Description | |
The HFM2905 is a single-axis, analog, high-frequency magnetometer that measures magnetic-field signals aligned with the probe axis. It covers DC to 1.6 MHz magnetic-field bandwidth and supports AC field amplitudes from 0.1 Gs to 2 Gs. To simplify bench characterization, HFM2905 combines the magnetic sensor, on-board signal conditioning, USB +5V power input, and a BNC analog voltage output. The BNC interface is intended for direct connection to an oscilloscope or DAQ, enabling immediate visualization of the output waveform and straightforward extraction of magnetic-field amplitude and frequency. |  HFM2905 |
