8. When this is the case, calculate crosstalk C.T.I.2 between 2
inputs by the following formula:
C.T.I.2 = 20LOG

9. As in the same manner, find crosstalk between 2 pints in
response to input into pin 12 and pin 14 only.
C.T.I.3 Crosstalk 3 between 2 inputs
C.T.I.4 Crosstalk 4 between 2 inputs (100 MHz)
Specify input signal to be SG4. In the same manner as in C.T.I.1
and C.T.I.2, find crosstalk C.T.I.3/C.T.I.4 between 2 inputs.
C.T.C.1 Crosstalk 1 between channels
C.T.C.2 Crosstalk 2 between channels (10 MHz)
1. The conditions shall be as provided in the Electrical
Characteristics Table. This measurement shall take active
probe.
2. Assign SW17 to GND and input signal SG3 into pin 2 only.
Specify the output amplitude of T.P.31 to be VOR5 at that time.
3. In the same status, measure the output amplitude of T.P.28 and
T.P.25and specify the values to be VOG5 and VOB5.
4. When this is the case, calculate crosstalk C.T.C1 between
channels by the following formula:

5. In the same manner, find crosstalk between channels in
response to inputs into pin 4 and pin 6 only.
6. Assign SW17 to OPEN and then input signal SG3 into pin 10
only. Specify the output amplitude of T.P.31 to be VOR6 at that
time.
7. In the same status, measure the output amplitude of T.P.28 and
T.P.25. Specify the values to be VOG6 and VOB6.
8. When this is the case, calculate crosstalk C.T.C.2 between
channels by the following formula:
C.T.C.2 = 20LOG

9. As in the same manner, find crosstalk between channels in
response to inputs into pin 12 and pin 14 only.
C.T.C.3 Crosstalk 3 between channels
C.T.C.4 Crosstalk 4 between channels (100 MHz)
Specify input signal to be SG4. In the same manner as in C.T.C.1
and C.T.C.2, find crosstalk C.T.C.3/C.T.C.4 between 2 channels.
