Section 1 contains a general description of the equipment. Section 2 containsinstallation instructions. Section 3 contains operating instructions. Section 4 providesthe theory of operation. Section 5 contains maintenance and troubleshooting information.Figure 1 and Figure 2 show front and rear views of these modems.Figure 1: Front ViewFigure 2: Rear View1.2 DESCRIPTION OF EQUIPMENT1.2.1 Functional CharacteristicsModel F2238A and F2245A modems are high-speed modems that allow the full duplex transmission of data, clock and a control signal (data terminal ready (DTR), data set ready/data carrier detect (DSR/DCD)) over fiber optic cable. Table 4 shows the modem link configuration.The fiber circuit consists of two modems connected by two fiber optic strands with data rates and electrical signal characteristics that conform to EIA RS-530 and MIL-STD-188-114 balanced/unbalanced standards. The modems provide synchronous or asynchronous datatransmission at speeds up to 10 Mbps. The link is fully transparent in both directions and is data agile. The F2238A is for use with muti-mode fiber and utilizes and 850nm SFP fiber optic module with LC connectors. The F2245A is for use with single-mode fiber and utilizes a 1310nm SFP fiber optic module with LC connectors. Basically, model F2238A and F2245A modems operate as two channel multiplexers/modems. For high-speed synchronous operation the first channel is used for data and the second for transmit clock. The data channel may be used for data in low-speed, asynchronous operation at less than 100 Kbps.1.2.2 Physical CharacteristicsModel F2238A and F2245A modems measure 7 x 1 x 11 in. WxHxL (17.8 x 2.5 x27.9 cm). They are designed to be mounted in VERSITRON’s FOM II Series HFenclosures and chassis (see Table 1). Model HF-1 (single card) desktop enclosures areavailable for standalone applications. Standard 19" rack mountable options include modelsHF-2SS (2-slot) and HF-20A (20-slot) chassis. Each modem installed in models HF-1 orHF-2SS requires its own V AC to VDC power adapter. Each power adapter uses the one-pin connector on the back of the modem for power input. (Customer provided power maybe supplied to the modem using the same one-pin connector.) When installed into the HF-20A chassis model AC300WR power supply is used to provide power to the chassis and tothe modems. Power is provided from the AC300WR power supply to the HF-20A chassisvia model HF-CA3 power interface cable where it is then distributed to any FOM II Seriesmodem installed in the chassis. Power redundancy is included with the AC300WR powersupply with two separate AC input cables provided for power input from separate V ACsources. The RS-530 copper interface is a female DB25 connector and is located on theback of the modem. The fiber optic interface, also located on the back of the modem,consists of an SFP cage which is populated with an SFP fiber optic module. Model F2238Aand F2245A Modems have seven indicator LEDs (see Figure 1): power on (PWR), alarmindicator (ALM), transmit data present (TXD), receive data present (RXD), transmit clockpresent (TXC), receive clock present (RXC), and loop-back indicator (LOOP).Table 1: Dimensions of Enclosures and Chassis*² Note: One Power Supply per Modem required.1.3 Modem Specification:1.3.1 General Specifications:1.3.2 Electrical Interface:1.3.3 Fiber-Optic Interface:F2238A: multi-mode 850nm LC connectors, 2km.F2245A: single-mode 1310nm LC connectors, 10km.1.3.4 Major Features:2 INSTALLATION2.1 GENERALThis section contains detailed information on the installation and initial checkout of the F2238A and F2245A EIA-530 Modem. Section 2.2 contains general information on site selection and mounting. Section 2.3 contains the description for selecting different options on the Modem.Sections 2.4 and 2.5 contain detailed instructions for connecting Model F2238A and F2245A