C.T.1 Crosstalk1 (f = 50 MHz)

Input SG3 (50 MHz) to pin 2 only, and then measure the waveform amplitude output at OUT (29, 32, 35). The

measured value is called VOUT (29, 32, 35). Crosstalk C.T.1 is calculated by the equation below:

VOUT (29, 32)

C.T.1 = 20log

(dB)

VOUT (35)

C.T.1' Crosstalk1 (f = 150 MHz)

Measuring condition and procedure are the same as described in C.T.1, expect SG3 to 150 MHz.

C.T.2 Crosstalk2 (f = 50 MHz)

Input SG3 (50 MHz) to pin 6 only, and then measure the waveform amplitude output at OUT (29, 32, 35). The

measured value is called VOUT (29, 32, 35). Crosstalk C.T.2 is calculated by the equation below:

VOUT (29, 35)

C.T.2 = 20log VOUT (32) (dB)

C.T.2' Crosstalk2 (f = 150 MHz)

Measuring condition and procedure are the same as described in C.T.2, expect SG3 to 150 MHz.

C.T.3 Crosstalk3 (f = 50 MHz)

Input SG3 (50 MHz) to pin 11 only, and then measure the waveform amplitude output at OUT (29, 32, 35). The

measured value is called VOUT (29, 32, 35). Crosstalk C.T.3 is calculated by the equation below:

VOUT (32, 35)

C.T.3 = 20log

(dB)

VOUT (29)

C.T.3' Crosstalk3 (f = 150 MHz)

Measuring condition and procedure are the same as described in C.T.3, expect SG3 to 150 MHz.

Tr Pulse Characteristics1 (4 VP-P)

Control the main contrast (00H) in order that the amplitude of output signal is 4.0 VP-P.

Control the brightness (V30) in order that the Black level of output signal is 2.0 V.

Measure the time needed for the input pulse to rise from 10% to 90% (Tr1) and for the output pulse to rise from 10% to

90% (Tr2) with an active probe.

Pulse characteristics Tr is calculated by the equations below:

Tr = √ [ (Tr2)2 − (Tr1)2 ] (ns)

Tf Pulse Characteristics2 (4 VP-P)

Measure the time needed for the input pulse to fall from 90% to 10% (Tf1) and for the output pulse to fall from 90% to

10% (Tf2) with an active probe.

Pulse characteristics Tf is calculated by the equations below:

Tf = √ [ (Tf2)2 − (Tf1)2 ] (ns)
