Reducing Sweep
Time (Using
List Sweep)
The
analyzer
has
a
list sweep
function that
can sweep
frequency according
to a
predened
sweep
segment
list.
Each
sweep segment
is independent.
For
the network/impedance
analyzer
mode
,
each
segment
can have
a dierent
number of
sweep points
, power
level, and
IF
bandwidth
value
.
F
or the
spectrum analyzer
mode,
each segment
can have
a dierent
number
of
points
and
RBW
. Furthermore
,the
output voltage
or current
at
DC
SOURCE
port
can
be
set
for
each
segment
in
all analyzer
modes (option
001 only).

list
1.
Specify
sweep
segments
.
A
segment
looks
like
a
normal
sweep
setting.
The
list
sweep
function can
combine up
to
51
segments
settings
for
network
or
impedance
analyzer
mode
and
15
segments
settings
for
spectrum
analyzer
mode
into 1
sweep.
Y
ou
may
want to
use the
list sweep
function primarily
to
reduce
the
time
required
for
the
sweep
process
.
The
4395A does
not require
that
the
sweep
segments
be
contiguous
.
Therefore
,
you
can
speed
up the
sweep process
using
the
following
strategy:
Dierentiate
the sweep
range
of
interest
from
other
sweep
ranges
in
terms
of
the
number
of
points
(

9-1
).

oints
2. Determine the following parameters before editing the sweep list.
Parameter Description
Sweep P
arameter Frequency of each segment. Each segment cannot be continuous
.
Zero span can be set.
Number of points Number of display points.You can adjust the display area for each
segment by setting this parameter.Total number of points for all
segments is 801 points maximum.
