This is a small tool for gathering and evaluating more reception-related data
from the dib3000-demodulators, than the DVB-API currently makes use of.

It uses the i2c-dev-interface. In order to use it, you have to enable i2c-dev
in your kernel.  The module i2c-dev is loaded automatically, when you want to
access the /dev/i2c-*-node.

If your distribution hasn't create the /dev/i2c-*-nodes you can use the
make-i2c-dev-script located its source directory.

It is not yet completed, but works fine for all dib3000mb-demods (all of the
USB1.1 dibusb-devices are equipped with it).
Having a CSV output would certainly be useful, when you want to make range
tests by driving around with your car and check the signal. Nevertheless,
this isn't written yet, but should be easy-going. Each line then should
have an timestamp.

I cannot guarantee for the values this program calculates, I'm not a signal
expert, thus I don't know if they are correct.

Thanks to Amaury Demol from DiBcom, who provides source for showing me how to
calculate frequencies from the demod values.
