limits are formulated only in restricted frequency bands, which is considered sufficient to reach adequate emission levels to protect radio broadcast and telecommunication services, and to allow other apparatus to operate as intended at reasonable distance.– 7 – EN 55022:2006 INFORMATION TECHNOLOGY EQUIPMENT –RADIO DISTURBANCE CHARACTERISTICS –LIMITS AND METHODS OF MEASUREMENT1 Scope and objectThis International Standard applies to ITE as defined in 3.1.Procedures are given for the measurement of the levels of spurious signals generated by the ITE and limits are specified for the frequency range 9 kHz to 400 GHz for both class A and class B equipment. No measurements need be performed at frequencies where no limits are specified.The intention of this publication is to establish uniform requirements for the radio disturbance level of the equipment contained in the scope, to fix limits of disturbance, to describe methods of measurement and to standardize operating conditions and interpretation of results.2 Normative referencesThe following referenced documents are indispensable for the application of this document.

The TCM wave is the transmission mode of electrical energy, which can lead to radiation of electrical energy if the cable is exposed in the real application. Vice versa, this is also the dominant mode, which results from exposition of the cable to external electromagnetic fields.3.9arrangementphysical layout of the EUT that includes connected peripherals/associated equipment within the test area3.10configurationmode of operation and other operational conditions of the EUT3.11associated equipmentAEequipment needed to maintain the data traffic on the cable attached to the EUT port under test and (or) to maintain the normal operation of the EUT during the test. The associated equipment may be physically located outside the test areaNOTE The AE can be another ITE, a traffic simulator or a connection to a network. The AE can be situated close to the measurement set-up, outside the measurement room or be represented by the connection to a network. AE should not have any appreciable influence on the test results.4 Classification of ITE4.1 Class B ITEClass B ITE is a category of apparatus which satisfies the class B ITE disturbance limits. ITE is subdivided into two categories denoted class A ITE and class B ITE.EN 55022:2006 – 10 – Class B ITE is intended primarily for use in the domestic environment and may include:– equipment with no fixed place of use; for example, portable equipment powered by built-inbatteries;– telecommunication terminal equipment powered by a telecommunication network; – personal computers and auxiliary connected equipment.NOTE The domestic environment is an environment where the use of broadcast radio and television receivers may be expected within a distance of 10 m of the apparatus concerned.4.2 Class A ITE WarningThis is a class A product. In a domestic environment this product may cause radio inter-ference in which case the user may be required to take adequate measures.5 Limits for conducted disturbance at mains terminalsand telecommunication portsThe equipment under test (EUT) shall meet the limits in Tables 1 and 3 or 2 and 4, as appli-cable, including the average limit and the quasi-peak limit when using, respectively, an average detector receiver and quasi-peak detector receiver and measured in accordance with the methods described in Clause 9. Either the voltage limits or the current limits in Table 3 or 4, as applicable, shall be met except for the measurement method of C.1.3 where both limits shall be met. If the average limit is met when using a quasi-peak detector receiver, the EUT shall be deemed to meet both limits and measurement with the average detector receiver is unnecessary.If the reading of the measuring receiver shows fluctuations close to the limit, the reading shall be observed for at least 15 s at each measurement frequency; the higher reading shall be recorded with the exception of any brief isolated high reading which shall be ignored.5.1 Limits of mains terminal disturbance voltageTable 1 – Limits for conducted disturbance at the mains portsof class A ITE Limits dB(μV) Frequency rangeMHzQuasi-peak Average 0,15 to 0,5079 66 0,50 to 30 73 60NOTE The lower limit shall apply at the transition frequency.Class A ITE is a category of all other ITE which satisfies the class A ITE limits but not the class B ITE limits.

