PFM3000 3GHz High-Resolution Frequency Counter, 3Hz–3GHz, 8.5-Digit Display

The PFM3000 is a handheld frequency counter designed for professionals requiring precise frequency measurements across a wide range. Its capability to measure from 3 Hz up to 3 GHz makes it suitable for various applications, from audio frequencies to microwave signals. The device's high input sensitivity ensures accurate readings even at low signal levels, and its high impedance measurement up to 125 MHz allows for minimal signal interference. Employing a reciprocal counting technique, the PFM3000 offers high-resolution measurements with rapid updates, making it efficient for real-time analysis. The period measurement function further extends its utility, allowing users to measure time intervals with high precision. The large 8.5-digit LCD provides clear and comprehensive information, including measurement functions, time, overflow indicators, trigger activity, low battery alerts, and measurement units. This combination of features makes the PFM3000 a versatile and reliable tool for technicians and engineers working in various fields. ​
