The CT1 and CT2 Current Probes are designed for permanent or semi-permanent in-circuit installation. CT2 CT1電流探頭的設計和*性或半*在線安裝。Each probe consists of a current transformer and an interconnecting cable. 每種探由電流互感器和互連電纜。The current transformers have a small hole through which a current carrying conductor is passed during circuit assembly.目前有一個小洞變壓器電流通過其導體電路中通過進行組裝。
The P6041 Probe Cable provides the connection between the CT1 and CT2 Current Transformers and a BNC oscilloscope input. P6041探測器提供的電纜之間的連接和CT2 CT1電流互感器和一個BNC示波器輸入。A 50 Ω termination is required to terminate the cable when connected to a high-impedance （1 MΩ） oscilloscope input. 一個50Ω終止時需要終止電纜連接到一個高祖抗（1 MΩ）示波器輸入。One probe cable can be used to monitor several current transformers that have been wired into a circuit.一個探針電纜可用來監控,幾個電流互感器接線進入一個電路。
The CT1 and CT2 detachable cable design enables one or more probes to be located on circuit boards or in other limited space areas.CT2 CT1電纜的設計使得毛皮和一個或多個探針位于電路板或其他有限的空間區域。
The CT6 offers the smallest form factor available, for measurement on ever-shrinking circuit boards and components. 提供zui小的CT6形式因素可能了,因為ever-shrinking電路板測試和部件。It is designed for temporary installation and does not incorporate removable cables, as the CT1 and CT2 do.它是專為臨時安裝,沒有納入移動電纜,和CT2 CT1。
Specified rise time and bandwidth are obtained when using the probe cables provided: The P6041 cable used with the CT1 and CT2 is 42 inches nominal. 的上升時間和帶寬得到了電纜使用探測器提供:P6041電纜用CT1 42英寸和CT2是有名無實。If additional length is required, the cables can be extended by using high-quality 50 Ω cable and suitable interface connectors. 如果附加長度時,電纜可以延長采用優質50Ω電纜和合適的接口連接器。（Also see Special Probe Cables, Optional Accessories.） （也看到特別的探針,可選配件電纜。）Long cables may degrade high-frequency response.根長電纜可以降級頻率響應。
The CT1 and CT6 provide an output of 5 mV for each milliamp of input current when terminated in 50 Ω. 提供了一種輸出和CT6 CT1 5 mV為每個milliamp時的輸入電流在50Ω終止。The CT2 provides 1 mV per milliamp when terminated in 50 Ω.CT2提供的每milliamp 1 mV 50Ω當終止。
The CT1, CT2, and CT6 high-frequency current transformers are dynamic （i.e., non-DC） current measuring devices. 這個CT1,CT2,CT6高頻電流互感器是一種動態的（例如,non-DC電流測量設備。They are typically used in conjunction with compatible high-bandwidth oscilloscopes and other instruments to observe and/or record high-frequency current waveforms. 他們通?？梢耘浜霞嫒莸母邘捠静ㄆ骱推渌麅x器觀察和/或記錄高頻電流波形。The CT1, CT2, and CT6 normally operate directly into 50 Ω scopes and other measuring device inputs.這個CT1,CT2,CT6運作正常直接進入50Ω范圍和其他測量設備的投入。
The CT1 or CT2 can be used with 1 MΩ input systems; use the P6041 probe cable and terminate the output with a 50 Ω feed-through termination （see Optional Accessories）.這CT2 CT1或可以使用1 MΩ輸入系統,使用P6041探測器輸出電纜和終止一個50Ωfeed-through終止（見可選配件）。
In all cases, the CT1, CT2, and CT6 must work into 50 Ωs to obtain specified performance and sensitivity.在所有情況下,CT1,CT2,CT6必須工作到50個Ωs得到規定的性能和靈敏度。
Most true-differential voltage amplifiers have a maximum bandwidth of about 100 MHz. 大多數true-differential電壓放大器有zui大帶寬約100赫茲。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. 這可以使差或CT6 CT1電流測量到1兆赫和2兆赫,分別通過兩線電流,同時通過攜帶對方核心。The displayed result is the difference current. 結果所顯示的是截然不同的電流。The CT2 can perform the same function to 200 MHz.CT2可以執行同樣的功能到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與頻率和Amp-second產品（Current-time產品規范不應超過。（See Characteristics.）（見特點。）
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.這些通用的測量是容易與CT1,CT2或CT6規定好了,如果你適合在zui大信號脈沖電流和Amp-second產品（Current-time產品關于特定的電流探測器的特點。
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歲的高潮,和一個Amp-second 50×產品時刻秒（50 Amp-microseconds）,所以CT2可以安全地處理36峰與zui大寬度脈沖的振幅1.39微秒脈沖或降低長脈沖寬度。The CT1, CT2, and CT6 all have low-frequency roll-off characteristics. 這個CT1,CT2,CT6同時減少伴侶翻身時都有低頻特性。Low-frequency "droop" will exhibit itself when the pulse width approaches the L/R time constant of the specific transformer.“下垂”將展示低頻脈沖寬度的方法本身,L / R時間常數的特定的變壓器。
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. 兩個CT1或CT2電流互感器與之相配套的探測器可以用來測量電纜傳輸延遲（如時間）的輸入、輸出電流之間的高頻設備。The probe outputs are connected to the inputs of dual-channel real-time or sampling scopes.探測器的輸出連接到的輸入dual-channel實時或抽樣范圍。
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.任何探測器檢定/電纜/范圍系統不匹配可以通過經過同一信號電流進行了探索和觀察,經過兩個整個系統的時滯差分（如果有的話）。
