All input signals are measured r.m.s. at top sync and 38,9 MHz.
Measured with 0 dB = 200
μ
V.
Tuner AGC starting point is defined as ‘level of input signal when tuner AGC current = 1 mA’.
Measured with pin 3 connected via 39 k
resistor to V
CC
(pin 11), with an r.m.s. voltage of 10 mV top sync input
signal and with pin 12 not loaded.
At the ‘projected zero point’, e.g. with switched demodulator.
Measured in the circuit of Fig.7:
the differential gain is expressed as a percentage of the difference in peak amplitudes between the largest and
smallest value relative to the subcarrier amplitude at blanking level;
the differential phase is defined as ‘the difference (in degrees) between the largest and smallest phase angles’.
Measured according to the test line shown in Fig.9:
the non-linearity is expressed as a percentage of the maximum deviation of a luminance step from the mean step,
with respect to the mean step;
the mean step is (white level
black level) divided by the number of steps.
Measured up to 45 dB gain control.
Test set-up and input conditions for intermodulation measurements as in Figs 6 and 7.
