Unit
Test Method
(1) Apply a 1 kHz sine
V
p-p
wave to each input
pin.
V
p-p
(2) In each select
mode, measure an
V
p-p
input amplitude at
which the output
V
p-p
waveform on pin
37 (37) begins to
V
p-p
be distorted.
dB
(1) Apply a 1 kHz,
1.0 V
sine wave
p-p
dB
to each input pin.
dB
(2) In each select
mode, find the gain
dB
between input and
dB
output.
(1) Apply a 1.0 V
p-p
MHz
sine wave to each
input pin.
MHz
(2) In each select
mode, measure a
MHz
frequency at which
the output
MHz
amplitude on pin
37 is 3dB down
from the 1 kHz
MHz
applied level.
(1) Apply a 1 kHz,
dB
1.0 V
sine wave
p-p
to each input pin.
dB
(2) In each select
mode, compare
dB
signal output from
the selected pin
dB
with leakage
components from
nonselected pins
dB
to find a crosstalk.
(1) Apply a 1 kHz,
dB
1.0 V
sine wave
p-p
to each input pin.
dB
(2) In each select
mode, compare
dB
the output
amplitudes on pin
dB
37 (37) when mute
is turned on and
turned off to find
dB
mute attenuation.
