Notes:
1. The accelerometer analog voltage outputs are the raw sensor output.
These outputs are taken from the output of the accelerometers.
2. The rate sensor analog voltage outputs are scaled to represent °/s. These
outputs are created by a D/A converter.
3. Actual output depends on DMU measurement mode. These outputs are
created by a D/A converter.
All analog outputs are fully buffered and are designed to interface directly
to data acquisition equipment.
