ETS 1000 RFC2544 测试配置方法1．拓扑以下图中的拓扑为例，ETS 1000 的2个端口连接到一台交换机上，因此ETS1000的两个端口IP地址设置在同一个子网内Port A：192.168.1.1/24 Port B: 192.168.1.2/24 (如果被测网络存在路由器，则ETS1000两个端口在不同子网并且配置网关地址)2．测试方法我们举例的方法为通过将PortB 设置为3层环回端口，并且PortA发送测试数据，指定测试数据的源地址为A端口地址，目的地址为B端口地址。

这样测试数据能在A到B 和B到A两个方向上传送得到测试结果。

3．测试配置a)“接口设置”进入后选择A端口和B端口，并且设置Speed 选项，根据需要选择自动或者手动指定10/100/1000. 本例中A端口和B端口都为自动。

如果需要可以进入VLAN和MPLS的菜单进行相应设置b)接口设置完成后进入“网络设置”菜单，如之前拓扑设置A 地址192.168.1.1 和B地址192.168.1.2 (如果被测网络中有路由器则地址应该在不同子网，并设置相应网关地址)c)进入“tools”菜单，设置环回端口，进入菜单选择端口B，设置Layer 为3。

此时，端口B将交换所受到数据包的源地址和目的地址，以便把测试数据发回到A 端口。

d)返回主界面进入“tests“菜单，进入RFC 2544 测试设置e)进入“设置“f)进入“topology“菜单，设置TX和RX port 都为Ag)返回上一级进入“Header“，设置Src MAC 和IP 为A，Dst MAC和IP 为Bh)返回上一级进入“Frames“并选择需要测试的帧大小i)返回上一级进入“Throughput“，设置传输的速率“Rate”，测试时间“Trial，S”RFC2544 推荐为60秒以上j)返回并进入“Latency”，设置测试时间“trial,s”并设置测试速率“Rates”为Throughput。

EXFO ETS-1000 操作简介在使用ETS-1000 做测试，一般可以分成3个步骤：1.确定连接拓扑。

常用的连接有如下方式：a)双仪表方式。

在这种方式下，一般仪表1用来发送接收数据，仪表2做环回，可以根据需要做2层环回（及将收到数据包的源MAC地址和目标MAC地址做交换）或者3层环回（将收到数据包的源IP地址和目标IP地址做交换，MAC地址做相应改变）。

b)单仪表方式。

这种方式中，仪表2个端口都连接到待测网络中，每个端口设置不同的IP和MAC地址，一个做源一个做目的，完成测试。

2.设置端口参数。

如图在设置界面设置网络参数和接口参数a)在网络设置中设置IP地址，子网掩码，网关地址参数b)在接口设置中设置MAC地址， 10， 100，1000M速率模式，以及是否要启用VLAN，以及VLAN ID3.设置测试类型a)RFC-2544 测试为业界衡量网络性能的主要标准，通过吞吐量，背对背，延迟和帧丢失等方面来衡量网络性能。

b)混合流量可以允许客户设置最多10条数据流，指定不同流的字节，速度等具体参数真实模拟网络流量，衡量网络性能。

i.在混合模式配置界面设置数据流的数量Stream 可选择1到10条数据流， Duration 设定数据流生成的时间ii.进入Topology 设定发送数据端口和接收数据端口，收发端口可以不同也可以相同iii.进入header 设置MAC地址和IP地址iv.进入Frame 设置每个数据流的大小v.最后在Rate 菜单中设置每个数据流的速率然后在混合流量->测试中开始测试，可以得到如下结果：c)BERT 误码率测试，允许发送特定的二进制码率，通过发送接收端的对比统计出误码的比特，比率等信息。

