3. Connect an RF generator to the FM input SMA connector J28 or J26 using an SMA cable.
4. Connect an audio analyzer to the S/PDIF output connector, J30, using an optical cable.

To avoid possible sources of interference, please remove C9 or C12 (depending on the daughtercard). This will
disconnect the headphone circuit from the test circuit.
