HP 8753D - Using Analyzer Display Markers

Using Analyzer
Display Markers
The
analyzer
markers
provide
numerical readout
of trace
data. Y
ou can
control the
marker
search,
the
statistical
functions
,
and
the capability
for quickly
changing stimulus
parameters
with
markers
,
from
the
4
MARKER
F
CTN
5
key
.
Markers
have
a
stimulus
value
(the
x-axis
value
in a
Cartesian format)
and a
response value
(the
y-axis
value
in
a Cartesian
format). In
a polar
or Smith
chart
format,
the
second
part
of
a
complex
data
pair
is
also
provided as
an auxiliary
response value
.
When
you
switch
on
a
marker
,
and
no
other
function
is active
,the
analyzer shows
the
marker
stimulus
value
in
the
active
entry
area.
Y
ou
can
control the
marker with
the front
panel
knob
,
the
step
keys
,
or
the
front
panel
numeric
keypad.
If
you
activate both
data and
memory traces
,the
marker
values
apply
to
the
data
trace
.
If
you
activate only
the memory
trace,
the marker
values
apply
to
the
memory
trace
.
If
you
activate a
memory math
function (data/memory
or data-memory),
the
marker
values
apply
to
the trace
resulting from
the memory
math function.
The
examples
in
this
section
are
shown with
lter
measurement
results
.
The
measurement

are

Use
Continuous
and
Discrete
Markers
The
analyzer
can
either
place
markers
on
discrete
measured
points
,
or
move
the markers
continuously
along
a
trace
by
interpolating
the
data
value
between
measured
points
.

MARKERS:
DISCRETE if
you want
the analyzer
to place
markers
only
on
measured
trace
points
determined
by
the
stimulus
settings
.
This
may
be
the
best
mode
to
use
with
automated
testing,
using
a
computer
or
test
sequencing because
the analyzer
does not
interpolate
between
measured
points
.

will also aect marker search and positioning
functions when the value entered in a search or positioning function does not
exist as a measurement point.
