Notes
1. On set AGC.
2. This parameter is not tested during production and is just given as application information for the designer of the
3. Loop bandwidth B
4. This parameter is not tested during production but is guaranteed by the design and qualified by means of matrix
5. Measured at 10 mV (RMS) top sync input signal.
6. So called projected zero point, i.e. with switched demodulator.
