产品概况Spirent Communications 公司的SmartBits 600B（SMB-600B）是业界中便携性能最强，最小巧的一种相对高端口密度的性能分析系统。

该系统与SMB-6000B 完全兼容，SMB-600B 最多支持两个模块，以及最多16 个10/100 Mbps以太网端口，4 个SmartMetrics™ 千兆以太网端口，4 个光纤通道端口，1 个10GbE 端口，或以上各种端口的组合。

如配置一块LAN－3101B（包含6个10/100M接口）和一块LAN－3320A（包含2个双介质10/100/1000M接口），或2块LAN－3101B板卡或2块LAN－3320A板卡。

SMB-600 可以串连在一起使用，从而获得更高的端口密度，使用户能够在质量控制和大容量生产环境中执行自动化的大规模测试。

通过使用SmartBits 多机扩展单元，还可将最多512 台机器同步连接起来。

用户可以通过一台PC 上的10/100 Mbps 以太网接口和基于Windows®的用户界面，非常轻松地对对SMB-600B 实施有效的控制。

SMB-600B 的设计用途包括：网络设备制造商：测试您的设备，然后还可以将网络设备和SMB-600B 携带到客户的地点，并现场展示您设备的性能。

评测实验室：测试和认证来自多个制造商的不同设备，并对其性能进行评测。

电信公司、ISP 和企业用户：对网络设备进行比较分析，在设备部署之前判定其的适用性。

In this situation, there is a time delay associated with the capacitance of the device and an overshoot condition associated with the inductance of the device and the inductance of the connection method. The capacitive effect is of minor importance in the parallel protection scheme because it only produces a time delay in the transition from the operating voltage to the clamp voltage as shown in Figure 5.The inductive effects in the device are due to actual turn-on time (time required for the device to go from zero current to full current) and lead inductance. This inductive effect produces an overshoot in the voltage across the equipment or component being protected as shown in Figure 6. Minimizing this overshoot is very important in the application, since the main purpose for adding a transient suppressor is to clamp voltage spikes. The SMB series have a very good response time, typically < 1 ns and negligible inductance. However, external inductive effects could produce unacceptable overshoot. Proper circuit layout,minimum lead lengths and placing the suppressor device as close as possible to the equipment or components to be protected will minimize this overshoot.Some input impedance represented by Z in is essential to prevent overstress of the protection device. This impedance should be as high as possible, without restricting the circuit operation.DUTY CYCLE DERATINGThe data of Figure 1 applies for non-repetitive conditions and at a lead temperature of 25°C. If the duty cycle increases, the peak power must be reduced as indicated by the curves of Figure 7. Average power must be derated as the lead or ambient temperature rises above 25°C. The average power derating curve normally given on data sheets may be normalized and used for this purpose.At first glance the derating curves of Figure 7 appear to be in error as the 10 ms pulse has a higher derating factor than the 10 m s pulse. However, when the derating factor for a given pulse of Figure 7 is multiplied by the peak power value of Figure 1 for the same pulse, the results follow the expected trend.VFigure 5.
