(1) Set picture mute to off (P-MODE: Normal1 (000)), UNI-COLOR to 1101000, SHR-TRACKING to SRT-GAIN
maximum (00) and CDE to maximum (11). Input T pulse signal (0.7 VP-P) to TPA.
(2) Set PICTURE-SHARPNESS to maximum (111111) and APACON PEAK f0 to 5 M (11), and monitor pin 43.
(3) When APACON white peak limiter is off (000), measure positive spike amplitude VWPLOFF1.
(4) When APACON white peak limiter is at maximum (111), measure positive spike amplitude VWPLMAX1.
(5) Set UNI-COLOR to center (1000000). When APACON white peak limiter is off (000) and at maximum (111),
measure positive spike amplitudes VWPLOFF2 and VWPLMAX2.
(6) Set UNI-COLOR to minimum (0000000). When APACON white peak limiter is off (000) and at maximum
(111), measure positive spike amplitudes VWPLOFF3 and VWPLMAX3.
(7) Calculate using the following formulae.
GWPL1 = 20 × og (VWPLMAX1/VWPLOFF1) [dB]
GWPL2 = 20 × og (VWPLMAX2/VWPLOFF2) [dB]
GWPL3 = 20 × og (VWPLMAX3/VWPLOFF3) [dB]
