Conditions

min

T39A T23A In PB mode, with S24: 3 and S23: off, input a

T4A

4 MHz 300 mVp-p continuous wave from

T39A, input a 50% white signal from T4A,

and measure the wave peak at T23A

T21 In PB mode, measure the T21 output level

with an FET probe

480 640 800 mVp-p

Note) A trap (4.84 MHz for NTSC systems and 5.69 MHz for PAL systems) is required in the chroma playback system (between

pins 25 and 27 or between pins 31 and 29) in order to suppress unnecessary components in converter output.
