Test Method (Test condition: VCC = 9 V/2 V, Ta = 25 ± 3°C)
ON 1. Input sine wave to TPA. (The frequency is variable.)
2. Set #68 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 #12.
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 FAP00, measure the amplitude VMAX00,
and calculate GMAX00 using the following equations.
7. Set picture sharpness to minimum (0000000). Set input frequency to FAP00, measure the amplitude VMIN00,
and calculate GMIN00 using the following equations.
8. Set APACON peak frequency to 9.5 M (01). Set input frequency to FAP01, measure VMAX01/VMIN01 and
calculate GMAX01/GMIN01.
9. Set APACON peak frequency to 6.4 M (10). Set input frequency to FAP10, measure VMAX10/VMIN10 and
calculate GMAX10/GMIN10.
10. Set APACON peak frequency to 4.5 M (11). Set input frequency to FAP11, measure VMAX11/VMIN11 and
calculate GMAX11/GMIN11.
GMAX*** = 20 × log (VMAX*** ÷ V100) [dB]
GMIN*** = 20 × log (VMIN*** ÷ V100) [dB]
Note: When a spectrum analyzer is used, measure gain for low frequency.
