6. Conditioned Outputs.
These three BNC connectors carry the conditioned analogue output
voltages. The conditioned outputs are the magnetometer X, Y and Z signals after they have
been modified by the filter, gain and offset controls.

7. Low Pass Filter (LPF) Control.
The SCU1 applies low pass filtering to the magnetometer
output signals. This control sets the -3dB point frequency for the LPF.
Note:
The LPF cannot be completely disabled.
8. High Pass Filter (HPF) Control
. The SCU1 can apply high pass filtering to the magnetometer
output signals. This control sets the -3dB point frequency for the HPF.
9. Magnetometer Supply Voltage Control.
This control sets the voltage that the SCU1 supplies
to the magnetometer connector power pins. This enables the user to vary the voltage
to compensate for cable voltage loss, ensuring the required voltage is present at the
magnetometer. See
for guidance on matching voltage to cable
length.
10. Display Panel Meters.
The conditioned output voltages for the three channels are displayed
numerically on these 3½ digit meters. The meters display in volts and should only be used for
low frequency signals. See
for full details on how to use the meters.
