Differential Current Measurements差动测量

Most true-differential voltage amplifiers have a maximum bandwidth of about 100 MHz. 大多数true-differential电压放大器有zui大带宽约100赫兹。The CT1 or CT6 can make differential current measurements to 1 GHz and 2 GHz, respectively, by passing two wires carrying opposing currents through the same core. 这可以使差或CT6 CT1电流测量到1兆赫和2兆赫,分别通过两线电流,同时通过携带对方核心。The displayed result is the difference current. 结果所显示的是截然不同的电流。The CT2 can perform the same function to 200 MHz.CT2可以执行同样的功能到200兆赫。

In all cases, Derating with Frequency and Amp-second Product (Current-time Product) guidelines should not be exceeded. 在所有病例中,Derating与频率和Amp-second产品(Current-time产品规范不应超过。(See Characteristics.)(见特点。)

Single-shot and Low Rep-rate Pulse Measurements台和低Rep-rate脉冲测量

These common measurements are easy to make with the CT1, CT2, or CT6 provided that your signal fits within the Max Pulse Current and Amp-second Product (Current-time Product) guidelines for the specific current probe characteristics.这些通用的测量是容易与CT1,CT2或CT6规定好了,如果你适合在zui大信号脉冲电流和Amp-second产品(Current-time产品关于特定的电流探测器的特点。

For example, the CT2 is rated at 36 A peak, with an Amp-second Product of 50 × 10-6 seconds (50 Amp-microseconds), therefore the CT2 can safely handle a 36 A peak pulse with a maximum width of 1.39 microseconds or lower amplitude pulses for longer pulse widths. 例如,CT2被36岁的高潮,和一个Amp-second 50×产品时刻秒(50 Amp-microseconds),所以CT2可以安全地处理36峰与zui大宽度脉冲的振幅1.39微秒脉冲或降低长脉冲宽度。The CT1, CT2, and CT6 all have low-frequency roll-off characteristics. 这个CT1,CT2,CT6同时减少伴侣翻身时都有低频特性。Low-frequency "droop" will exhibit itself when the pulse width approaches the L/R time constant of the specific transformer.“下垂”将展示低频脉冲宽度的方法本身,L / R时间常数的特定的变压器。

Propagation Delay Measurements传播延迟测量

Two CT1 or CT2 Current Transformers with matching probe cables can be used to measure propagation delay (transit time) between the input and output currents of high-frequency devices. 两个CT1或CT2电流互感器与之相配套的探测器可以用来测量电缆传输延迟(如时间)的输入、输出电流之间的高频设备。The probe outputs are connected to the inputs of dual-channel real-time or sampling scopes.探测器的输出连接到的输入dual-channel实时或抽样范围。

Verification of any Probe/Cable/Scope System mismatch can be obtained by passing the same signal current through both probes and observing total system delay difference, if any.任何探测器检定/电缆/范围系统不匹配可以通过经过同一信号电流进行了探索和观察,经过两个整个系统的时滞差分(如果有的话)。