It is also recom-mended that international organizations use these limits.7.1.2The significance of the limits for equipment shall be that, on a statistical basis, at least 80 % of the mass-produced equipment complies with the limits with at least 80 % confidence.7.2 Application of limits in tests for conformity of equipment in series production7.2.1Tests shall be made:7.2.1.1Either on a sample of equipment of the type using the statistical method of evaluation set out in 7.2.3.7.2.1.2Or, for simplicity's sake, on one equipment only.7.2.2Subsequent tests are necessary from time to time on equipment taken at random from production, especially in the case referred to in 7.2.1.2.7.2.3Statistically assessed compliance with limits shall be made as follows:This test shall be performed on a sample of not less than five and not more than 12 items of the type. If, in exceptional circumstances, five items are not available, a sample of four or three shall be used. Compliance is judged from the following relationship:x kS +≤n L wherex is the arithmetic mean of the measured value of n items in the sample()S n x x n 2n 211=−−∑x n is the value of the individual itemL is the appropriate limitk is the factor derived from tables of the non-central t -distribution which assures with 80 %confidence that 80 % of the type is below the limit; the value of k depends on the sample size n and is stated below.The quantities x n , x , S n and L are expressed logarithmically: dB(μV), dB(μV/m) or dB(pW). n3 4 5 6 7 8 9 10 11 12 k 2,04 1,69 1,52 1,42 1,35 1,30 1,27 1,24 1,21 1,207.2.4 The banning of sales, or the withdrawal of a type approval, as a result of a dispute shall be considered only after tests have been carried out using the statistical method of evaluation in accordance with 7.2.1.1.8 General measurement conditions8.1 Ambient noiseA test site shall permit disturbances from the EUT to be distinguished from ambient noise. The suitability of the site in this respect can be determined by measuring the ambient noise levels with the EUT inoperative and ensuring that the noise level is at least 6 dB below the limits specified in Clauses 5 and 6.If at certain frequency bands the ambient noise is not 6 dB below the specified limit, the methods shown in 10.5 may be used to show compliance of the EUT to the specified limits. It is not necessary that the ambient noise level be 6 dB below the specified limit where both ambient noise and source disturbance combined do not exceed the specified limit. In this case the source emanation is considered to satisfy the specified limit. Where the combined ambient noise and source disturbance exceed the specified limit, the EUT shall not be judged to fail the specified limit unless it is demonstrated that, at any measurement frequency for which the limit is exceeded, two conditions are met:a) the ambient noise level is at least 6 dB below the source disturbance plus ambient noiselevel;b) the ambient noise level is at least 4,8 dB below the specified limit.。

To complete the AC front end configuration, the user only needs to add hold-up capacitors,a simple EMI filter, and a few discrete components (Fig 1A).Functional Description (F ARM3, see Figures 9 & 10)Power-Up Sequence.Upon application of input power, the hold-up capacitorsbegin to charge. The thermistor limits the charge current,and the exponential time constant is determined by the hold-up capacitor value and the thermistor cold resistance.The slope (dv/dt) of the capacitor voltage versus time approaches zero as the capacitors become charged to the peak of the AC line voltage.The switch that bypasses the inrush limiting PTC (positive temperature coefficient) thermistor is open when power is applied, as is the switch that engages the strap for voltage doubling. In addition, the converter modules are disabled via the Enable (EN) line, and Bus-OK (BOK) is high.If the bus voltage is less than 200V as the slope nearszero, the voltage doubler is activated, and the bus voltage climbs exponentially to twice the peak line voltage. If the bus voltage is greater than 200V , the doubler is not activated.If the bus voltage is greater than 235V as the slopeapproaches zero, the inrush limiting thermistor is bypassed. Below 235V , it is not bypassed.The converters are enabled 50 milliseconds after thethermistor bypass switch is closed.Bus-OK is asserted after an additional 50 milliseconddelay to allow the converter outputs to settle within specification.Power-Down Sequence.When input power is turned off or fails, the following sequence occurs as the bus voltage decays:Bus-OK is deasserted when the bus voltage falls below210Vdc.The converters are disabled when the bus voltage fallsbelow 190Vdc. If power is reapplied after the converters are disabled, the entire power-up