Notes to the characteristics
1. Pin 11 has a double function. When during switch-on a current of 9 mA is supplied to this pin, it is used to start the
2. On set AGC.
3. The input impedance has been chosen such that a SAW filter can be employed.
4. Measured with 0 dB = 450 V.
5. Measured at 10 mV RMS top sync input signal.
6. Projected zero point; i.e. with switched demodulator.
7. White 10% of the top sync amplitude.
8. Measured according to the test line illustrated by Fig.2. The differential gain is expressed as a percentage of the
9. This figure is valid for the complete video signal amplitude (peak white-to-black); see Fig.3. The non linearity is

10. The test set up and input conditions are illustrated by Fig.4. The figures are measured at an input signal of 10 mV
11. Measured with a source impedance of 75
12. The sound circuit is measured (unless otherwise specified) with an input signal of V

level. The differential phase is defined as the difference in degrees between the largest and smallest phase angle.
The differential gain and phase are measured with a DSB signal.