products to your system. Section 2.6 contains initial checkout procedures.2.2 SITE SELECTION AND MOUNTINGThe Model F2238A and F2245A products are designed to be used as an interface extender for EIA-530 and MIL-STD-188-114 standard protocols. When connecting the F2238A and F2245A to a DCE or DTE device, the copper and fiber-optic cable should be securely installed so as to prevent accidental disconnection. Care should be taken to ensure that the copper and fiber-optic cables are not mechanically separated from the Modem during operation. When installed in either desktop chassis or in the dual-card rack-mount chassis, space for the power transformer must also be provided.2.3 SWITCH AND JUMPER SETTINGSThere are ten switches provided for configuration of selectable options. Switch locations are shown in Figure 3. Switch settings are as follows:2.3.1 Modem Configuration SettingsTable 2: S1 Switch SettingsTable 3: S2 to S9 Switch SettingsThe switch SW10 is located on the front panel of the modem. This switch enables a local loop of all modem circuitry before the fiber-optic module when in the on position. The loop indicator will be illuminated when this switch is in the ON position. Note: The ALM indicator with be illuminated when the loop switch is enabled.Figure 3: Switch and Connector Locations2.4 POWER REQUIREMENTSThe F2238A and F2245A products are designed to operate from an AC power transformer or a DC power source in the range of +10 to +16 VDC.2.4.1 Installation with AC PowerBefore inserting the VERSITRON power transformer, PSAC08 (US) or PSAC09 (EUR), into an AC power source, the plug should be connected to the Modem. There are no special tools required.2.4.2 Installation with DC PowerDC power may be used instead of a power transformer. This requires a 2.5 mm socket, J3(location shown in Figure 3) with the positive voltage on the center and the common on the concentric supplying 12VDC at 1.0A as shown below (Figure 4):Figure 4: DC Power Supply Connection2.5 INTERFACE WIRINGTable 4 and Table 5 list the interface wiring for the F2238A and F2245A Modems.A female DB25 connector is used as shown in Table 4. The modular connector (J3) is wired inparallel with the 12-pin connector (P1) for power. When installing the modem in a standalone or dual-card rack-mount chassis, a power transformer is plugged into modular jack (J3). When installing the F2238A and F2245A Modems in a 20-card rack-mount chassis (HF20A) with optional power supplies (AC300WR) the 12-pin connector (P1) is used. Wiring for the 12-pin connector is shown in Table 5. Illustration 3 identifies the locations for the 12-pin power connector (P1) and modular power jack (J3).Table 4: F2238A and F2245A Data InterfaceReceive Data (A)<—<—Transmit Data (A)Receive Data (B)<—<—Transmit Data (B)Receive Clock (A)<—<—Terminal Timing (A)Receive Clock (B)<—<—Terminal Timing (B)Transmit Data (A)—>—>Receive Data (A)Transmit Data (B)—>—>Receive Data (B)Terminal Timing (A)—>—>Receive Clock (A)Terminal Timing (B)—>—>Receive Clock (B)Signal Ground<—><—>Signal GroundData Set Ready (A)*<——>Data Set Ready (A)*Data Set Ready(B)*<——>Data Set Ready (B)*Data Terminal Ready (A)**—><—Data Terminal Ready (A)**Data Terminal Ready (B)**—><—Data Terminal Ready (B)**Carrier Detect (A)*<—<—Carrier Detect (A)*Carrier Detect (B)*<—<—Carrier Detect (B)*Frame Ground<—><—>Frame GroundLOCAL MODEM DCE DTE REMOTE MODEM* Produced by local modem, not received from remote modem.