TPS2000B系列在示波器中提供了独特的功能，其中包含您会熟悉且易于使用的控件和菜单。具有IsolatedChannel™技术的TPS2000B系列提供2通道或4通道版本，可提供接地隔离和通道之间的隔离，使您无需担心损坏电路即可进行测量。电池电源是标准配置，使其成为现场应用的自然选择。对于电力电子设备的工作，可选软件将常用的电力系统测量结果集成到仪器中，从而加快了电力分析和故障排除的速度。
进行浮动和差分测量–快速，准确，经济地
将被测电路意外接地是导致测量结果差和电路损坏的常见原因。连接两个或多个接地的探头可能会导致接地回路，如果电流过高，则可能导致组件和设备损坏。最重要的是，在没有合适的仪器和探头的情况下进行浮动测量会带来安全隐患。
泰克隔离通道技术简化了浮动测量。与以地面为参考的示波器不同，TPS2000B输入连接器壳体彼此隔离，并且与大地隔离。在规定的600 V RMS最大浮动电压范围内，IsolatedChannel技术可防止电流在TPS2000B输入BNC外壳之间或任何BNC外壳与地之间流动。
根据您的应用，可以使用不同的无源探头。使用随附的TPP0201无源探头，TPS2000B可以测量高达400 V p-p的电压。但是，为了达到TPP0201的安全等级，探头的参考引线必须相对于地面保持在30 V RMS之内。因此，TPP0201探头非常适合在最大电压不会超过30 V RMS的数字和模拟电路上工作。
在功率转换电子设备上进行的测量通常需要额定电压更高的探头。泰克提供两种带绝缘系统的无源探头，这些探头专门用于进行浮动测量。可选的P5122探头与TPS2000B结合使用时，适合在II类环境中的480 V RMS设备上进行测量，相对于大地的最大浮置电压高达600 V RMS。使用可选的P5120探头，TPS2000B可以测量高达800 V p-p的电压，最大浮动电压在600 V RMS地面范围内。使用可选的P5120探头，TPS2000B可以测量最高800 V p-p，最大浮动电压在600 V RMS之内地面。P5120是在高压直流电源上进行交流耦合纹波测量的最佳选择。
加快工业电源系统和电路的设计和测试的速度
从移动电话到工业电机驱动器，功率转换技术已在尺寸，性能和能效方面取得了显着进步。但是，即使是查看转换器输入和输出的最基本任务，也会因多个电压基准而变得复杂。多个参考也使同时查看来自控制电路和电源电路的信号变得很困难。在这些应用中使用以地面为参考的示波器，如果没有适当的差分探头，可能会损坏电路并产生不良的测量结果。为了调试电源转换电子设备，IsolatedChannel技术降低了损坏和意外电路交互的风险。
The TPS2000B Series offers a distinctive range of capabilities in an oscilloscope with controls and menus you will find familiar and easy to use. Available in 2- or 4-channel versions, the TPS2000B Series with IsolatedChannel™ technology provides isolation from ground and isolation between channels allowing you to take measurements with less worry about damaging circuitry. Battery power comes standard, making it a natural choice for field applications. For work on power electronics, optional software integrates commonly needed power system measurements into the instrument, speeding up power analysis and troubleshooting.
Make Floating and Differential Measurements – Quickly, Accurately, Affordably
Unintentionally grounding a circuit under test is a common cause of poor measurement results and circuit damage. Connecting two or more grounded probes can cause ground loops, and if the current is high enough can result in ruined components and equipment. Most importantly, taking floating measurements without the proper instruments and probes can pose a safety hazard.
Tektronix IsolatedChannel technology simplifies floating measurements. Unlike ground-referenced oscilloscopes, the TPS2000B input connector shells are isolated from each other and from earth ground. Within the specified 600 VRMS maximum float voltage, IsolatedChannel technology keeps current from flowing between the TPS2000B input BNC shells or from any BNC shell to earth.
Different passive probes are available, depending on your application. With the included TPP0201 passive probes, the TPS2000B can measure up to 400 Vp-p. However, to meet the safety rating of the TPP0201, the reference lead of the probe must be maintained within 30 VRMS relative to ground. Because of this, the TPP0201 probe is well suited for working on digital and analog circuits in which the maximum voltage never exceeds 30 VRMS.
Measurements on power conversion electronics usually require probes with higher voltage ratings. Tektronix offers two passive probes with insulation systems specifically designed for making floating measurements. Optional P5122 probes, when coupled with the TPS2000B, are suitable for making measurements on 480 VRMS devices in Category II environments, with a maximum float voltage of up to 600 VRMS relative to earth ground. With the optional P5120 probe the TPS2000B can measure up to 800 Vp-p, with a maximum float voltage within 600 VRMS of ground. With the optional P5120 probe the TPS2000B can measure up to 800 Vp-p with a maximum float voltage within 600 VRMS of ground. The P5120 is the best choice for making AC-coupled ripple measurements on high-voltage DC power supplies.
Speed the Design and Test of Industrial Power Systems and Circuits
From mobile phones to industrial motor drives, power conversion technology has enabled significant advances in size, performance, and energy efficiency. But even the most basic task of viewing a converter’s input and output is complicated by multiple voltage references. Multiple references also make it challenging to view signals from control circuits and power circuits at the same time. Using ground-referenced oscilloscopes in these applications, without appropriate differential probes, can damage circuits and produce bad measurements. For debugging power conversion electronics, IsolatedChannel technology reduces the risk of damage and unintended circuit interactions.