sequence is repeated. If a momentary power interruption occurs and power is reestablished before the bus reaches the disable threshold, the power-up sequence is not repeated, i.e., the power conversion system “rides through” the momentary interruption.Application NoteFigure 9—Functional block diagram: FARM3 module Figure 10—Timing diagram: power-up/down sequence1.12.13.14.15.11.22.2Off-Line Power Supply ConfigurationThe ENMods system maintains the DC output bus voltage between 250 and 370Vdc over the entire input voltage range, which is compatible with all Vicor 300V input converters. Autoranging automatically switches to the proper bridge or doubler mode at startup depending on the input voltage, eliminating the possibility of damage due to improper line connection. The ENMods system is rated at 575W output power. These modules can serve as the AC front end for any number and combination of compatible converters as long as the maximum power rating is not exceeded.Pin Descriptions (see Figure 1a)Strap (ST) Pin.In addition to input and output power pin connections, it is necessary to connect the Strap pin to the center junction of the series hold-up capacitors (C1, C2)for proper (autoranging) operation. Varistors V1 and V2 provide capacitor protection. The bleeder resistors (R1, R2)discharge the hold-up capacitors when power is switched off. Capacitors C7 and C8 are recommended if the hold-up capacitors are located more than 3 inches from the output pins.Enable (EN) Pin.The Enable pin must be connected to the PC or Gate-In pin of all converter modules to disable the converters during power-up. Otherwise, the converters would attempt to start while the hold-up capacitors are being charged through the current limiting thermistor,preventing the bus voltage from reaching the thermistor bypass threshold, thus disabling the power supply. The Enable output (the drain of an N channel MOSFET) is internally pulled up to 15V through a 150k?resistor. (see Figure 11)A signal diode should be placed close to and in series with the PC or (Gate-In) pin of each converter to eliminate the possibility of control interference between converters.The Enable pin switches to the high state (15V) with respectto the SR pin to turn on the converters after the power-up inrush is over. The Enable function also provides input overvoltage protection for the converters by turning off the converters if the DC bus voltage exceeds 400Vdc. The thermistor bypass switch opens if this condition occurs, placing the thermistor in series with the input voltage, which reduces the bus voltage to a safe level while limiting input current in case the varistors conduct. The thermistor bypass switch also opens if a fault or overload reduces the bus voltage to less than 180Vdc. (see Figure 9)Bus-OK (BOK) Pin.(see Figure 12)The Bus-OK pin is intended to provide early-warning power fail information and is also referenced to the SR pin.Caution: There is no input to output isolation in the ENMods.It is necessary to monitor Bus-OK via an optoisolator if it is to beused on the secondary (output) side of the converters. A line isolation transformer should be used when performing scope measurements. Scope probes should never be applied simultaneously to the input and output as this will destroy the unit.L, N Pins.Line and neutral input.+, – Pins. Positive and negative outputs.SR Pin. Signal return for BOK and EN outputsFilter(see Figure 1b)The input EMI filter consists of differential and common mode chokes,Y– rated capacitors (line-ground) and X– rated capacitors (line-line). This filter configuration provides sufficient common mode and differential mode insertion loss in the frequency range between 100kHz and 30MHz to comply with the Level B conducted emissions limit, as illustrated in Figures 8a thru 8c.Hold-up CapacitorsHold-up capacitor values should be determined according to output bus voltage ripple, power fail hold-up time, and ride-through time (see Figure 13). Many applications require the power supply to maintain output regulation during a momentary power failure of specified duration, i.e., the converters must hold-up or ride through such an event while maintaining undisturbed output voltage regulation. Similarly, many of these same systems require notification of an impending power failure in order to allow time to perform an orderly shutdown.The energy stored on a capacitor which has been charged to voltage V is:ε= 1/2(CV2) (1) Where:ε= stored energyC = capacitanceV = voltage across the capacitorEnergy is given up by the capacitors as they are discharged by the converters. The energy expended (the power-time product) is:ε= P?t = C(V12–V22) / 2 (2) Where: P = operating powert = discharge intervalV1= capacitor voltage at the beginning of ?tV2= capacitor voltage at the