V11. C/S beat [Ics]
V12.V13. Differential gain, differential phase [DG, DP]
V14.V15. Black noise threshold and clamp voltage [V BTH , V BCL ]
V16. V17. VIF input resistance, input capacitance [R i , C i ]
(1) Apply DC voltage to the external AGC IF AGC (pin 18) and vary it.
(2) fp = 38.9MHz CW;10mVrms
(3) Adjust the IF AGC (pin 18) voltage so that the output level at test point A becomes 1.3Vp-p.
(4) Measure the difference between the levels for 4.43MHz and 1.07MHz components at test point A.
(1) Internal AGC
(2) fp = 38.9MHz APL50% 87.5% Modulation video signal
(3) Measure the DG and DP at test point A.
(1) Apply DC voltage (1 to 3V) to the external AGC, IF AGC (pin 18) and adjust the voltage.
(2) fp = 38.9MHz 400Hz 40% AM 10mVrms (VIF input)
(3) Adjust the IF AGC (pin 18) voltage to operate the noise canceller.
(1) External AGC (V 18 = 2V)
(2) Referring to the Input Impedance Test Circuit, measure R i and C i with an impedance analyzer.
Measure the V BTH , V BCL at test point A.
fc = 34.47MHz CW;10mVrms − 10dB
