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
35 (35) 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
frequency at which
MHz
the output
amplitude on pin
MHz
35 (35) is 3dB
down from the
1 kHz applied
MHz
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
35 (35) when mute
is turned on and
turned off to find
dB
mute attenuation.
