+Source and
NNNNNNNNNNNNNNNNNNNNNNNNNN
X Source
You can set the marker sources as channels, functions, histograms,or
memories.For example, you can set the +Source function to a waveform
memory and the X Source function to a channel. The scale used to position
each marker on the display is based on the scale of the waveform source that
the marker is tied to.You can select a marker source that is turned o, which
prevents the markers from displaying on the screen. If you cannot see a
marker on the screen, check to see if the marker source is turned o. Also,
when you are placing markers on a waveform, make sure that the source is
set to that waveform.

Position
The +
marker
is
controlled
by
the
+P
osition
function
and
the
X
marker
is
controlled by
the
X
P
osition
function.
Use
the
knob
,
arrow
keys
,
or
keypad
to
position the
markers
on
the
signal.
The
marker
position
readouts
are
displayed
near
the
bottom of
the
display
.
Each
waveform
marker
has
a
Y
position
and
an X
position.
V
ertical
measurements
are
made
with
the
Y
positions
,
and 1Y
is
the
dierence
between
the
Y
positions
.
Timing
measurements
are
made with
the
X
positions
,
and
1X
is
the
dierence
between
the X
positions.
Also
,
notice
1/1X.
If
you
are
using
the
markers
to
measure
the
period
of
a
signal,
then
1/1X
is
the
frequency
of
that
signal.
