1. Filtering:
Signals can be filtered (using low and high pass filters) to remove unwanted
frequencies.
2. Offset:
In the second stage, a DC offset voltage can be added to or subtracted from the
magnetometer output signal, producing a DC adjusted output.
3. Gain:
Finally, the DC adjusted output signal can be amplified by a variable gain stage, to
produce the conditioned output signal.
Offset and gain are controlled independently for the X, Y and Z channels, but the filter settings
are common to all three.
The conditioned output signals and the original magnetometer (unconditioned) output signals
are available as analogue voltages from the SCU1. In addition, the DC components of each
conditioned signal are displayed digitally on display meters.