最后的测试实例有配置介绍。

d)数据包抖动，根据RFC4689的原理测试数据包在线路上的延迟差异，这种测试对延迟敏感的数据流如语音视频数据特别重要。

e)测试流量是用来生成流量拱数据包抖动测试使用，可以单端口发送接收或者从A端口发送的B端口两种模式。

To close, place the battery pack with the top end in first. Now push down on the bottom end of the battery pack ensuring that it is firmly in place. Now push the clip firmly towards the bottom of the test set until it clicks into place. Charge the ETS battery using the supplied USB cable connection and wall charger, connect as shown below. Charge for 2 to 3 hours. Upon power-up, follow on screen directions for initialization and setting the time. The initialization routine is very important to ensure proper function of the stylus on the test set screen.Page 5 of 24Palm™ Desktop SoftwarePrior to use, the Palm™ Desktop Software as supplied on the CD-ROM disc (Artex P/N 510-1200) supplied must be installed on your Windows95/NT/98/2000/Me/XP PC that will be used to interface with the ETS. Follow the on-screen instructions for installation.Note: The Palm desktop software works most amiably if a single Meazura (Palm) device is associated with a single computer. It is possible to use more than one Meazura (or Palm) device with the same computer but attention must be given to the selection of appropriate user names when transferring data to and from different units. The Palm software identifies the User Name when the Palm Desktop application is installed on a PC. Only one User Name can be used with the Artex applications.Sarcalc DesktopThe Sarcalc Desktop application SarCalc Desktop V1.2 (or higher) may also be installed on a PC (available free for download at ). Once installed, the entire Sarcalc or Artex database can be reviewed. Note: The Meazura unit must be HotSync'd with the Palm Desktop software to load the database from the Meazura unit to the PC. Once sync'd, the database can be opened on the PC by starting the SarCalcDesk.exe application and opening the database from the file menu. The Palm HotSync will usually store the database file inC:\ProgramFiles\Palm\Artex\Backup\ (where Artex is the Meazura user name. Be sure to use the “Artex” user name whenever performing a “HotSync”. All Artex provided software is loaded to the Meazura using this user name.) The database will be named SarcalcDB.PDB. If the Meazura was set-up on the PC with a different User Name than “Artex”, check the folder for that User Name to locate the Backup file to find the Sarcalc and Artex database information.Hot SyncOnce installed and configured, the Palm™ Desktop Software will allow installation of additional software applications as well as performing the hot sync function to transfer data to and from the ETS (Meazura unit). Artex provides a USB cable (452-0103) to connect to a PC. The hot sync function is accessed by tapping thePage 7 of 24Maintaining your Battery PackBattery UsageThe Meazura™ MEZ1000 RDA comes with a custom rechargeable Lithium Ion battery pack that can only be purchased from Aceeca or Artex. The battery pack allows about 60 hours of continual use.Battery Warnings•D o not heat or throw the battery into a fire.•D o not use or store the battery close to fire or inside a car in which the temperature may be over 60°C.•D o not put the battery in your pocket or in a bag together with metal objects such as necklaces, hairpins, coins, or screws. Do not store the battery with such objects.•D o not short circuit the (+) and (-) terminals with a metal object such as a needle, necklace or hairpin.•D o not pierce the battery with a sharp object such as a nail.•D o not hit with a hammer, step on, throw, drop or allow the battery to undergo other such strong shock.•D o not disassemble or modify the battery.•D o not solder the battery directly.•D o not use a battery that is severely scarred or deformed.Battery StorageUnlike NiCad (Nickel Cadmium) batteries or NiMH (Nickel-metal Hydride) batteries, lithium-ion batteries should be charged early and often. Never use battery maintenance software to maintain your battery as this can reduce the life of your battery. Li-ion batteries should be kept cool. They should not be subjected to freezing temperatures. Aging will occur much faster at high temperatures (such as a hot car) and will reduce the life of your battery. Purchase a Li-Ion battery pack only when you need a replacement, ensuring you receive a fresh battery pack.•S top using the battery if it exhibits abnormal heat, odor, color, deformation or is in an abnormal condition.•K eep away from fire immediately when leakage or foul odor is detected.•I f liquid leaks onto your skin or clothes, wash well with fresh water immediately.•I f liquid leaking from the battery gets into your eyes, do not rub your eyes.Wash them well with clean water and consult a doctor immediately.•B efore using the battery, be sure to read the user's manual and cautions onPage 9 of 24Recycle and Disposal MethodsLithium ion batteries, like all rechargeable batteries are recyclable and should be recycled.CAUTIONIf your battery is damaged, or if it no longer holds a charge, dispose of it promptly and properly. Do not dispose of it along with general waste. Call your local waste disposal agency or environmental agency for advice on disposing of the battery.Page 11 of 24Waiting for Data” Screen ViewOnce a valid message is received, all encoded data is displayed on the screen as shown below.

