Wet
Signal-to-Noise
This
test checks
Reflex
signal-to-noise
through
the wet
signal
path.
1
. Set
the scale on
the distortion analyzer
to measure
-SOdBV
signal.
2.
Disconnect
the
oscillator from
Reflex,
or
turn the
oscillator
off.
3.
Verify
that
the
noise floor
is <71 dBV.
4.
Connect
the
oscillator
output
to
the Reflex
Left Input.
5.
Connect the
analyzer
input
to
the
Reflex
Left
Output.
6.
Repeat
the
test,
verifying
the levels
at
the
Reflex
Left
Output.
Wet
THD+N
This
test checks Reflex
THD+N
through
the
wet
signal
path.
1
. Apply
a
IkHZ
signal
at
-26dBV
to
the
Reflex
Left Input.
2.
Adjust the scale
on the
distortion analyzer
to measure
.05% THD+N.
3.
Verify
a distortion
level
<0.05%
& >0.005% THD+N
at the
Reflex
Left
Output.
4.
Connect
the
oscillator
output to
the Reflex
Right
Input.
5.
Connect
the
analyzer
input
to
the
Reflex Right
Output.
6. Verify
a
distortion
level
<0.05%
&
>0.005% THD+N
at
the
Reflex
Right
Output.
Wet
Frequency
Response
This
test checks
the
frequency
response
of Reflex
through
its
wet signal
path
at
the
following
frequencies;
15kHz
100Hz
8kHz
20Hz
3kHz
1
. Apply
a
-30dBV
signal
at
1
kHZ
with
the
analyzer BANDWIDTH
filters
off
to
the
Reflex
Right
Input.
2.
Set
the scale
on
the distortion
meter
to measure +4dBV.
3.
Use
the
output level
at the Reflex Right
Output
for
the
OdB
reference
to
check
frequency
response.
4.
Verify
that
the signal
level
output
is within
+1.06dB/-3.56dB
of
the
reference
at
the above
frequencies.
5.
Connect
the
oscillator
output to
the Reflex
Left Input.
6.
Connect
the
analyzer
input
to
the Reflex
Left
Output.
7.
Repeat
the
previous
tests
verifying
levels
for the Reflex
Left
Output.
