Note 6: Intermodulation
Input following composite signals to be PIF input.
(1) SG : 1 58.75 MHz, 84 dBV
(2) SG : 2 54.25 MHz, 74 dBV
(3) SG : 3 55.17 MHz, 74 dBV
Supply DC voltage to 2nd AGC terminal from external source, so that bottom of output signal voltage
matches sync. tip level. Measure the difference of output signal voltage at pin 40 between 3.58 MHz
component (chroma) and 920 kHz component.
Note 7: Suppression of picture career
PIF input : fp = 58.75 MHz, fm = 15.7 kHz, 78%AM, 84 dBV
Measure the difference of output signal voltage at pin 40 between 15.7 kHz component (video) and 58.75
MHz component (career).
Note 8: Suppression of picture career harmonics
PIF input : fp = 58.75 MHz, fm = 15.7 kHz, 78%AM, 84 dBV
Measure the difference of output signal voltage at pin 40 between 15.7 kHz component (video) and 117.5
MHz component (2nd harmonics).
Note 9: Differential gain / Differential phase
PIF input : fp = 58.75 MHz, standard television signal (V / S = 10 : 4 ramp waveform), 87.5%AM, 84 dBV
Measure differential gain and differential phase.
Note 10: Sync voltage level
PIF input : fp = 58.75 MHz, standard television signal (V / S = 10 : 4 ramp waveform), 87.5%AM, 84 dBV
Measure sync tip voltage level.
Note 11: AFT control steepness
PIF input : fp = 58.75 MHz, 84 dBV, CW
Measure AFT output voltage. (VAFT1) Raise input frequency by 20 kHz, measure AFT output voltage
(VAFT2). AFT control steepness is calculated by following equality.
AFT control steepness = f / V = 20 / V [ kHz / V]
Note 12: AFT mute voltage
PIF : non input
SW1 : GND, 2nd AGC : GND
Measure AFT output voltage.
Note 13: RF AGC maximum output voltage / minimum output voltage
(1) RF AGC maximum output voltage
PIF input : fp = 58.75 MHz, fm = 15.7 kHz, 30%AM, 20 dBV
Measure RF AFT output voltage.
(2) RF AGC minimum output voltage
PIF input : fp = 58.75 MHz, fm = 15.7 kHz, 30%AM, 100 dBV
Measure RF AFT output voltage.
Note 14: Black & white noise inverter level and clamp level
PIF input : fp = 57~65 MHz, 84 dBV
Supply DC voltage to 2nd AGC from external source, sweep input frequency.
<Converter circuit>
Note 15: Conversion gain
SIF input : fs = 54.25 MHz, 80 dBV
Measure 10.7 MHz (2nd SIF) component of output signal voltage at pin 8.
CG = [10.7 MHz level]80 dBV
Note 16: 2nd SIF maximum output
SIF input : fs = 54.25 MHz, 120 dBV
Measure 10.7 MHz component of output signal voltage at pin 8.