end of ?t Rearranging Equation 2 to solve for the required capacitance:C = 2P?t / (V12–V22) (3)Figure 16—Ripple voltage vs. operating power and bus capacitance, series combination of C1, C2 (see Figure 1a)Figure 15—Ride-through time vs. operating powerFigure 13—Hold-up timeFigure 12—Bus OK (BOK) isolated power status indicatorFigure 11—Enable (EN) functionCalculated values of bus capacitance for various hold-up time,ride-through time, and ripple voltage requirements are given as a function of operating power level in Figures 14, 15, and 16, respectively.ExampleIn this example, the output required from the DC-DC converter at the point of load is 12Vdc at 320W. Therefore, the output power from the ENMods would be 375W (assuming a converter efficiency of 85%). The desired hold-up time is 9ms over an input range of 90 to 264Vac.Determining Required Capacitance for Power Fail Warning.Figure 14 is used to determine capacitance for a given power fail warning time and power level, and shows that the total bus capacitance should be at least 820µF. Since two capacitors are used in series, each capacitor should be at least 1,640µF. Note that warning time is not dependent on line voltage. A hold-up capacitor calculator is available on the Vicor website, at /doc/115727505.html.Determining Ride-through Time.Figure 15 illustrates ride-through time as a function of line voltage and output power,and shows that at a nominal line of 90Vac, ride-through would be 68ms. Ride-through time is a function of linevoltage.Determining Ripple Voltage on the Hold-up Capacitors.Figure 16 is used to determine ripple voltage as a function of operating power and bus capacitance, and shows that the ripple voltage across the hold-up capacitors will be 12V p-p.Determining the Ripple on the Output of theDC-DC Converter.Figure 17 is used to determine the ripple rejection of the DC-DC converter and indicates a ripplerejection of approximately 60 dB for a 12V output. Since the ripple on the bus voltage is 12Vac and the ripple rejection of the converter is 60 dB, the output ripple of the converter due to ripple on its input (primarily 120 Hz) will be 12mV p-p. Note that 2nd Generation converters have greater ripple rejection then either VI-200s or VI-J00s.A variety of hold-up capacitor assemblies (HUBs) areavailable. Please visit the Vicor website @ /doc/115727505.html.For more information about designing an autorangingAC input power supply using the ENMods and Vicor DC-DC converter modules, contact Vicor Applications Engineering at the nearest Vicor Technical Support Center, or send E-mail to apps@/doc/115727505.html.The power fail warning time (?t) is defined as the interval between BOK and converter shutdown (EN) as illustrated in Figure 13. The Bus-OK and Enable thresholds are 205V and 185V, respectively. A simplified relationship between hold-up time, operating power, and bus capacitance is obtained by inserting these constants in equation (3):C = 2P ?t / (2052– 1852)C = 2P ?t / (7,800)It should be noted that the series combination (C1, C2, see Figure 1a)requires each capacitor to be twice the calculated value, but the required voltage rating of each capacitor is reduced to 200V.Allowable ripple voltage on the bus (or ripple current in the capacitors) may define the capacitance requirement. Consideration should be given to converter ripple rejection and resulting output ripple voltage. The ripple rejection (R) of Vicor converters is specified as a function of the input/output voltage ratio:R = 30 + 20log(Vin / Vout)(4)For example, a converter whose output is 15V and nominal input is 300V will provide 56dB ripple rejection, i.e., 10V p-p of input ripple will produce 15mV p-p of output ripple (see Figure 17). Equation 3 is again used to determine the required capacitance. In this case, V 1and V 2are theinstantaneous values of bus voltage at the peaks and valleys (see Figure 13)of the ripple, respectively. The capacitors must holdup the bus voltage for the time interval (?t) between peaks of the rectified line as given by:t = (π– θ) / 2πf(5)Where:f = line frequencyθ= rectifier conduction angleThe approximate conduction angle is given by:θ= Cos -1(V 2/V 1)(6)Another consideration in hold-up capacitor selection is their ripple current rating. The capacitors’ rating must be higher than the maximum operating ripple current. The approximate operating ripple current (rms) is given by:I rms = 2P/V ac (7)Where: P = total output powerV ac = operating line voltageMechanical DiagramINBOARDSOLDER ONBOARD SOLDER ALUMINUM BASEPLA TEVicor’s comprehensive line of power solutions includes modular, high density DC-DC converters and accessory components, configurable power supplies, and custom power systems.Information furnished by Vicor is believed to be accurate and reliable.