More and more sensors are added to vehicles as the future of transportation moves towards higher level of automation. Reliability and quality of time critical communications between different systems are nowadays under the spotlight, and Ethernet cables have become the industry standard to support the network within the car.The Open Alliance TC9 compliance specification is regarded as a qualificationbenchmark for unshielded twisted pair (UTP) cables for Automotive Ethernet [1].This document contain electrical requirements and measurement specifications on1000BASE-T1 channel and components link segment type A (UTP). It shall be used as a standardized common scale for the evaluation of the RF properties for physical layercommunication channels to enable 1000BASE-T1 technology.The focus of this application note is to describe the method of performing compliance tests according to the TC9 specification for Ethernet cable testing. Chapter 2 describes the test setup required to perform measurements on 1000BASE-T1 coaxial cablesusing the four-port ZNB4 Vector Network Analyzer (VNA) from Rohde & Schwarz.Chapter 3 explains the procedure of calibrating the VNA and checking the VNAcalibration accuracy. Finally, in chapter 4, measurement examples from the OpenAlliance TC9 compliance specification are shown.AbbreviationsThe following abbreviations are used in this application note for Rohde & Schwarzproducts:▪The R&S®ZNB4 Vector Network Analyzer is referred to as ZNB▪The R&S®ZN-Z51 Automatic Calibration Unit is referred to as ZN-Z51▪The R&S®ZV-Z135 Calibration Kit is referred to as ZV-Z135▪Device Under Test is referred to as DUTTest Setup 2Test SetupFig. 2-1: Test setup for performing TC9 measurementFig. 2-1 shows the measurement setup required to test 1000Base-T1 AutomotiveEthernet cables. The Ethernet cables are unshielded coaxial twisted pair cables and in order to perform measurements, a PCB based measurement fixture (adapter board) is used to adapt to the connectors of the Rohde & Schwarz ZNB4 Vector NetworkAnalyzer to the test cables.To start a measurement, the test setup needs to be calibrated. A full 4-port systemerror correction would ensure calibration up to the reference planes 1. A measurement between these two planes (marked in blue in Fig. 2-1) would include an undesired RF response of the adapter boards. The compensation of this effect is optional according to the Open Alliance specification. This application note shows a method to "de-embed" the adapter boards, in order to obtain a reference plane calibrated at theEthernet cable ends (marked in red in Fig. 2-1).The VNA configuration and measurement parameters are documented in the Open Alliance TC9 specification, while a systematic guide on how to calibrate and configure the ZNB4 is described in the next chapters of this document.3Calibrating and Configuring the VNA forMeasurementThe first step of any test performed with a VNA consists in calibrating the instrument.As a measure of good practice, let the VNA and the calibration unit warm up about one hour to gain stable characterization data. To obtain the required VNA calibrationaccuracy a manual calibration is usually performed but automatic calibration units can be used with the method described in the next paragraph as well. If a manualcalibration is preferred, you can ignore paragraph 3.1.The VNA needs to be configured to the settings defined in table: 4.2-2 of the OpenAlliance TC9 test specification [1].3.1 Characterization of the Calibration UnitIn order to obtain optimal calibration accuracy with an automatic calibration unit (e.g.ZN-Z51) the generation of specific characterization data of the unit is recommended. In order to do this, the user needs perform a calibration with a manual calibration kit (e.g.ZV-Z135) first. This will ensure a full system error corrected VNA and enable precisecharacterization of the calibration unit. Use the setting from [1] table 4.2-2.Fig. 3-1shows the port connections of ZNB4 with the automatic calibration unit ZN-Z51.Fig. 3-1: