Use
Cursors
to
Measure
Phase
Difference
between
two
Signals
3.5
The
Application
of
X
‐
Y
Function
Check
the
phase
difference
between
signals
of
the
two
channels
Example:
Measure
phase
difference
caused
when
a
signal
passes
a
circuit.
In
details,
connect
the
oscilloscope
to
the
circuit
and
monitor
the
input
and
output
signals
of
the
circuit.
In
case
we
want
to
check
the
input
and
output
of
the
circuit
on
X
–
Y
coordinate
graphs.
Please
follow
the
following
steps
to
operate:
1
．
Set
the
probe
attenuation
coefficient
to
be
10
×
,
and
set
the
switch
on
the
probe
to
be
10
×
;
2
．
Connect
the
probe
of
CH1
to
the
input
of
the
network,
and
then
connect
the
probe
of
CH2
to
the
output
of
the
network;
3
．
If
channels
have
not
been
displayed,
then
press
down
CH1
and
CH2
menu
keys
to
open
the
two
channels;
4
．
Press
AUTO
key;
5
．
Adjust
the
“vertical
scale
knob”
to
make
the
amplitudes
of
the
two
signals
appear
approximately
equal;
6
．
Press
DISPLAY
menu
key
to
load
the
display
of
control
menu;
7
．
Press
F1
to
select
X
‐
Y.
The
oscilloscope
will
display
the
input
and
output
characteristics
of
this
circuit
in
Lissajous
pattern;
8
．
Adjust
vertical
unit
and
vertical
position
knobs
to
achieve
best
waveform
displaying
effect;
9
．
Observe
and
calculate
the
phase
difference
using
ellipse
oscilloscopic
graphic
method.
