TEST CIRCUITS AND METHODS (CONT.)
MAXIMUM INPUT LEVEL (FIGURE 6)
This measurement measures at output side.
1) Pin 5 is in the open condition, or high level.
2) Connect a distortion analyzer and an AC volt meter to
Pin 3.
3) Input a sine wave (1 kHz) to Pin 4 and elevate the
voltage gradually until the distortion gets to
0.1%.
4) When the distortion amounts to 0.1%, stop elevating and
measure the AC level of Pin 3.
This value is the maximum input level of 1-Ach.
5) Next, connect Pin 5 to the GND, or low level.
6) Input the same sine wave to Pin 2.
7) Measure in the same way.
This value is the maximum input level of 1-Bch.

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 high 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 GND, or low 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.
