Test Method (Test condition: V_CC = 9 V/2 V, Ta = 25 ± 3°C)
ON 1. Input sine wave to TPA. (The frequency is variable.)
2. Set #3 amplitude to 20 mVp-p.
3. Set unicolor to maximum (1111111), SRT-GAIN to minimum (00000), APACON peak frequency to 13.5 M
(00), and color detail enhancer (CDE) to center (10).
4. Set picture mute to OFF (P-MODE: Normal 1, 000), and monitor #43.
5. Set picture sharpness to center (1000000). Set input frequency to 100 kHz, and measure the amplitude V₁₀₀.
6. Set picture sharpness to maximum (1111111). Set input frequency to F_AP00, measure the amplitude V_MAX00,
and calculate G_MAX00 using the following equations.
7. Set picture sharpness to minimum (0000000). Set input frequency to F_AP00, measure the amplitude V_MIN00,
and calculate G_MIN00 using the following equations.
8. Set APACON peak frequency to 9.5 M (01). Set input frequency to F_AP01, measure V_MAX01/V_MIN01 and
calculate G_MAX01/G_MIN01.
9. Set APACON peak frequency to 6.4 M (10). Set input frequency to F_AP10, measure V_MAX10/V_MIN10 and
calculate G_MAX10/G_MIN10.
10. Set APACON peak frequency to 4.5 M (11). Set input frequency to F_AP11, measure V_MAX11/V_MIN11 and
calculate G_MAX11/G_MIN11.
G_MAX*** = 20 × log (V_MAX*** ÷ V₁₀₀) [dB]
G_MIN*** = 20 × log (V_MIN*** ÷ V₁₀₀) [dB]
Note: When a spectrum analyzer is used, measure gain for low frequency.
