Spectramag-6 Data Acquisition Unit
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 provide synchronous digitisation of the outputs from magnetic field
sensors, accelerometers, or acoustic sensors.
Features
• Can record data at rates up to 10kHz, combined with a PC via a USB interface
• Supplied software collects and displays data in both the time and frequency domain
to frequencies up to 5kHz
• Selectable AC and DC coupling, low-pass and FFT options available
• Battery or mains powered
Typical Applications
• Magnetic field and vibration surveys
• Pre-installation MRI/electron microscope site surveys

Data Acquisition Units
Mag-03DAM Data Acquisition Module
Designed to provide maximum resolution at low sampling frequencies, this portable,
high resolution six-channel 24-bit acquisition unit is for the long-term recording of
magnetic fields producing DC and low frequency signals, such as the Earth’s magnetic
field.
The Mag-03DAM connects and powers one or two magnetic field sensors. If only one
sensor is used, the other inputs can record analogue signals such as temperature.
Features
• Selectable sampling frequency, 16- or 24-bit A to D, and low-pass filter frequency
• Data sampling and storage is controlled by the user’s Windows® PC
• Acquired data is time-stamped and saved to disk
• Mains AC/DC adaptor supplied for battery charging, also enabling continuous
operation
Typical Application
• Earth magnetic field monitoring
