(1) Apply a rainbow color bar signal to pin 39.
(2) Observe the RGB output signal at pin 19, 20 and 21.
Change input fsc frequency by 10Hz step up to ±3kHz. Measure the pull-in
range.

(1) Apply the rainbow color bar signal (fsc = 3.579545MHz, 0.3Vp-p) to pin 39.
(2) Measure the amplitude and phase at pin 19, 20 and 21.
Calculate R / B, G / B, R-B, G-B.

(1) Apply a rainbow color bar signal to pin 39.
(2) Adjust the data of sub-address (01) so that the RGB output amplitude at pin 19,
20 and 21 will be maximum.
(3) Apply the signal that has only sync. and burst signal to pin 39.
(4) Measure the fsc components of RGB output signal at pin 19, 20 and 21.

(1) Apply a rainbow color bar signal to pin 39.
(2) Measure the amplitude of RGB output signal at pin 19, 20 and 21 when the data
of sub-address (00) is set (7F). (VCLRmax)
(3) Measure the amplitude of RGB output signal at pin 19, 20 and 21 when the data
of sub-address (00) is set (40). (VCLRcen)
GCLRcen = 20og (VCLRmax / CCLRcen)
(4) Measure the amplitude of RGB output signal at pin 19, 20 and 21 when the data
of sub-address (00) is set (00). (VCLRmin)
GCLRmin = 20og (VCLRmax / VCLRmin)