Interpretation:1. Selection of Average detectorCISPR 22 defines limits for radiated emissions at frequencies between 1 GHz and 6 GHz with respect to both average and peak detectors. CISPR 16-1-1 defines two types of Average detector for use above 1 GHz. For the limits given in CISPR 22 the appropriate average detector is the linear average detector defined in 6.4.1 of CISPR 16-1-1:2006 with its Amendments 1:2006 and 2:2007.BS EN 55022:2010--``,```,`,`,`,`,,````,,,,,```,,-`-`,,`,,`,`,,`---2. Measurement of conducted emissions on cabinets containing multiple items of equipmentWhere the EUT is a cabinet or rack that contains multiple items of equipment that are powered from an AC power distribution strip and where the AC power distribution strip is an integral part of the EUT as declared by the manufacturer, the AC power line conducted emissions should be measured on the input cable of power distribution strip that leaves the cabinet or rack, not the power cables from the individual items of equipment.

As a result the work identified within CISPR/I/279/MCR will not be started for the time being. At the subsequent meeting of CISPR SC I WG3 it was decided that 3 items within the MCR would benefit now from further clarification and an interpretation sheet would be helpful to users of the standard, with the intent of including this information in a future amendment to the standard.The first draft of an interpretation sheet CISPR/I/290/DC addressed the 3 items, however it was clear from the comments received (CISPR/I/293A/INF) that further work was required on the 3rd item related to ISN selection, and it was decided that this would be the subject of a separate document.This information does not change the standard; it serves only to clarify the points noted. CISPR SC I WG3 hopes that these clarifications will be of use to users and especially laboratories testing to CISPR 22:2008 (Edition 6.0).Selection of ISN for unscreened balanced multi-pair cablesSubclause 9.6.3.1 of CISPR 22 states that:“When disturbance voltage measurements are performed on a single unscreened balanced pair, an adequate ISN for two wires shall be used; when performed on unscreened cables containing two balanced pairs, an adequate ISN for four wires shall be used; when performed on unscreened cables containing four balanced pairs, an adequate ISN for eight wires shall be used (see Annex D)”Therefore the selection of ISN is based on the number of pairs physically in the cable, not the number of pairs actually used by the interface in question.--``,```,`,`,`,`,,````,,,,,```,,-`-`,,`,,`,`,,`---– 2 –However, selection of a suitable ISN design from the examples given in Annex D requires further consideration. The ISN designs given in Figures D.4 to D.7 are only appropriate for use where all of the balanced pairs in the cable are ‘active’ and hence their use requires a more detailed knowledge of the EUT port being tested. The ISN designs given in Figures D.1 to D.3 have no such limitation and are better suited to applications where the actual use of the pairs is unknown.The ISN designs given in Figures D.2 and D.3 are also suitable for measurements on unscreened