** Signal not physically passed, used to control signal flow through local modem.Table 5: (P1) Chassis Power/Alarm Wiring2.5.1 Fiber-Optic Cable InstallationAfter the electrical and digital interface cables have been wired according to sections 2.4and 2.5 , make sure the SFP module is firmly seated into the SFP cage (Z1) and attach the fiber-optic cable to it (see Figure 3 for location of Z1). The SFP module slides into the RFI Cage label side up. There will be a slight click when it locks into place. After the SFP module is installed the fiber-optic cable can be installed. The cable must be an LC type connection. The cable should be oriented with the thumb tab at the top, when completely inserted the tabs will click into place.2.6 INITIAL CHECKOUT PROCEDUREF2238A and F2245A Modems contain no power on/off switch. Once power is connected the modem will go through its power-up sequence, when the Power LED (see Figure 1) is lit the modem is ready for use. Before beginning system operation check the following to verify proper installation:1.Verify that the power plug is seated fully into the modem or the modem is seated fully in therack-mount enclosure (HF20A).2.Verify that the fiber cable is connected on each end.3.Verify that the Alarm LED (see Figure 1) is not lit when the fiber-optic cable is connected andthe units, both local and remote, are powered.DSR/DTR must be asserted or forced via S1-7.If a malfunction is detected during the initial checkout procedure, refer to Section 5 for information on isolating the malfunction in the unit.3 OPERATION3.1 INTRODUCTIONThis chapter contains a description of the operating controls and indicators associated with the F2238A and F2245A Modems. Since the F2238A and F2245A are designed for continuous and uninterrupted operation, there are no setting requirements after the unit is operational. Once the Modem is powered up it should remain in service as long as required.3.2 STATUS INDICATORSThere are 7 indicators on the F2238A and F2245A: Power Status(Power), Alarm, Transmit Data(TXD), Receive Data(RXD), Transmit Clock(TXC), Receive Clock(RXC), and Loop-back(LOOP) (see Table 6 for descriptions).Table 6: Status Indicators4 THEORY OF OPERATION4.1 INTRODUCTIONThe F2238A and F2245A are EIA-530/MIL-STD-188-114 standard modems which can be configured as either Data Communications Equipment (DCE) or Data Terminal Equipment(DTE). These modems are designed to be used in pairs as a transparent interface extension overa fiber-optic link. These units are housed in VERSITRON FOM II chassis: HF1, HF2SS andHF20A. Chassis descriptions are found in section 1.2.2 .4.2 POWER SUPPLY AND ALARM CIRCUITRY4.2.1 Power Supply CircuitWhen 12VDC is applied to the circuit, the unit should draw approximately 100mA. The unit has a switching power supply circuit, which converts 12V to 3.3VDC, and 1.2VDC. .4.2.2 Alarm CircuitThis unit does not have an alarm circuit. Therefore, the Alarm signal on the AC300WR will not be driven by this unit.4.3 FUNCTIONAL DESCRIPTIONThe unit consists of the following circuits:4.3.1 - Logic Conversion4.3.2 - FPGA (Mux/Demux)4.3.3 - Fiber-Optic Transceiver Circuit4.3.1 Logic ConversionThere is a transceiver chipset that converts the EIA-530 interface signals to logic level signals for processing and transmission over the fiber-optic link.4.3.2 FPGA (Mux/Demux)The FPGA is used to multiplex/demultiplex the RS interface signals from the chipset for transmission over the fiber-optic link. The FPGA is a proprietary VERSITRON design that provides serial conversion and synchronization of the EIA-530 interface signals on the fiber-optic link.4.3.3 Fiber-Optic Transceiver CircuitFiber-optic communications are handled by the SFP module. The power for this module is isolated from the other power circuits through filters. This helps reduce the supply noise being coupled into the SFP module. The SFP interfaces directly with the FPGA.5 MAINTENANCE AND TROUBLESHOOTING5.1 INTRODUCTIONThis chapter contains general information designed to isolate a malfunction in the Models F2238A and F2245A to a replaceable unit. These units are not equipped with redundancy.Therefore, a failure in one of these units will interrupt service.5.2 FAULT ISOLATIONThe steps in Table 7 should be taken to check a non-operating modem.

