Coupling
Settings
Take
the
application
of
signal
in
CH1
as
an
example,
for
which
the
signal
under
test
is
a
sinusoidal
signal
containing
DC
component.
Press
F1
and
then
use
“MULTIPURPOSE”
knob
to
select
AC
1M
Ω
,
whose
channel
coupling
is
set
as
AC
coupling
mode.
Thus
the
DC
component
contained
in
the
signal
under
test
is
blocked.
