能量分散谱仪(EDS)
能谱仪的缺点：
• (1)能量分辨率低，峰背比低。由于能谱仪的探头直 接对着样品，所以由背散射电子或X射线所激发产 生的荧光X射线信号也被同时检测到，从而使得Si(Li) 检测器检测到的特征谱线在强度提高的同时，背底 也相应提高，谱线的重叠现象严重。故仪器分辨不 同能量特征X射线的能力变差。能谱仪的能量分辨 率(130eV)比波谱仪的能量分辨率(5eV)低。 • (2)工作条件要求严格。Si(Li)探头必须始终保持在液 氦冷却的低温状态，即使是在不工作时也不能中断， 否则晶体内Li的浓度分布状态就会因扩散而变化， 导致探头功能下降甚至完全被破坏。

能谱仪
• 能谱仪全称为能量分散谱仪(EDS)． • 能谱仪的结构及工作原理： • 能谱仪是利用X 光量子的能量不同来进行元素分析的方 法，对于某一种元素的X 光量子从主量子数为n1的层上 跃迁到主量子数为n2的层上时有特定的能量ΔE＝En1－ En2。X 光量子的数目是作为测量样品中某元素的相对 百分含量用，即不同的X 光量子在多道分析器的不同道 址出现，而脉冲数－脉冲高度曲线在荧光屏或打印机上 显示出来，这就是X光量子的能谱曲线。 • 所谓能谱仪实际上是一些电子仪器，主要单元是半导体 探测器（一般称探头）和多道脉冲高度分析器，用以将 X光量子按能量展谱。

Screw holes for panelmounting kit15.DIN-rail mounting kitMounting DimensionsUnit = mm (inch)DIN-Rail MountingThe aluminum DIN-rail attachment plate should already be fixed to the back panel of the EDS when you take it out of the box. If you need to reattach the DIN-rail attachment plate, make sure the stiff metal spring is situated towards the top, as shown in the figures below. STEP 1: Insert the top of the DIN-rail into the slot just below the stiff metal spring.STEP 2: The DIN-Rail attachment unit will snap into place as shown below.To remove the EDS from the DIN-rail, simply reverse Steps 1 and 2 above.Wall Mounting (optional)For some applications, you will find it convenient to mount the EDS-G205A-4PoE on a wall, as shown in the following figures. STEP 1:Remove the aluminum DIN-rail attachment plate from the EDS-G205A-4PoE’s rear panel, and then attach the wall mount plates as shown in the diagram at the right.STEP 2:Mounting the EDS-G205A-4PoE on the wall requires 4 screws and the recommended tightening torque is 3.5±0.5 (kgf cm). Use the switch, with wall mount plates attached, as a guide to mark the correct locations of the 4 screws. The heads of the screws should be less than 6.0 mm in diameter, and the shafts should be less than 3.5 mm in diameter, as shown in the figure at the right.NOTE Before tightening the screws into the wall, make sure the screwhead and shank size are suitable by inserting the screw into one of the keyhole-shaped apertures of the wall mounting plates. Do not screw the screws in completely—leave about 2 mm to allow room for sliding the wall mount panel between the wall and the screwsSTEP 3: Array Once the screws are fixed on thewall, insert the four screw headsthrough the large parts of thekeyhole-shaped apertures, and thenslide the EDS downwards, asindicated. Tighten the four screwsfor added stability.Wiring RequirementsYou should also pay attention to the following points:•Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must cross, make sure the wires are perpendicular at the intersection point.NOTE: Do not run signal or communications wiring and power wiring in the same wire conduit. To avoid interference, wires with different signal characteristics should be routed separately.•You can use the type of signal transmitted through a wire to determine which wires should be kept separate. The rule of thumb is that wiring that shares similar electrical characteristics can bebundled together.•Keep input wiring and output wiring separated.•It is strongly advised that you label wiring to all devices in the system when necessary.•Please use copper conductor only.Grounding the EtherDevice SwitchGrounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI). Run the ground connection from the ground screw to the grounding surface prior to connecting devices.Wiring the Redundant Power InputsThe two 2-contact terminal block connectors on the EDS’s top panel are used for the EDS’s two DC power inputs. Top and front views of the terminal block connectors are shown here.STEP 1: Array Insert the negative/positive DC wires into the V-/V+terminals.STEP 2:To keep the DC wires from pulling loose, use a smallflat-blade screwdriver to tighten the wire-clamp screws onthe front of the terminal block connector.STEP 3:Insert the plastic terminal block connector prongs into theterminal block receptor, which is located on the EDS’s toppanel.Communication ConnectionsThe EDS-G205A-4PoE switches have 4 10/100/1000Base-T(X) PoEEthernet ports for connecting PoE devices, and 1 10/100/1000BaseT portor 1 100/1000BaseX SFP slot for uplink connection. For fiber connections,a field installed optical transceiver must be UL Recognized, in the Class Icategory, and contain the following CDRH Certification Marking:‘Complies with 21CFR 1040.10 and 1040.11’.10/100/1000BaseT(X) Ethernet Port Connection10/100/1000BaseT(X) ports located on the EDS’s front panel are used toconnect to Ethernet-enabled devices. Below we show pinouts for bothMDI (NIC-type) ports and MDI-X (HUB/switch-type) ports, and also showcable wiring diagrams for straight-through and cross-over Ethernet cables.10/100BaseT(x) RJ45 PinoutsMDI Port Pinouts MDI-X Port Pinouts 8-pin RJ45Pin Signal 1 Tx+ 2 Tx- 3 Rx+ 6Rx-Pin Signal 1 Rx+ 2 Rx- 3 Tx+ 6Tx-1000BaseT RJ45 PinoutsPin MDI MDI-X 1 BI_DA+ BI_DB+ 2 BI_DA- BI_DB- 3 BI_DB+ BI_DA+ 4 BI_DC+ BI_DD+ 5 BI_DC- BI_DD- 6 BI_DB-BI_DA-7 BI_DD+BI_DC+ 8BI_DD- BI_DC-PoE Ethernet Port ConnectionPoE ports located on the EDS switch’s front panel are used to connect to PoE-enabled devices.

