It
becomes
inconvenient
to
observe
waveform
when
the
amplitude
of
DC
component
in
a
signal
under
test
is
very
large
relative
to
the
amplitude
of
AC
component
in
that
signal,
as
shown
in
Fig.
2012.

Signal
Containing
DC
Component
Then
we
can
use
bias
voltage
function
to
offset
the
DC
component
in
a
signal,
so
that
the
signal
can
be
displayed
better
on
the
screen.
Once
we
enter
into
the
functional
menu
of
bias
voltage,
we
can
set
bias
voltage
by
turning
MULTIPURPOSE
knob.
As
shown
in

we
can
calculate
the
DC
component
of
a
signal
with
the
use
of
bias
voltage.
