istics and crosstalk characteristics
(1) Frequency characteristics 1
Use an oscilloscope to input a sine wave (V
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.
(2) Frequency characteristic 2
Use an oscilloscope to input a sine wave (V
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.
(3) Input pin crosstalk 1
Use an oscilloscope to input a sine wave (V
f = 10MHz) to IN1. Connect IN2 to the ground through
a capacitor. Set the switch to 2, input to IN2, then mea-
sure.
(4) Input pin crosstalk 2
Use an oscillator to input a sine wave (V
230MHz) to IN1. Connect IN2 to the ground through a

Procedure for measurement of frequency character-
Gf1 = Gv (f = 1MHz) – Gv (150MHz) [dB]
Gf1 = Gv (f = 1MHz) – Gv (250MHz) [dB]

(5) Block crosstalk 1
Use an oscillator to input a sine wave (V
10MHz) to G1 and R1. Connect B1 to the ground
through a capacitor. Set the switch to 1 and measure
the B output.
