— DC to 1.6MHz Bandwidth, Analog BNC Output, and Adjustable Signal Conditioning for High-Frequency Magnetic Field Measurement

ZHANGJIAGANG, China, July 14, 2026 /PRNewswire/ -- MultiDimension Technology Co., Ltd. (MDT), a leading supplier of magnetic sensors and a pioneer in Tunneling Magnetoresistance (TMR) technology, today introduced the HFM2905 high-frequency magnetic field probe. Complementing MDT's USB magnetometer series optimized for low-frequency magnetic field measurements, the HFM2905 enables real-time observation and analysis of high-frequency magnetic signals. Combining wide bandwidth, analog output, and integrated signal conditioning in a compact USB-powered instrument, it provides an ideal measurement solution for electronics R&D, laboratory research, and industrial testing.

Unlike conventional low-frequency magnetometers, the HFM2905 accurately measures magnetic field signals from DC to 1.6MHz, enabling engineers to capture fast-changing magnetic field waveforms that are difficult to observe using traditional magnetic measurement instruments. The probe features a standard BNC analog output, allowing direct connection to an oscilloscope or data acquisition (DAQ) system for real-time analysis of magnetic field waveforms, frequency, and amplitude.The HFM2905 highlights the unique advantages of MDT's TMR magnetic sensing technology by combining wide measurement bandwidth with high sensitivity to low-level magnetic fields, enabling accurate real-time analysis of fast-changing magnetic signals.The HFM2905 integrates selectable gain and low-pass filter settings to optimize measurements across a wide range of signal amplitudes and frequencies. Powered directly from a standard USB port, the probe requires no external power supply for fast and convenient setup. A dedicated calibration fixture with an integrated precision stripline and current transformer (CT) enables on-site calibration to maintain measurement accuracy and traceability.The HFM2905 is ideal for switching power supply design, power electronics development, motor drive analysis, transformer and inductor characterization, EMI/EMC debugging, wireless power transfer research, automatic test equipment, laboratory research, university education, and other applications requiring real-time high-frequency magnetic field measurement.Key Features