cables containing fewer balanced pairs than the maximum number of pairs the ISN is designed for (see example 2).The following definitions have been developed to help in determining what should be considered an ‘active’ pair of conductors:An active pair is a pair of conductors that completes an active digital, analogue, or power circuit, or is terminated in a defined impedance, or is connected to earth or the equipment frame/chassis.NOTE These circuits include such applications as "Power over Ethernet".A circuit is an a ctive circuit when it is in a state that is performing its intended function, which may include communications, voltage/current sensing, impedance matching or power supply.NOTE A conductor with no intended function is not part of an active circuit.A measurement using an ISN described in Figures D.4 to D.7, when not all of the pairs are ‘active’, may result in a significant error in the measured emissions. It is therefore important that test laboratories determine on which of the designs given in the annexes their particular ISNs are based. From this they can then determine if they need to establish the number of ‘active’ pairs within the cable or not and then whether their ISNs are suitable for the port being measured or whether an alternative measurement technique needs to be used. This is applicable when measuring in accordance with 9.6.3.1 or 9.6.3.2. It is recommended that test reports should make reference to:• the ISN category used;• the Annex D figure corresponding to their particular ISN design;• the total number of pairs in the cable and number of these that where active. Example 1:The EUT has an Ethernet port to which either a CAT 5 or 6 cable is connected. Typically these cables have four pairs requiring use of a four pair ISN. Transmission using 1000Base-T Ethernet protocol uses all four pairs of a typical cable. Transmission using 10Base-T and 100 Base-T Ethernet protocol uses only two of the four pairs for communication. One of the following ISNs could therefore be used:1) ISN as shown in Figure D.3, or2) ISN as shown in Figures D.6 or D.7 if it is known that all the pairs within the cable are‘active’. This would be the case if a 1000BaseT Ethernet protocol were being used. These ISNs would also be suitable for 10BaseT or 100BaseT protocol if the unused pairs have controlled terminations in the EUT port by design, making all pairs ‘active’ from an EMC perspective. Should an EUT with an Ethernet port be provided with a cable that contains only 2 pairs within it, then any of the following types of ISN could be used: D2, D3, D4 or D5.BS EN 55022:2010--``,```,`,`,`,`,,````,,,,,```,,-`-`,,`,,`,`,,`---– 3 –Example 2:The EUT has a single ADSL port and is provided with a cable containing 2 pairs. ADSL is a single pair system so only 1 pair is active. The following ISNs could be used:1) ISN as shown in Figure D.2 or D.3.Cable length between ISN and EUT when measuring telecommunication portsSubclause 9.5.1 of CISPR 22 requires that the distance between the ISN and the EUT be nominally 0.8m and also clause 9.5.2 states that:“Signal cables shall be positioned for their entire lengths, as far as possible, at a