Setup for a Full 4-Port automatic system error calibration of the ZNB4 using ZN-Z51Then start the characterization step by disconnecting the manual calibration kit and connecting the automatic one as shown in Fig. 3-1ıTo start the characterization step, press▪CHANNEL > Calibration > Cal Devices > Characterize Cal Unit▪Select Start Characterization as shown in Fig. 3-2Fig. 3-2: Calibration unit Characterization configurationA list of all the saved characterization datasets can be found on the left of thewindow as shown aboveıPress Test Port Assignment > AutomaticıSelect Take all OSM and ThroughıSave the characterization data file on the unit▪In this example, the name "full log 2001 11.37" was usedıAfterwards, the ZN-Z51 can be used for future calibrations as follows: ▪Use the same settings as described in the standard▪Select Channel > Cal > Start (Cal Unit)▪Select all 4 ports P1, P2, P3 and P4 as shown in Fig. 3-3▪Use the characterization data generated and saved before (in this example "full log 2001 11.37")▪Select Next and follow the instructions on the screenFig. 3-3: Configuration for calibrating all four ports of the ZNB4At this point, the instrument is calibrated up to the calibration reference plane 1 in Fig.3-4. This step needs to be done only once for a calibration unit. For every newcalibration from this point onwards, the same characterization data can be used.3.2 Optional de-embedding of fixture boardsWhen the adapter boards are connected to the ZNB, the influence of the two microstrip lines up to calibration reference plane 2 can be eliminated, to obtain a measurement of the Ethernet cable only.In order to do that, connect the adapter board to the ZNB4 as shown in Fig. 3-4▪Connect P1 and P3 to adapter board 1▪Connect P2 and P4 to adapter board 2Fig. 3-4: Different calibration planes on the adapter boardTo compensate for the influence of the fixture on the measurement result, the de-embedding functionality of the ZNB can be used. The de-embedding is done in balanced mode.▪Select Measurement > Balanced Ports > (D) 2 x Balanced▪Trace > Measurement > Sdc11▪Trace Config > Add Trace▪Trace > Measurement > Sdc22▪Offset Embed > Offset > Fixture Compensation…▪Select all four ports▪Choose Offset correction: "Direct Compensation"▪Press Measurement Type: "Open"▪Press "Take" and close the dialog once the process ended"Direct Compensation" provides a frequency-dependent transmission factor. "Auto Length and Loss" uses a global electrical length and loss, so compensation is based on a transmission line model.Depending on the fixture itself, additional measures can be taken to improve the compensation result. See the R&S® ZNB/ZNBT Vector Network Analyzer User Manual for further information on the compensation approaches of the ZNB.Fig. 3-5: Mode Conversion Sdc11 and Sdc22 with open fixture after Fixture Compensation with"Direct Compensation"The microstrip lines on the adapter boards are now compensated and Fig. 3-5 shows the conversion loss values after the process. The calibration is now shifted up tocalibration reference plane 2.3.3 Verification of VNA Calibration AccuracyAfter the calibration procedure, the ZNB4 needs to be configured to balanced porttesting mode. The ZNB4 port P1 and port P3 are configured as logical port L1 and port P2 and port P4 are configured as logical port L2.▪Click Trace > Measure > Balanced Ports▪Select the configuration as shown in Fig. 3-6▪Choose reference impedance and change common mode impedance to 200Ohm as indicated in the Open Alliance specification, then hit okFig. 