B 0.04 8.78C 0.06 10.76D 0.1 13.89E 0.2 19.64F 0.3 24.06G 0.4 27.78H 0.6 34.02I Superseded by Test condition letterJ J 1.0 43.92K 1.5 53.791) For duration of test; see 4.2.2.Figure 6 - Test condition VII, random vibration test-curve envelope (see table 4)Table 4 - Values for test condition VII 1)Test condition letter Power spectraldensity, g 2/Hz Overall rms gA 0.002 0.98B 0.005 1.55C 0.01 2.19D 0.02 3.10E 0.05 4.90F 0.1 6.93G 0.29.801) For duration of test; see 4.2.2.5 Details to be specifiedThe following details shall be specified in the referencing document:5.1 Type of sample; see 3.15.2 Number of samples to be tested5.3 Method of mounting; see 3.35.4 Test condition number; see tables 1, 2, 3 or 45.5 Electrical load conditions, all contacts, if other than 100 milliamperes maximum; see 4.1.1 or 4.2.35.6 Discontinuity requirement if other than 1 microsecond5.7 Measurement of discontinuities during vibration; see 4.1.1 or 4.2.35.8 Method of determining resonance, if applicable; see 4.1.35.9 Direction of motion and order, if critical; see 3.35.10 Tests or measurements before, during and after vibration; see clause 45.11 Duration of vibration; see 4.1.4 or 4.2.25.12 Monitoring instrumentation, if applicable; see 4.2.1.35.13 Number and location of test points, if applicable; see 4.2.1.35.14 Mounting axes definitions if other than indicated in figure 1; see 1.46 Test documentationDocumentation shall contain the details specified in clause 5, with any exceptions, and the following:6.1 Title of test6.2 Sample description include fixture, if applicable6.3 Test equipment used, and date of last and next calibration6.4 Photographs, plots, values and observations necessary for proof of conformance6.5 Name of operator and start/finish date(s) of testRevision HistoryRevision letter ProjectnumberAdditions, changes and deletionsE SP-5125 Changed test condition letter I to J.

