Procedure for measurement of frequency character-
istics and crosstalk characteristics
(1)Frequency characteristics 1
Use an oscilloscope to input a sine wave (V
IN
= 1.0V
P-P
,
f = 1MHz / 150MHz) to the color signal input pins. Set
the switch to 1 to select B1, G1 and R1, or to 2 to
select B2, G2 and R2.
Gf1 = Gv (f = 1MHz) – Gv (150MHz) [dB]
(2)Frequency characteristic 2
Use an oscilloscope to input a sine wave (V
IN
= 1.0V
P-P
,
f = 1MHz / 230MHz) to the color signal input pins. Set
the switch to 1 to select B1, G1 and R1, or to 2 to
select B2, G2 and R2.
Gf1 = Gv (f = 1MHz) – Gv (250MHz) [dB]
(3)Input pin crosstalk 1
Use an oscilloscope to input a sine wave (V
IN
= 1.0V
P-P
,
f = 10MHz) to IN1. Connect IN2 to the ground through
a capacitor. Set the switch to 2, input to IN2, then mea-
sure.
CTI1 = 20log (V
OUT
/ V
IN
) [dB]
(4)Input pin crosstalk 2
Use an oscillator to input a sine wave (V
IN
= 1.0V
P-P
, f =
230MHz) to IN1. Connect IN2 to the ground through a
capacitor. Set the switch to 2, input to IN2, then mea-
sure.
CTI2 = 20log (V
OUT
/ V
IN
) [dB]
(5)Block crosstalk 1
Use an oscillator to input a sine wave (V
IN
= 1.0V
P-P
, f =
10MHz) to G1 and R1. Connect B1 to the ground
through a capacitor. Set the switch to 1 and measure
the B output.
CTB1B = 20log (V
OUT
B / V
IN
G1) [dB]
Similarly,
CTB1G = 20log (V
OUT
G / V
IN
R1) [dB]
CTB1R = 20log (V
OUT
R / V
IN
B1) [dB]
(6)Block crosstalk 2
Use an oscillator to input a sine wave (V
IN
= 1.0V
P-P
, f =
230MHz) to G1 and R1. Connect B1 to the ground
through a capacitor. Set the switch to 1 and measure
the B output.
CTB2B = 20log (V
OUT
B / V
IN
G1) [dB]
Similarly,
CTB2G = 20log (V
OUT
G / V
IN
R1) [dB]
CTB2R = 20log (V
OUT
R / V
IN
B1) [dB]