3-6: Balanced port configuration for the ZNB4Now the VNA calculates the mixed-mode S-parameters from the measured single-ended S-parameters and shows them in the diagram areas.At this point, a verification step needs to be performed to check the calibration accuracy of the VNA. The verification of VNA calibration accuracy is performed with two "THRU" connectors as per Open Alliance specification.Fig. 3-7 shows the calibration accuracy verification of the ZNB4 for return loss, longitudinal conversion loss and longitudinal conversion transfer loss. All values are within the limits defined in the specification.The option ZNB4-B54 "Extended Dynamic Range" improves the dynamic range of the instrument by circa 10 dB. The VNA accuracy verification test will show 5 dB lower conversion loss in this case. The result shown in Fig. 3-7 is measured without this option.Calibrating and Configuring the VNA for Measurement Fig. 3-7: Verification of calibration accuracy of return loss, longitudinal conversion loss and longitudinal conversion transfer loss4Measurement and ResultsAs an example of measurement, the return loss and insertion loss of an Ethernet cable are taken into consideration. The measurement of CIDM (Characteristic ImpedanceDifferential Mode) is also explained in the following paragraphs. The fixtures used inthe following example meet the requirements of [1].4.1 Measurement of Mixed-Mode S-ParametersIf all the steps in the previous chapters have been correctly performed, the setup isfully calibrated and configured to measure as described in Open Alliancespecifications.First, connect the Cable Under Test (CUT) as shown in Fig. 2-1.Fig. 4-1: Return loss measurement of 1000BASE-T1 according to TC9 specIn order to measure return loss or insertion loss,▪Select the corresponding S-parameter from Trace > Measurement> S-parameterFig. 4-2: Insertion loss measurement of a 1000BASE-T1 Automotive Ethernet cableFig. 4-1 and Fig. 4-2 show the return loss and insertion loss measurement of a1000BASE-T1 Automotive Ethernet cable using the ZNB4.4.2 Measurement of TDR based CIDM (CharacteristicImpedance Differential Mode)To carry out impedance measurements, the recommended VNA configurationaccording to [1] is different than the one used for the S-parameter measurements. One reason is that a linear frequency sweep is needed for converting the measurementresult from frequency domain into time domain with the Inverse Fourier Transform,while for the S-parameter measurement described above, a logarithmic sweep is used.Additionally, a higher stop frequency is advantageous for a higher resolution (shorter rise time) in the TDR.A second measurement channel can be calibrated and used to see TDR results on theVNA screen in parallel to the S-parameters. The second channel (Ch2) can beconfigured with different settings.To do thisıSelect Channel > Channel Config > Add Ch+Tr+Diag▪Ch2 is now indicated in the lower left corner of the diagram area▪Configure the VNA according to the specification of [1]▪Perform calibration (if an automatic cal unit is used, use "factory" from the characterization pool)The two channels will run sequentially.While using the active trace in Ch2 set up an impedance trace in time domain to perform the CIDM measurement by▪Meas > Z Sdd11, choose Sdd11 from the drop down menu▪Trace > Trace Config > Time Domain and check box "Time Domain"▪Choose Type "low pass step" from the drop down menu▪Press "Low Pass Settings…" and check box DC Value "Continuous extrapolation"▪Stimulus > Stop to adapt the stop time to the DUT. Electrically long DUTs need a longer analysis timeFig. 4-3: Typical CIDM measurement based on time domain measurement of an automotiveEthernet cableIn Fig. 4-3, a typical result of the impedance measurement of an automotive Ethernet cable is shown. The differential reference impedance of 100 Ω is seen up to0 ns. Then a segment with around 99 Ω corresponds to the left fixture. The cable impedance of around 96.5 Ω can be seen in the section between 2.5 ns to 3 ns followed by the right fixture with an impedance of about 100Ω.Reference5Reference[1] Link Segment Type A (UTP) 1000BASE-T1 Ethernet Channel and ComponentsSpecification - TC9, Open Alliance, Weblink: /tech-committees/tc9/Ordering Information 6Ordering InformationRohde & Schwarz The Rohde & Schwarz electronics group offersinnovative solutions in the following business fields: test and measurement, broadcast and media, secure communications, cybersecurity, radiomonitoring and radiolocation.
