V14. Frequency characteristics [fc]
(1) Apply DC voltage to the external AGC IF AGC (pin 17) and vary it.
(2) SG1 : 45.75MHz continuous wave 10mVrms
SG2 : 45.65MHz to 39.75MHz continuous wave 2mVrms
Add the SG1 and SG2 signals using a T pat and adjust each SG signal level so that the above-mentioned levels are
reached and input the added signals to the VIF IN.
(3) First set the SG2 frequency to 45.65MHz, and then adjust the IF AGC voltage (V17) so that the output level at test
point A becomes 0.5Vp-p. V1
(4) Set the SG2 frequency to 39.75MHz and measure the output level. V2
(5) Calculate as follows :
fc = 20log
dB
V15. V16. Differential gain, differential phase [DG, DP]
(1) Internal AGC
(2) fp = 45.75MHz APL50% 87.5% Modulation video signal Vi = 10mVrms
(3) Measure the DG and DP at test point A.
V17. No-signal AFT voltage [V13]
(1) Internal AGC
(2) Measure the DC voltage at the AFT output (B).
V18. V19. V20. Maximum, minimum AFT output voltage, AFT detection sensitivity [V13H, V13L, Sf]
(1) Internal AGC
(2) fp = 45.75MHz
±1.5MHz, Sweep = 10mVrms (VIF input)
(3) Maximum voltage : V13H, minimum voltage : V13L.
(4) Measure the frequency deviation at which the voltage at test point B changes from V1 to V2.
f
V21. V22. VIF input resistance, Input capacitance [Ri, Ci]
(1) Referring to the Input Impedance Test Circuit, measure Ri and Ci with an impedance analyzer.
V2
V1
