Leader LAG-125 Low Distortion Audio Generator

Description

Th
e
LAG-125
is
particularly
designed
for
measurements
and
tests
of
audio
equipment
and
circuits.
The
three
different
types
of
outp
ut
signals
will
find
many
applications
in
testing
high
fidelity
amplifiers,
filter
networks,
and
loudspeakers.
FEATURES
*
Wide
frequency
range,
10Hz
to
1MHz,
with
flat
output
response.
*
Low
distortion
sine
wave
output.
*
Clean-cut
square
waves
for
transient
response
testing
and
triggering
pulse
generators.
*
Burst
type
signals
for
loudspeaker
testing.
*
Calibrated
attenuator,
and
voltmeter
for
accurate
output
control.
*
Pushbutton
frequency
ranging.
*
