hand side of this image) which allows access to the baseband, giving
you direct access to the output of the DACs (and input to the ADCs).
The "Baseband Expansion Board" would be plugged in to that header to
allow signals to be used without passing through the analogue
front-end.  The expansion board would be used to mix the I and Q
signals (and possibly offer some other features).