汽车用电器熔断器及连接导线间的匹配设计
汽车用电器熔断器及连接导线间的匹配设计电器系统在汽车中扮演着至关重要的角色，其质量和可靠性直接影响着汽车性能和安全性。
熔断器是电器系统的关键部件之一，其作用是在系统受到过大电流冲击时，通过断开电路来保护系统不受损坏，从而起到保护汽车和乘客的作用。
因此，熔断器的选择和连接导线的匹配设计至关重要。
首先，选择正确的熔断器是设计的第一步。
要选择符合汽车电气系统要求的，稳定可靠的熔断器。
熔断器的电流容量必须与电气系统的电流要求相匹配。
如果熔断器的电流容量太小，可能因系统中的过大电流而导致熔断器的熔丝烧断，从而使电器系统无法正常工作；如果熔断器的电流容量太大，则可能会导致熔断器在系统故障时无法断开电路，从而导致电气设备的过载损坏，甚至引起火灾。
因此，在选择熔断器时，要仔细了解汽车电气系统的电流要求，确保选取正确的熔断器。
其次，熔断器与连接导线之间的匹配设计也很关键。
连接导线与熔断器之间的截面积必须匹配。
如果熔断器和连接导线之间的截面积不匹配，会导致电线过热，引起线路失火。
为了保证汽车电气系统的安全可靠，连接导线的厚度和长度也必须得到适当的考虑。
如果连接导线太细，则无法承受过载电流，从而导致线路烧断，影响整个汽车系统的正常工作。
一般而言，连接导线的选择应遵循以下原则：1.必须匹配电气设备的功率和电流；2.必须选择符合要求的导线材料，在保证导线功能的同时可靠性能；3.导线的长度应符合要求，且应保证导线不承受系统过载电流。
如果导线太长，会增加电气系统的电阻，从而降低系统效率，影响汽车性能和安全。
总之，汽车电气系统中的熔断器和连接导线之间的匹配设计是确保汽车电气系统正常工作、安全可靠的重要环节。
因此，在设计汽车电气系统时，必须考虑电气设备的功率、电流、导线的截面积、材料、长度等因素，并合理选择熔断器和连接导线。
只有在这些方面合理匹配的情况下，汽车电气系统才能实现高效稳定的工作，为汽车的性能和安全保驾护航。
在实际的汽车电气系统中，熔断器和连接导线的匹配设计是非常重要的。

电缆选型手册及常用公式
电缆选型手册及常用公式电缆的选型与配线选择电线平方数和电流一般铜线安全电流最大为：2.5 平方毫米铜电源线的安全载流量－－28A。
4 平方毫米铜电源线的安全载流量－－35A 。
6 平方毫米铜电源线的安全载流量－－48A 。
10 平方毫米铜电源线的安全载流量－－65A。
16 平方毫米铜电源线的安全载流量－－91A 。
25 平方毫米铜电源线的安全载流量－－120A。
如果是铝线截面积要取铜线的 1.5-2 倍。
如果铜线电流小于 28A，按每平方毫米 10A 来取肯定安全。
如果铜线电流大于 120A，按每平方毫米 5A 来取。
导线的截面积所能正常通过的电流可根据其所需要导通的电流总数进行选择，一般可按照如下顺口溜进行确定：十下五,百上二, 二五三五四三倍,七零九五两倍半,铜线升级算.就是 10 平方以下的铝线,平方毫米数乘以 5 就可以了,要是铜线呢,就升一个档, 比如 2.5 平方的铜线,就按铝线 4 平方计算.一百以上的都是截面积乘以 2, 二十五平方以下的乘以 4, 三十五平方以上的乘以 3, 70 和 95 平方都乘以 2.5,这么几句口诀应该很好记吧, 说明:只能作为估算,不是很准确。
另外如果按室内记住电线 6 平方毫米以下的铜线，每平方电流不超过 10A 就是安全的，从这个角度讲，你可以选择 1.5 平方的铜线或 2.5 平方的铝线。
