This portable six-channel 24-bit data acquisition unit is designed for simultaneous collection and analysis of magnetic field, vibration and acoustic data in three axes. The six input channels on the Spectramag-6 provide synchronous digitisation of the outputs from magnetic field sensors and accelerometers, or if required acoustic sensors.
Combined with a PC via a USB interface, the unit can record data at rates up to 10kHz. The supplied software collects and displays data in both the time and frequency domain to frequencies up to 3.5kHz, with a range of filtering and FFT options available.
