Term Explanation
AM
Frequency:
The
frequency
of
modulating
waveform.
Mod
Depth:
The
Amplitude
Range
of
modulating
waveform.
In
the
0%
Modulation,
the
output
amplitude
is
the
half
of
the
set
one.
In
the
100
％
Modulation,
the
output
amplitude
is
the
same
with
the
set
one.
For
an
external
source,
the
depth
of
AM
is
controlled
by
the
voltage
level
of
the
signal
connected
to
the
Ext
Mod
In
connector
in
the
rear
panel.
+5V
corresponds
to
the
currently
set
depth
100%.
FM
(Frequency
Modulation)
The
modulated
waveform
consists
of
two
parts:
the
Carrier
Waveform
and
the
Modulating
Waveform.
The
Carrier
Waveform
can
only
be
Sine.
In
FM,
the
frequency
of
the
Carrier
Waveform
varies
with
the
instantaneous
voltage
of
the
modulating
waveform.
The
user
interface
of
the
FM
is
shown
as
below.