EIA-364-90 串音 (Crosstalk) 测试1.简介1.1范围这个测试程序应用于连接系统,比如像电子连接器,插座,和缆线组件整合.1.2目的这个标准描述了如何量测在连接系统整合中驱动线路和承受线路电磁耦合的量.时域(方法A)和频域(方法B)的量测方法,单动和差动的传输,还有插入式和参考治具测量法都将会叙述.1.3定义1.3.1 驱动讯号对于时域的测量来说,驱动讯号为一步阶波形;对于频域的测量,驱动讯号为一弦波波形.1.3.2 串音比串音比的定义为耦合到承受线路导体或导体对的讯号量比上在驱动线路导体或导体对上的讯号量.不管是耦合或驱动的讯号必须用相同的单位,比如说电压或电流,而串音比必须用百分比或 dB来表示.1.3.3 近端串音比(Near End Crosstalk Ratio – NEXT)串音比是由承受线路在接近驱动线路的发送端而量得,这个串音比是由近端的承受线路讯号量比上近端的驱动线路讯号量.1.3.4 远程串音比(Far End Crosstalk Ratio – FEXT)串音比是由承受线路在接近驱动线路的接收端而量得,这个串音比是由远程的承受线路讯号量比上近端的驱动线路讯号量.1.3.5 量测系统爬升时间量测系统爬升时间为包含治具,经过滤波效应(filtering),但不包含待测物,所测得的爬升时间.爬升时间通常是量测从 10%到90%的位准所需花费的时间.1.3.6 待测环境阻抗阻抗是由治具上的传导讯号导体所呈现.阻抗是由传输线,终端电阻,接收端,讯号来源和治具寄生效应的结果.1.3.7 步阶振幅如图一所示,步阶振幅是从 0% 到 100% ,忽略 overshoot 和 undershoot, 的电压差值.1.3.8 隔离标准板(Isolation Standard)隔离标准板为一没有待测物,但与测试治具有相同的串音特性的参考治具,这个治具可以为或可以不为测试板的一部份.1.3.9 终端连接在传输线末端的阻抗,通常是为了减小在传输在线的反射能量.2.测试资源2.1设备2.1.1 方法 A,时域2.1.1.1步阶讯号产生器连接于驱动线路,而承受线路则连接于示波器.如果是差动讯号的应用,则步阶讯号产生器和示波器都必须要有处理差动讯号的能力,这表示输出端要能调整振幅和 skew的差异,而输入端要能显示两个输入讯号的差跟和,为了能更改不同的爬升时间,仪器要提供滤波(filtering)或归一化(normalization)的功能.在这种情况下,时域反射仪(TDR)通常会被采用.2.1.1.2 探针当探针被采用的时候,必须要有合适的爬升时间表现和负载电路特性.2.1.2 方法B,频域网络分析仪(Network Analyzer)是较为偏好的,当需要较大的动态范围(dynamic range)时,讯号产生器和频谱分析仪的组合也可为替代的方案.一个八端口的网络分析仪或baluns可用来做差动讯号的测量.2.2治具除非在参考文件中有其他特别规定,否则待测物环境阻抗必须要匹配测试设备的阻抗.通常单动 (single-ended) 量测要求 50奥姆的阻抗而差动(differential) 量测要求 100奥姆.2.2.1 待测物导体配置对于每一个测量,驱动线路和承受线路必须如参考文件所示而摆置,如果可能的话,邻近于待测线路的线路必须做终端(terminated)的动作.除非有其他特别的规定,否则采用 1:1的讯号对接地的比例(如果是做差动讯号的测量,则采用一对差动讯号线路对应一个接地线路),所有的线路都对应到相同的接地面,如图二所示.治具必须设计成所有的线路有相同的时间延迟.注意–当驱动讯号为差动的模式且非均衡时,则共模(common mode)讯号的能量必须被终端(terminated)图二2.2.2 终端驱动线路的远程和承受线路的两边末端都必须用待测环境阻抗做终端,所采用的方法可以参考图三或图四,如果待测环境阻抗和测量设备的阻抗不匹配的话,可使用匹配电路(matching network),在整个的频率量测范围内必须注意到尽量减小电阻性终端的电抗效应.注意–治具的几何形状和材质会影响到测量肇因于治具的寄生效应,所以通常以产品的用途来规划最有意义的治具形态.图三单动模式测量的阻抗终端图四差动模式测量的阻抗终端2.2.3 串音从待测物所量得的串音中分离出治具的串音是困难的,所以参考文件必须规范治具以使治具所产生的串音量减到最小.注意–因为测试板的脚位布局或缆线组件整合的终端技术会严重地影响到串音量,所以建议治具应包含隔离标准板(Isolation Standard)2.2.4 插入式技术治具(Insertion Technique Fixture)这种治具必须设计成不管有没有加入待测物都可以做串音的测量,如图五所示,如果为了双动测量(balanced measurement)而使用baluns,或为了阻抗匹配而使用最小损耗垫(minimum loss pads),如图三和图四所示,这些都包含在治具2.2.5 参考治具技术(Reference Fixture Technique)使用这种技术一个个别包含有近端和远程的治具将会被用来做治具串音的测量,这个治具,除了没有待测物外,将是待测物治具的复制品;如果有电路线路的话,必须包含治具的连接器,贯孔,弯折(bends),和转角(corners);如果为了双动测量(balanced measurement)而使用baluns,或为了阻抗匹配而使用最小损耗垫(minimum loss pads),如图三和图四所示,这些都包含在治具之中.