Measure the output amplitude when 0dB is applied to the chroma Color:1000000

inputand when +6dB is applied to the chroma input. And calculate

the ratio between them.

ACCM1_P=20log(+6dBdata/0dBdata)

Measure the output amplitude when –20dB is applied to the Color:1000000

chroma input and calculate the ratio between them.

ACCM2_P=20log(-20dBdata/0dBdata)

Refer to 5. and measure Bout output amplitude Vb and ROUT output Color:1000000

amplitude Vr. And calculate RB_P=Vr/Vb.

Measure Bout output amplitude Vbp and GOUT output amplitude

Vgbp. And calculate GB_P=Vgbp/Vbp.

Color:1000000

Measure ROUT output amplitude Vrp and GOUT output amplitude

Vgbp. And calculate GR_P=Vgrp/Vrp.

Color:1000000

Refer to 5. and measure the B-Y and R-Y demodulation angle and

calculate.

Color:1000000

Reduce the input signal until the output Level becomes 75mVp-p Color Killer

or less. Measure the input level at that moment.

Ope.:00

Reduce the input signal until the output Level becomes 75mVp-p Color Killer

or less. Measure the input level at that moment.
