C.T.I.1, C.T.I.2 Crosstalk between Two Input

1. The condition is shown as Table. This test is by active prove.

2. Set SW19 to GND, SG3 as the input signal of pin 2. Measure the amplitude output from T.P.35.The amplitude is as

VOR3.

3. Set SW19 to OPEN, measure the amplitude output from T.P.35. The amplitude is as VOR3'.

4 The crosstalk between two inputs C.T.I.1 is

C.T.I.1 = 20log VOR3' [VP-P] [dB]

VOR3 [VP-P]

5. By the same way, measure the crosstalk between two inputs when SG3 as the input signal of pin 5, pin 7.

6. Next, set SW19 to OPEN, SG3 as the input signal of pin 11, measure the amplitude output from T.P.35. The

amplitude is as VOR4.

7. Set SW19 to GND, measure the amplitude output from T.P.35. The amplitude is as VOR4'.

8 The crosstalk between two inputs C.T.I.2 is

C.T.I.2 = 20log VOR4' [VP-P] [dB]

VOR4 [VP-P]

9. By the same way, measure the crosstalk between channels when SG3 as the input signal of pin 13, 16.

C.T.I.3, C.T.I.4 Crosstalk between Two Input

Set SG4 as the input signal, and then the same method as Table, measure C.T.I.3. C.T.I.4.

C.T.C.1, C.T.C.2 Crosstalk between Channel

1. The condition is as Table. This test is by active prove.

2. Set SW19 to GND, SG3 as the input signal of pin 2. Measure the amplitude output from T.P.35. The amplitude is

as VOR5.

3. Next, measure T.P.30, T.P.27 in the same state, and the amplitude is as VOG5, VOB5.

4. The crosstalk between channels C.T.C.1 is

C.T.C.1 = 20log VOG5 or VOB5 [dB]

VOR5

5. Measure the crosstalk between channels when SG3 is as the input signal of pin 5, pin 7.

6. Next, set SW19 to OPEN, SG3 as the input signal of pin 11, measure the amplitude output from T.P.35. The

amplitude is as VOR6.

7. Next, measure the amplitude output from T.P.30, T.P.27 in the same state. The amplitude is as VOG6, VOB6.

8. The crosstalk between channels C.T.C.2 is

C.T.C.2 = 20log VOG6 or VOB6 [dB]

VOR6

9. By the same way, measure the crosstalk between channels when input signal to pin 13, 16.

C.T.C.3, C.T.C.4 Crosstalk between Channel

Set SG4 as the input signal, and the same method as Table, measure C.T.C.3, C.T.C.4.
