CP High-Frequency Probe Series
The Micsig CP series is a range of high-frequency AC/DC current probes designed for precise measurements of small to medium currents in demanding electronic applications. With a bandwidth of up to 150 MHz and the ability to measure currents up to 50 amps peak and 30 amps RMS with an accuracy of ±1%, these probes are ideal for analyzing high-frequency signals in fields such as power electronics, semiconductor development, and avionics.
The CP series offers a dual measuring range, enabling the accurate detection of both small currents from 1 mA (in the 5 A range) to 10 mA RMS (in the 30 A range). Thanks to its high sensitivity and excellent signal-to-noise ratio, even minute current fluctuations can be reliably detected. The integrated demagnetization and auto-zero function ensures ease of use and precise measurements by automatically calibrating the system and eliminating interfering magnetization.
The CP series probes are compact and ergonomically designed, allowing for easy one-handed operation. With their standard BNC interface, they are universally compatible and can be connected to any oscilloscope. The CP series features overload protection, ensuring fast and accurate capture of signal spikes, and is equipped with an overcurrent alarm that activates when the permissible current limit is exceeded.
The CP series offers a wide range of applications, including the development of power electronics for electric vehicles, the design of switched-mode power supplies, the development of transformers and inverters, as well as the testing of semiconductor components and the control of industrial and consumer electronic devices.
In summary, the Micsig CP series offers a powerful and flexible solution for the precise acquisition and analysis of high-frequency AC/DC currents in demanding technical applications.