10 米内，导线电流密度 6A/平方毫米比较合适，10-50 米，3A/平方毫米,50-200 米，2A/平方毫米，500 米以上要小于 1A/平方毫米。
从这个角度，如果不是很远的情况下，你可以选择 4 平方铜线或者 6 平方铝线。
如果真是距离 150 米供电（不说是不是高楼），一定采用 4 平方的铜线。
导线的阻抗与其长度成正比，与其线径成反比。
请在使用电源时，特别注意输入与输出导线的线材与线径问题。
以防止电流过大使导线过热而造成事故。
导线线径一般按如下公式计算：铜线： S= IL / 54.4*U`铝线： S= IL / 34*U`式中：I——导线中通过的最大电流（A）L——导线的长度（M）U`——充许的电压降（V）S——导线的截面积（MM2）说明： 1、U`电压降可由整个系统中所用的设备范围内，分给系统供电用的电源电压额定值综合起来考虑选用。
【VIP专享】电线电缆种类及选型计算
电线电缆种类及选型计算电线电缆的定义及分类广义的电线电缆亦简称为电缆。
狭义的电缆是指绝缘电缆。
它可定义为：由下列部分组成的集合体，一根或多根绝缘线芯，以及它们各自可能具有的包覆层，总保护层及外护层。
电缆亦可有附加的没有绝缘的导体。
我国的电线电缆产品按其用途分成下列五大类：1.裸电线；2.绕组线；3.电力电缆；4.通信电缆和通信光缆；5.电气装备用电线电缆。
电线电缆的基本结构：1.导体：传导电流的物体,电线电缆的规格都以导体的截面表示。
2.绝缘：外层绝缘材料按其耐受电压程度。
工作电流及计算电(线)缆工作电流计算公式：单相I=P÷(U×cosΦ)P-功率(W)；U-电压(220V)；cosΦ-功率因素(0.8)；I-相线电流(A)。
三相I=P÷(U×1.732×cosΦ)P-功率(W)；U-电压(380V)；cosΦ-功率因素(0.8)；I-相线电流(A)。
一般铜导线的安全截流量为5-8A/平方毫米，铝导线的安全截流量为3-5A/平方毫米。
在单相220V线路中，每1KW功率的电流在4-5A左右，在三相负载平衡的三相电路中，每1KW功率的电流在2A左右。
也就是说在单相电路中，每1平方毫米的铜导线可以承受1KW功率荷载；三相平衡电路可以承受2-2.5KW的功率。
但是电缆的工作电流越大，每平方毫米能承受的安全电流就越小。
电缆允许的安全工作电流口诀：十下五（十以下乘以五）。
百上二（百以上乘以二）。
二五三五四三界（二五乘以四,三五乘以三）。
七零九五两倍半（七零和九五线都乘以二点五）。
穿管温度八九折（随着温度的变化而变化,在算好的安全电流数上乘以零点八或零点九）。
铜线升级算（在同截面铝芯线的基础上升一级,如二点五铜芯线就是在二点五铝芯线上升一级,则按四平方毫米铝芯线算）。
裸线加一半（在原已算好的安全电流数基础上再加一半）。

或通信速率的提高，其不良影响会越来越严重，主要原因是信号在各支路末端反 射后与原信号叠加，会造成信号质量下降。
注意总线特性阻抗的连续性，在阻抗不连续点就会发生信号的反射。下列几 种情况易产生这种不连续性：总线的不同区段采用了不同电缆，或某一段总线上 有过多收发器紧靠在一起安装，再者是过长的分支线引出到总线。总之，应该提 供一条单一、连续的信号通道作为总线。
RS-485是一种在工业上作为数据交换的手段而广泛使用的串行通信方式，数据信 号采用差分传输方式，也称作平衡传输，因此具有较强的抗干扰能力。它使用一 对双绞线，将其中一线定义为A，另一线定义为B。