However, some PDs only support MDI mode or MDI-X mode only. The following figures show how to select the correct cable to connect between the PD and EDS-G205A-4PoE.RJ45 (8-pin) to RJ45 (8-pin) Straight-Through Cable WiringRJ45 (8-pin) to RJ45 (8-pin) Cross-Over Cable WiringNOTE If the PD only supports PoE MDI mode (V+, V+, V-, V- for pins 1, 2, 3, 6), choose a cross-over Ethernet cable to connect the PD and the EDS switch. If the PD only supports PoE MDI-X mode (V-, V-, V+, V+ for pins 1, 2, 3, 6), choose a straight-through Ethernet cable between the PD and the EDS switch.Redundant Power InputsBoth power inputs can be connected simultaneously to live DC power sources. If one power source fails, the other live source acts as a backup, and automatically supplies all of the EDS’s power needs.DIP Switch SettingsThe default setting for each DIP Switch is OFF. The following table explains the effect of setting the DIP Switches to the ON positions.EDS-G205A-4PoE (Copper Model)EDS-G205A-4PoE-1GSFP(SFP Model)DIP SwitchSetting DescriptionBSPONEnable broadcast storm protection OFF Disable broadcast storm protection Jumbo FrameONEnable jumbo frame function OFF Disable jumbo frame function802.3azONEnable the energy-efficient Ethernet function OFF Disable the energy-efficient Ethernet function PoE High Power ON Supports PoE high power output up to 36 W.

This means that you can use either a straight-through cable or cross-over cable to connect the EDS to Ethernet devices.Triple Speed Functionality and SwitchingThe Moxa EtherDevice Switch’s 10/100/1000 Mbps switched RJ45 port auto negotiates with the connected device for the fastest data transmission rate supported by both devices. All models of Moxa EtherDevice Switch are plug-and-play devices, so that software configuration is not required at installation, or during maintenance. The half/full duplex mode for the switched RJ45 ports is user dependent and changes (by auto-negotiation) to full or half duplex, depending on which transmission speed is supported by the attached device.Jumbo FrameThe EDS-G205A-4PoE series supports Ethernet jumbo frames up to 10k, which is with more than 1500 bytes of payload. This function is by default disabled and can be enabled by turning on the DIP switch labeled “Jumbo” on the top cover. This is commonly used for large packet size applications such as video surveillance.Broadcast Storm ProtectionThe EDS-G205A-4PoE Series has a built-in algorithm for limiting the amount of broadcast packets through the switch. This function is by default disabled and can be enabled by turning on the DIP switch labeled “BSP” on the top cover. If the broadcast storm protection algorithm detects more than 2k broadcast frames per second, then the switch will be suppressed from receiving broadcast frames for a period of 2 ms to prevent any further flooding.Total Power BudgetFor the total power budget, the EDS-G205A-4PoE will provide 62 W at 12 to 17 VDC input, 120 W at 18 to 35 VDC input, and 144 W at 36 to 57 VDC input. The total power budget is the total amount of reserved PoE power based on the PoE class of the PoE device. If a newly connected PoE device causes the total reserved power to exceed the total power budget, the newly connected PoE device will be denied power.Input Voltage Total Power Budget12 VDC (12 to 17 VDC) 62 W24 VDC (18 to 35 VDC) 120 W48 VDC (36 to 57 VDC) 144 WPoE Class Reserved Power0 15.4 W1 4.0 W2 7.0 W3 15.4 W4 30 WPoE High Power ApplicationPoE High Power can be enabled by DIP switch, and supply up to 36 W of PoE power when the PSE detects an 802.3af or 802.3at connection.
