11 / 29 page —11— CXA1785AR SW5 →a, SW46→ON Input SG2 (100 kHz) to (A) and adjust V42 so that the amplitude of the sine wave at TP22 is 0.5 VP-P. With SG2 at 1.8 MHz, Gp5 and Gp6 are the amount of change in the output amplitude at TP22 when V48 = 2 V and 3 V. Input SG3 (100 kHz/3.58 MHz, 0 dB) to (A) and measure the output level at TP1 for 3.58 MHz to 100 kHz. SW13 →a Input SG3 (100 kHz/4.43 MHz, 0 dB) to (A) and measure the output level at TP1 for 4.43 MHz to 100 kHz. Input SG1 (APL = 10%, 0 dB) to (A). V1 is the output amplitude (black-black) at TP22. Next, input SG1 (APL = 90%, 0 dB). V2 is the output amplitude (black-black) at TP22. K = (V1- |V1 - V2|) × 100/V1 SW5 →b, SW13→a, V6=3.5 V Input SG5 (4.43 MHz, burst/chroma phase = ±135°) to (A) and measure the amplitude of the chroma signal at TP12. SW13 →a, V6=3.5 V Input SG5 (4.43 MHz, burst/chroma phase = ±135°) to (B) and measure the amplitude of the chroma signal at TP12. SW5 →b Input SG5 (0 dB, +6 dB, -25 dB), (burst/ chroma phase = 180°) to (A). Measure the output amplitude at TP12, labeling the output corresponding to 0 dB, +6 dB and -25 dB as V0, V1 and V2, respectively. GA1 = 20log(V1/V0) GA2 = 20log(V2/V0) SW5 →a Input SG5 (0 dB, +6 dB, -25 dB), (burst/ chroma phase = 180°) to (B). Measure the output amplitude at TP12, labeling the output corresponding to 0 dB, +6 dB and -25 dB as V0, V1 and V2, respectively.