通常情况下， RS-485的信号在传送出去之前会先分解成正负对称的两条线路（即我们常说 的A、B信号线），当到达接收端后，再将信号相减还原成原来的信号。发送驱动器A、B之间的 正电平在+2～+6V，是一个逻辑状态；负电平在-2～-6V，是另一个逻辑状态；另有一个信号地 C，在RS-485中还有一“使能”端。“使能”端是用于控制发送驱动器与传输线的切断与连接。 当“使能”端起作用时，发送驱动器处于高阻状态，称作“第三态”，即它是有别于逻辑“1” 与“0”的第三态。

说明: 1.同一规格铝芯导线载流量约为铜芯的０.7倍,选用铝芯导线可比铜芯导线大一个规格,交联聚乙烯绝缘可选用小一档规格，耐火电线电缆则应选较大规格。
2.本表计算容量是以三相380V、Ｃosφ=0.８5为基准，若单相２2０V、Cosφ＝0.8５,容量则应×1/3。
３.当环境温度较高或采用明敷方式等,其安全载流量都会下降,此时应选用较大规格;当用于頻繁起动电机时，应选用大２~３个规格。
４.本表聚氯乙烯绝缘电线按单根架空敷设方式计算,若为穿管或多根敷设，则应选用大2～3个规格。
5以上数据仅供参考,最终设计和确定电缆的型号和规格应参照有关专业资料或电工手册。
二、电线电缆的使用特性产品使用特性详见具体产品目录。
三、电线电缆的运输和保管⒈运输中严禁从高处扔下电缆或装有电缆的电缆盘，特别是在较低温度时(一般为５℃左右及以下)，扔、摔电缆将有可能导致绝缘、护套开裂。
⒉尽可能避免在露天以裸露方式存放电缆，电缆盘不允许平放。
⒊吊装包装件时，严禁几盘同时吊装。
在车辆、船舶等运输工具上，电缆盘要用合适方法加以固定，防止互相碰撞或翻倒，以防止机械损伤电缆。
⒋电缆严禁与酸、碱及矿物油类接触，要与这些有腐蚀性的物质隔离存放.贮存电缆的库房内不得有破坏绝缘及腐蚀金属的有害气体存在。
⒌电缆在保管期间，应定期滚动(夏季3个月一次，其他季节可酌情延期)。
滚动时，将向下存放盘边滚翻朝上，以免底面受潮腐烂。
存放时要经常注意电缆封头是否完好无损。
⒍电缆贮存期限以产品出厂期为限，一般不宜超过一年半,最长不超过二年。
四、电线电缆的安装与施工电线电缆敷设安装的设计和施工应按GＢ５0217-9４《电力工程电缆设计规范》等有关规定进行,并采用必要的电缆附件(终端和接头)。
供电系统运行质量、安全性和可靠性不仅与电线电缆本身质量有关，还与电缆附件和线路的施工质量有关。
通过对线路故障统计分析，由于施工、安装和接续等因素造成的故障往往要比电线电缆本体缺陷造成的故障可能性大得多。

一文知晓编码器信号电缆与传输抗干扰
一文知晓编码器信号电缆与传输抗干扰自动化行业里某些人对编码器的重视程度还很不够，更别说对一根编码器信号电缆了，“双绞屏蔽”“越粗越好”“接地接地再接地，看见空的就接地”看似有多简单?但这些模糊甚至有错误的对电缆的理解，问题是到了现场干扰的出现，往往就是从一根简单的电缆和接法就理解错了开始的。
其实编码器信号电缆技术含量颇高，其中包含了物理学基础和材料学知识等，越是基础的东西离物理学原理越近，需要理解原理结合基础原理和实验室试验及现场实践验证，而不再是只靠产品说明书手册了。
德国海德汉编码器对于信号电缆一直有严格指定的要求。
而我无法在这里一次给出标准答案，我没有足够的实验室条件，只有从电磁波信号原理推演。
只是依据十二年前向一家外企电缆厂家定制做过一根编码器电缆。
这家外企电缆厂原来就有电缆，但我按照对海德汉电缆的理解提出了针对编码器的专门定制要求，看中的是他们有实验室条件，可以测试和提供我要求的参数，实验参数固定化。
