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 100 MHz and the ability to measure currents of up to 50 amps peak and 30 amps RMS with an accuracy of ±1%, these probes are ideal for analysing high frequency signals in areas such as power electronics, semiconductor development and avionics.
The CP series offers a dual measurement range that enables both small currents from 1 mA (in the 5A range) and larger currents up to 30 A RMS (in the 30A range) to be accurately measured. Thanks to the high sensitivity and excellent signal-to-noise ratio, even minor current fluctuations can be reliably detected. The integrated demagnetisation and auto-zero function ensures easy handling and precise measurements by automatically calibrating the system and eliminating interfering magnetisation.
The CP series probes are compact and ergonomically designed for easy one-handed operation. With their standard BNC interface, they are universally applicable and can be connected to any oscilloscope. The CP series has an overload protection function that ensures fast and precise acquisition of signal peaks and is equipped with an overcurrent alarm that is activated when the permissible current limit is exceeded.
The CP series has a wide range of applications, including the development of power electronics for electric vehicles, the design of switching power supplies, the development of transformers and inverters, 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 precisely measuring and analysing high-frequency AC/DC currents in demanding technical applications.
