This chapter

the

system

,

performing the

operator's

and

instructions for

using

the

network

analyzer

performance

test

software

.

The operator's

check

can

be

used

as

a

quick

80%

condence

test.

The

only

equipment

required

for

this

check

is

a

type-N

cable

and

a

good

quality

50

type-N

load

(75

for option

1EC).

The

performance

tests

will

verify

that

the

analyzer

meets

its

published

specication

with

greater

than

a

95%

condence

level.

The

performance

tests

are

completely

automated.

The

performance test

software is

written for

an

HP

9000

Series

200

or

300

computer

(or

equivalent)

using HP

BASIC.

There are

no

manual

tests

provided,

nor

are

any

provided.

Note

If

you

would

like to

order the

Performing

the Operator's

Check

The

operator's

check

should

be performed

when you

receive your

analyzer,

and any

time you

wish

to

be

condent

that

the

analyzer is

working properly

. The

operator's check

does not

verify

that

the

analyzer

is

performing

to specications

. Its

purpose is

to provide

you with

a

high

degree

of

condence

that

the

analyzer is

performing properly

if it

passes.

The operator's

check

consists

of

making

a transmission

measurement with

the cable

that was

supplied

with

your

analyzer

,

a

reection

measurement

with the

same cable

,and

a

measurement

with

a

50

(or

75)

termination.

Use

a

known-good

load, such

as one

from calibration

85032B/E

or

This concludes

the Operator's

Check. However

, further

condence can

be obtained

by

performing the

following:

Measure the

175 MHz

lter supplied

with

the

analyzer

to

verify

that

its

measured

response

is

the same

as is

expected. V

erify

both

the

frequency

accuracy

and

noise

oor

.

Check broadband

response with

lter using

conversion-loss

mode

(same

as

B*/R*).

If the

analyzer's frequency

accuracy

is

critical

for

your

application,

verify

a

CW

frequency

using a

frequency counter

.

V

erify

to

6

.005%

accuracy

(for

example

,

The frequency counter is useful when very accurate frequency measurements are needed. However, if you are

using a synthesized spectrum analyzer, the frequency can be measured by using the analyzer (thus eliminating

another piece of equipment). Note that the frequency measurement using a spectrum analyzer will not be quite as

accurate as a frequency counter, but it is sucient in most cases.

However

,it

is

possible

to

In

this

The

HP-IB

The

rst

selection

is

the

Please

note

that

this

is

the

only

address

that

has

both

the

This

can

be

any

The

ISC

does

not

have

to

be the

same as

all

the

other

equipment

(which

must

be

all

on

the

same

ISC).

Generally

the

full address

for the

DUT is

set to

either

716

or

816.

This

also

sets

the

ISC

to

7

or

. The

factory default

HP-IB device

address

for

the

analyzer

is

16.

The

ISC

for

(7).

The

second selection

is the

for

all

the

associated

This

is

generally

7

or

8 and

may be

the same

as that

for

the

.

The power

meter model

number (HP

and

(13).

The

selections

are

for the

power meter

model number

and address

.

Caution

The program will accept the HP 436A power meter as a valid selection, but

it is

not recommended or supported and may cause the program to halt execution.

The spectrum analyzer (HP 8566B) and address (18).

Next is the spectrum analyzer

selection. Any of the

listed models will suce

, but keep in mind that if you do not use a

frequency counter

, then the

spectrum analyzer must have high degree of frequency accuracy

since it will be used as

the frequency counter

.

The function generator model number (HP 8116A) and address (14).

The next selection is

for the function generator and address. The HP 8116A is the only valid selection at this time.

Since

this

The
