List

Sweep

The

analyzer

has

a

list

sweep

function

that

can

sweep

frequency

according

to

a

prede ned

sweep

segment

list.

Each

sweep

segment

is

independent.

F

or

the

network

analyzer

mode

,

each

segment

can

have

a

di erent

number

of

sweep

points

,

power

level,

and

IF

bandwidth

value

.

F

or

the

spectrum

analyzer

mode

,

each

segment

can

have

a

di erent

number

of

points

and

RBW

.

A

segment

looks

like

a

normal

sweep

setting.

The

list

sweep

function

can

combine

up

to

31

segments

settings

into

1

sweep

.

The

analyzer

can

have

two

di erent

sweep

lists

.

One

list

for

the

network

analyzer

and

the

other

list

for

the

spectrum

analyzer

.

When

both

channels

are

set

to

the

same

analyzer

mode

,

both

channels

use

the

same

list.

This

example

describes

the

following

two

applications:

Sweep

time

reduction

for

lter

testing

in

the

network

analyzer

mode

(including

the

setup

procedure).

Dynamic

range

enhancement

in

the

network

analyzer

mode

.

Sweep

Time

Reduction

The

following

example

creates

a

list

sweep

to

measure

a

lter

that

has

a

836

MHz

center

frequency

and

a

50

MHz

bandwidth.

This

example

uses

the

list

sweep

to

reduce

the

sweep

time

by

setting

coarse

sweep

points

for

the

rejection

band

and

the

ne

sweep

points

for

the

passband.
