ISOLATION (FIGURE 8)
This is the cross talk between Ach and Bch.
1) Pin 5 is in the open condition, or low level.
2) Connect AC volt meters to Pin 2 and Pin 3.
3) Connect a capacitor and a resistance to GND
from Pin 4.
4) Input a sine wave (10 kHz, 1 Vrms) to Pin 2.
5) Measure the level of Pin 2 and name this V3.
6) Measure the level of Pin 3 and name this V4.
7) Calculate:
ISO = 20 Log (V4 / V3)
This value is the isolation to Ach from Bch.
8) Next, connect Pin 5 to the V
, or high level.
9) Change line of Pin 2 and Pin 4.
10) Input the same sine wave to Pin 4.
11) Measure and calculate in the same way.
This value is the isolation to Bch from Ach.

RESIDUAL NOISE (FIGURE 7)
This value is not S/N ratio. This is a noise which occurs from
the device itself.
1) Pin 5 is the open condition, or low level.
2) Connect an AC volt meter to Pin 3.
3) Connect a capacitor from Pin 4 to GND.
4) Measure AC voltage of Pin 3. This value is the noise of
1-Ach. If the influence of noise from outside exists, use
optional filters.
5) Next, connect Pin 5 to the V
, or high level.
6) Connect to GND through a capacitor from Pin 2.
7) Measure in the same way.
This value is the noise level of 1-Bch.