这根电缆我们已经用了12年，大大小小的项目也做了不少，也有很多知情的同行用过并得到了认可，而这家外企转向进入工控领域，做起了机器人电缆也很成功，。
所谓知己知彼百战不殆，在本文我们讨论的是：我们需要先了解编码器信号是什么样的信号，电缆有什么特性，干扰可能是从哪里来，才能根据现场错杂的干扰环境分析出对策。
我这里挑了行业里关于编码器信号电缆认识比较模糊甚至有些错误的问题，抛砖引玉提供业内真正是在现场实践者来参考与讨论，也欢迎留言争论。
一，编码器信号是什么?编码器信号有很多种类。
这里只讲用的最多的增量脉冲信号和数字串行信号（SSI 等信号）,电子开关频率800KHz以下的。
其他的总线信号的电缆、单电缆技术的电缆和工业以太网的电缆不在此文讨论。
（我也还没搞懂呢）这里讲的编码器信号是方波。
但是，电缆线的传导电特性是以电磁波的计算并设计的。
方波并不是单一频率的电磁波，按傅立叶分解，方波是有很多种频率的电磁波的叠加组合，下图演示的是方波最少有N=19个不同频率的电磁波合成的。

电哲线的接法 -回复
电哲线的接法-回复电哲线是一种电气接线方法，也被称为“哲学线”或“哲學電線”。
它源于对电流传输和电气传导理论的一种思考和实践，旨在优化电气设备的性能和效能。
电哲线接法有多种变种，本文将介绍其中一种主要的接法。
首先，我们需要明确电哲线的基本原理。
电哲线将电气设备的振动状态与电流传输的导线连接方式联系起来，以改善电气传导的效率。
振动状态是每个电气设备都会产生的，特别是在高负载和高电流传输时。
电哲线的目的是通过选择适当的导线连接方式来减少电流传导中的能量损失，提高电气设备的效能。
接下来，我们将介绍电哲线接法的具体步骤。
首先，选择合适的导线类型和规格。
一般来说，铜导线是最常用的导线材料，因为它具有良好的导电性能和机械强度。
根据电路负载或设备功率需求，选择合适的导线规格，以确保在电流传输过程中不会出现过载问题。
其次，根据实际情况确定导线的长度和布置方式。
导线的长度和布置方式会直接影响电流传输的效率和稳定性。
一般来说，导线越短，电流传输的损耗就越小。
因此，在实际布置中，尽量缩短导线的长度，减少电流传输的阻抗和能量损失。
接下来，选择合适的电哲线接法。
电哲线接法有多种变种，每种接法都有不同的优势和适用范围。
在这里，我们介绍一种常见的接法——星型接法。
在星型接法中，将电气设备的负载分别连接到导线的一个端点，然后将导线的另一个端点连接到电源的中性线上。
这样，电流就会从电源流过导线，同时也会在电气设备之间形成一个闭合的电流回路。
最后，进行接线测试和调试。
在完成电哲线接法后，需要进行一些测试和调试工作，以验证接线的正确性和稳定性。
可以使用合适的测试仪器和方法，检测电流传输的稳定性、电气设备的工作状态以及可能存在的问题。
根据测试结果，对接线进行必要的调整和修复，以确保电气设备的正常工作和性能。
综上所述，电哲线是一种优化电气设备性能和效能的电气接线方法。
其基本原理是通过选择合适的导线类型、规格和布置方式，减少电流传输过程中的能量损失。
SHF相位匹配电缆
特殊的微波系统需要相位匹配，使用稳相电缆。每个电缆组件将由设计师 修改到一个特殊的电器长度。诸如高功率放大器和多通道放大器的应用、多定向 天线系统、射频组合器、滤波器和相控阵雷达。
宇航级相位匹配电缆组件可增加空间有效载荷，使用宇航级 SHF 电缆和连 接器。 对于测试测量应用，稳相电缆的弯曲度是关键指标。
气密型。
