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. Measured at 10 mV (RMS) top sync input signal.
4. So called projected zero point, i.e. with switched demodulator.
5. Measured in accordance with the test line given in Fig.10. For the differential phase test the peak white setting is
6. This parameter is not tested during production but is guaranteed by the design and qualified by means of matrix
7. This figure is valid for the complete video signal amplitude (peak white-to-black), see Fig.11.
8. The test set-up and input conditions are given in Fig.12. The figures are measured with an input signal of
9. Measured with a source impedance of 75 , where:
10. To obtain a good noise immunity of the AGC circuit the AGC detector is gated during the sync pulse. This gating is