之中.3.待测物3.1叙述这项测试的待测物必须有一条以上的讯号线,而且必须为下列对象之一:一.1.1可分离的连接器接合一起的连接器配对.一.1.2缆线整合组件附有连接器或接合在一起的连接器配对的缆线.一.1.3插座插座和测试组件,或插座和可插入的转接头.一. 4.测试步骤一.驱动线路的远程和承受线路的两端都必须用待测环境阻抗做终端,终端的方法可用图三和图四的其中一种.一.4.1方法A,时域一.4.1.1一般性原则一.4.1.1.1待测物必须放置距离会影响测量结果之对象至少 5cm 远之处.一.4.1.1.2 参考测量和治具串音一.4.1.1.2.1量测并纪录从10%到90%位准的量测系统爬升时间,除非参考文件有其他任何的规范.一.4.1.1.2.2治具的串音会添加在待测物的串音中,如果有使用最小损耗垫,那么最小损耗垫也包含在治具之中;如果参考文件明确地描述治具,那么治具所贡献的串音量即为已知值,则治具串音的测量就是非必须的;这些结果是量测量对时间的关系图,用以下的其中一种技术来量测量测系统爬升时间,驱动线路振幅,和治具串音量.一.4.1.2插入式测量法一.4.1.2.1在不加入待测物的情况下,把治具的近端和远程连接起来,将示波器和脉冲讯号产生器连接在驱动线路治具的适当位置;对多个同步驱动讯号线路,匹配它们的振幅,并且减小它们之间的 skew;对双动讯号的测量,减小这对线路的skew,量测并报告 skew的值.一.4.1.2.2如果同步要被驱动的线路数目超过了设备的容许值,或者频道间 skew的排除是一件令人担心的事,那么一次驱动一条线路且串音量以迭加(superposition)的方式纪录下来.一.4.1.2.3量测驱动讯号在通过治具时的步阶爬升时间和振幅(如果有要求,这个动作可以使用加上待测物的治具来完成),调整滤波功能使得量测爬升时间符合要求的值,或如表一的值.表一4.1.2.4依照参考文件将示波器连接于承受线路,测量将待测物移除的治具串音量,将治具串音振幅除以步阶讯号振幅以求得治具串音比并将其表示成百分比的形式,除非有其他的规范,否则将峰值和符号给纪录下来.4.1.3 参考治具测量法4.1.3.1将示波器和脉冲产生器连接在驱动线路的适当位置;对于双动讯号的测量,讯号源必须使正向和负向的步阶讯号振幅一致,且将其 skew移除;对于多个同步驱动讯号线路,使其振幅一致且移除 skew.4.1.3.2如果同步要被驱动的线路数目超过了设备的容许值,或者频道间 skew的排除是一件令人担心的事,那么一次驱动一条线路且串音量以迭加(superposition)的方式纪录下来.4.1.3.3量测驱动讯号在通过参考治具时的步阶爬升时间和振幅(如果对远程串音有要求,这个动作可以使用加上待测物的治具来完成),调整滤波功能使得量测爬升时间符合要求的值,或如表一的值.4.1.3.4如参考文件所示,将示波器连接在参考治具的承受线路上,量测承受线路接收到的最大振幅,把这个值减去在驱动讯号产生前承受线路上的讯号振幅以便获得承受线路的串音量(包含符号),将承受线路的串音量除以步阶讯号的振幅以计算治具串音比,并将其表示成百分比的形式.4.1.4 待测物串音测量4.1.4.1在治具上加入待测物.4.1.4.2将示波器连接在承受线路被要求的位置,而同样的,把步阶讯号产生器连接在驱动讯号线路被要求的位置;对于双动讯号的测量,讯号源必须使正向和负向的步阶讯号振幅一致,且将其 skew移除;对于多个同步驱动讯号线路,使其振幅一致且移除 skew.4.1.4.3如果同步要被驱动的线路数目超过了设备的容许值,或者频道间 skew的排除是一件令人担心的事,那么一次驱动一条线路且串音量以迭加(superposition)的方式纪录下来.4.1.4.4量测承受线路接收到的最大振幅,把这个值减去在驱动讯号产生前承受线路上的讯号振幅以便获得承受线路的串音量(包含符号),将待测物-与-治具的承受线路的串音量除以步阶讯号的振幅以计算待测物-与-治具的串音比,并将其表示成百分比的形式.注意-当治具的串音量接近于待测物-与-治具的串音量时,对于结果的解释就要小心了,从这项测试减去治具串音并不是正确的做法.。