我们的 SHF 电缆配套使用的连接器是最优的，并提供直头和弯头可选。大 多数连接器的界面都可使用在要求相位匹配的电缆组件上，例如 SMA, SMA 2.9 (K), TNC 18 和 N18。其他连接器类型如 BMA, SMP 和矩形、圆形多插针同 轴触点等连接器。

雷迪埃有能力制造成套相对相位匹配或对于一个标准，绝对相位匹配的电 缆组件。
相位跟踪
相位跟踪是多元相位匹配电缆组件的一项功能，当超过一个特定的温度范
围或弯曲范围亦或两者皆超过时，它能够互相复制相位特征。一旦安装完毕，相 位跟踪从本质上来说是对机械连贯性的度量。相位跟踪主要受 3 个参数影响。
· 电缆预处理：所有的雷迪埃 SHF 和半钢电缆在组装前都需要进行预处理。 · 温度范围：相位跟踪取决于系统温度的均匀性。 · 弯曲度：同轴电缆的弯曲度会直接影响相位的变化。

在要求相位匹配的电缆组件应用中，理想的情况是在成套的电缆中，每根 电缆必须与其他电缆具有相同的相位特征。由于电缆和连接器的制造、装配的内 在变化，我们提供了电气长度相位匹配公差和工作频率度相位匹配公差（±度/ 千兆赫）。相位匹配公差取决于：
· 工作频率：工作频率越高，两根电缆之间实现紧公差越困难 。 · 电缆组件长度：电缆组件越长，匹配任务越困难。 · 连接器界面和设计：紧公差，雷迪埃连接器是相位匹配设备的最优选择， 可提供坚固的电缆连接。 · 电缆材料和结构：速度系数是电缆的一个重要的参数，它取决于绝缘体结 构和密度。 · 温度 · 测试设备的精准性

想要获得最好的相位跟踪，需要做到两点：在安装电缆组件的过程中需要 额外的小心；所有的电缆需要以同种方式安装，并且在相同的热环境下。 产品特性
普遍用于相位匹配的雷迪埃 SHF 电缆已经列在下表中。“ProJack” 铠装可 选择 SHF5 和 SHF8，同时宇航等级也有部分可选。
电缆类型 SHF2.4 M
雷迪埃有能力制造成套相对相位匹配或对于一个标准，绝对相位匹配的电 缆组件。
相位跟踪
相位跟踪是多元相位匹配电缆组件的一项功能，当超过一个特定的温度范
围或弯曲范围亦或两者皆超过时，它能够互相复制相位特征。一旦安装完毕，相 位跟踪从本质上来说是对机械连贯性的度量。相位跟踪主要受 3 个参数影响。
· 电缆预处理：所有的雷迪埃 SHF 和半钢电缆在组装前都需要进行预处理。 · 温度范围：相位跟踪取决于系统温度的均匀性。 · 弯曲度：同轴电缆的弯曲度会直接影响相位的变化。
SHF 相位匹配电缆组件
什么是相位匹配 根据光的偏振态相位匹配可以分为两种类型。 角度相位匹配和温度相位匹配
电缆与连接器的最佳组合 独有的 SHF 电缆（低损耗电缆 low ultra loss cable）是可靠、稳定的
产品——精密电缆的设计和连接器界面坚固的连接方式，您可以放心地将它们使 用在相敏应用上。
同时 TestPro 电缆组件式具有高可靠性、高重复性的电缆组件。TestPro 可 使用在稳相测试台上，测试电缆相位稳定弯曲度的典型值为最大 2° 在 26.5 GHz 以及最大 5°在 40 GHz.。TestPro 电缆组件可与相位稳定电缆配对。
另外，推出一系列微波元器件（DC-18GHz），如移相器，SMA 和 N 型 连接器界面可选。
应用
特殊的微波系统需要相位匹配，使用稳相电缆。每个电缆组件将由设计师 修改到一个特殊的电器长度。诸如高功率放大器和多通道放大器的应用、多定向 天线系统、射频组合器、滤波器和相控阵雷达。
宇航级相位匹配电缆组件可增加空间有效载荷，使用宇航级 SHF 电缆和连 接器。 对于测试测量应用，稳相电缆的弯曲度是关键指标。