nominal distance of 0,4 m from the ground reference plane (using a non-conductive fixture, if necessary).”No other requirement is given on the actual length of the cable to be used.Measurements have shown that non-inductive bundling of any excess cable can result in slightly higher emission levels measured at the ISN.It is therefore recommended that the cable between the telecommunication port and the ISN should be kept as short as possible, in order to avoid the need to bundle any excess, while maintaining the requirements given in 9.5.1 and 9.5.2.BS EN

欧盟EN55022标准简介与注意事项
欧盟EN55022:2006EN55022:2006(CISPR22:2005)在欧盟（EuropeanUnion，EU）自2009年10月1日正式生效。
现在相关的辐射干扰(radiateddisturbances)测试范围是由30MHz至1GHz，但是修正案A1:2007将会加入1GHz至6GHz的测试范围，并于2010年10月1日生效。
因此在测量辐射干扰时，将采用30MHz至6Ghz的频段。
修改EN55022:2006所产生的影响CISPR22(theComiteInternationalSpecialdesPerturbationsRadioelectriques,orInterna tionalSpecialCommitteeonRadioInterference,国际无线电干扰特别委员会)是适用范围最广的一项重要的EMC(electromagneticcompatibility，电磁兼容)标准，并对资讯科技设备(info rmationtechnologyequipment，ITE)提出了一些要求，其中包括了「电讯装备和个人电脑」(telecommunicationsapparatusandPCs)。
EN55022:2006将于2009年10月1日在欧盟(EU)生效，并包括多项修改；例如：制定了有关新的电讯ISN设计的要求，及删除了在「辐射放射测试」(radiatedemissiontestin g)中对「铁氧体磁管」(ferritetube)的要求。
于2010年10月1日，EN55022:2006的修正案A1:2007亦会生效，届时将引入1G Hz至6GHz的测试范围。
该修正案对频段1GHz至6GHz的「辐射发射」(radiatedemissi on)作出了限制性规定。
由于许多国家都以CISPR22作为基础制订其国家的资讯科技设备的放射规定，所以上述修订将进一步影响世界市场。
现在，台湾(BSMI)和日本(VCCI)亦将从2010年4月1日起，要求测试超过1GHz的辐射放射，及使用与CISPR相同的测试方法和限制规定。

欧盟EN55022标准简介与注意事项
欧盟EN55022标准简介与注意事项第一篇：欧盟EN55022标准简介与注意事项欧盟EN55022:2006EN55022:2006(CISPR22:2005)在欧盟（EuropeanUnion，EU）自2009年10月1日正式生效。
现在相关的辐射干扰(radiateddisturbances)测试范围是由30MHz至1GHz，但是修正案A1:2007将会加入1GHz至6GHz的测试范围，并于2010年10月1日生效。
因此在测量辐射干扰时，将采用30MHz至6Ghz的频段。
修改EN55022:2006所产生的影响CISPR22(theComiteInternationalSpecialdesPerturbationsRad ioelectriques,orInternationalSpecialCommitteeonRadioInterfere nce,国际无线电干扰特别委员会)是适用范围最广的一项重要的EMC(electromagneticcompatibility，电磁兼容)标准，并对资讯科技设备(informationtechnologyequipment，ITE)提出了一些要求，其中包括了「电讯装备和个人电脑」(telecommunicationsapparatusandPCs)。
EN55022:2006将于2009年10月1日在欧盟(EU)生效，并包括多项修改；例如：制定了有关新的电讯ISN设计的要求，及删除了在「辐射放射测试」(radiatedemissiontesting)中对「铁氧体磁管」(ferritetube)的要求。
于2010年10月1日，EN55022:2006的修正案A1:2007亦会生效，届时将引入1GHz至6GHz的测试范围。
该修正案对频段1GHz 至6GHz的「辐射发射」(radiatedemission)作出了限制性规定。
由于许多国家都以CISPR22作为基础制订其国家的资讯科技设备的放射规定，所以上述修订将进一步影响世界市场。

引言
由于市场对于提升信息技术和通信设备性能的需求，因此如今的系统设计人员面临着必需设计EMI 兼容产品的巨大挑战。
在销售之前，所有通常被规定为具有一个高于9kHz 之已调时钟信号的信息技术设备（ITE）都必须满足相关的政府标准，例如美国的FCC Part 15 Subpart B 和欧盟的EN55022，这些标准规定了工业和商业环境（Class A）以及家庭环境（Class B）的最大可容许辐射发射。
鉴于此类严格的EMI 标准、工程人力资源限制和产品快速上市要求，使得通过EN55022 标准认证之电源模块的普及率有所提高。
然而重要的是必须知晓电源模块在认证时所处的电气操作条件，以避免在之后的设计过程中感到诧异。
对开关模式稳压器中的EMI 干扰源和场强因子有所了解将有助于设计工程师选择最佳的组件，以减轻特别是那些所需电流水平较高之尖端设备中的电磁辐射。

en55022标准
EN 55022是欧洲电磁兼容性（EMC）标准之一，具体规定了信息技术设备（ITE）和广播电信设备的射频骚扰特性的要求。
以下是EN 55022标准的一些详细解释：
适用范围：EN 55022主要适用于信息技术设备（如计算机和外围设备）以及广播电信设备。
这些设备在操作时不应产生过多的电磁骚扰，也不应过于敏感，容易受到外部电磁场的干扰。
射频骚扰特性：标准规定了设备在射频范围内的发射要求，包括辐射和导体传导。
这旨在确保设备不会干扰其它设备的正常运行，也不会受到外部电磁场的不必要干扰。
测量方法：EN 55022详细描述了测量射频骚扰的方法，包括辐射和传导的测量。
这些测量方法有助于制造商和测试实验室验证设备是否符合标准要求。
标识要求：标准还规定了设备应携带的标识，以表明其符合EN 55022的要求。
这有助于消费者和监管机构确认设备是否符合相关的EMC标准。
总体而言，EN 55022的目标是确保信息技术设备和广播电信设备在电磁环境中的互操作性，减少电磁干扰对其正常功能的影响。
