INTRODUCTION

AND

DESCRIPTION

1.

The

Model

532A/B

direct-reading

frequency

me

ters

offer

good

accuracy

over

an

entire

waveguide

band.

The

meter

consists

of

a

TE^j^i

mode

resonant

cavity

coupled

to

a

waveguide

section.

When

tuned

to

resonance,

a

fraction

of

the

power

is

absorbed,

and

consequently

there

is

a

dip

of

about

1

dB

in

the

transmitted

power.

The

frequency

at

which

this

dip

occurs

may

be

read

directly

from

the

scale.

2.

The

high-Q

resonant

cavity

is

tuned

by

a

choke

plunger.

Adjustment

of

the

plunger

is

by

means

of

a

precision

lead

screw

which

is

spring-loaded

to

pre

vent

backlash.

There

are

no

sliding

contacts.

The

base

of

the

532A/B

will

accommodate

the

shaft

insert

of

a

waveguide

stand

such

as

the

HP

Model

11540A.

INSTALLATION

3.

UNPACKING

AND

INSPECTION.

4.

The

frequency

meter

was

carefully

inspected,

mechanically

and

electrically,

prior

to

shipment.

In

spect

it

for

mechanical

damage

incurred

i

n

transit,

check

for

supplied

accessories,

and

test

electrical

performance.

If

there

is

damage

or

deficiency,

notify

the

carrier

and

the

nearest

Hewlett-

Packard

office

(HP

offices

are

listed

at

the

rear

of

this

manual).

In

the

event

of

mechanical

damage,

the

packing

materials

and

carton

should

be

held

for

carrier's

inspection.

5.

REPACKAGING

FOR

SHIPMENT.

6.

USING

ORIGINAL

PACKAGING.

The

same

con

tainers

and

materials

used

in

factory

packaging

can

be

obtained

through

the

Hewlett-Packard

sales

and

service

offices

listed

at

the

rear

of

this

manual.

7.

If

the

Model

532A/B

is

being

returned

to

Hewlett-

Packard

for

servicing,

attach

a

tag

indicating

the

type

of

service

required,

return

address,

model

number

and

full

serial

number.

Also,

mark

the

container

FRAGILE

to

assure

careful

handling.

In

any

correspon

dence

refer

to

the

instrument

by

model

number

and

full

serial

number.

8.

USING

OTHER

PACKAGING.

The

following

general

instructions

should

be

used

for

repackaging

with

com

mercially-available

materials:

a.

Wrap

the

instrument

in

heavy

paper

or

plastic.

(If

shipping

to

a

Hewlett-Packard

service

office

or

center,

attach

a

tag

indicating

the

type

of

service

re

quired,

return

address,

model

number,

and

full

serial

number.)

b.

Use

a

strong

shipping

container.

A

double-wall

carton

made

of

350

pound

test

material

is

adequate.

c.

Use

enough

shock-absorbing

material

(3-

to

4-inch

layer)

around

all

sides

of

the

instrument

to

provide

firm

cushion

and

prevent

movement

inside

the

con

tainer.

Protect

the

dial

windows

with

cardboard.

d.

Seal

the

shipping

container

securely.

e.

Mark

the

shipping

container

FRAGILE

to

assure

careful

handling.

ALIGNING

FLANGES.

10.

Be

sure

to

align

the

flanges

closely

with

connecting

equipment

when

making

the

initial

setup.

This

will

help

reduce

reflections

due

to

poor

flange

mating.

11.

PRECAUTION.

12.

Protect

flanges

from

damage.

Scoring

or

burring

of

the

mating

surfaces

may

degrade

performance.

Keep

flange

covers

on

when

frequency

meter

is

not

in

use.

A

setup

is

indicated

in

Figure

2.

A

detector

and

meter

are

required

to

indicate

the

resonant

point.

The

attenuator

(10

dB

or

more)

prevents

a

shift

in

signal

frequency

as

the

fre

quency

meter

is

tuned

through

resonance.

The

detector-

meter

combination

can

be

either

a

bolometer

and

power

meter

such

as

an

HP

Model

431B/C

or

a

detector

and

high-gain

voltmeter

such

as

the

HP

ModeI415D.

Either

a

crystal

or

barretter

(mounted

in

a

waveguide

detector

mount

such

as

the

HP

Model

485B)

can

be

used

with

the

415D.

The

RF

source

must

be

modulated

with

a

Swept-Frequency

Setup

20.

With

any

swept-frequency

setup,

the

frequency

at

which

the

wavemeter

is

set

is

indicated

by

an

absorp

tion

of

power

at

a

particular

frequency.

This

absorp

tion

at

a

particular

frequency

is

indicated

as

a

notch

in

the

baseline.

To

determine

that

a

notch

is

due

to

the

frequency

meter

and

not

due

to

the

device

under

test,

move

the

wavemeter

while

watching

the

notch.

If

the

notch

moves,

it

is

due

to

the

frequency

meter.

The

frequency

at

the

notch

can

be

read

by

observing

the

reading

under

the

black

vertical

line

between

the

two

horizontal

red

lines.

21.

MAINTENANCE

22.

No

maintenance

is

necessary

on

the

Model

532A/B

except

keeping

the

flange

covers

on

when

not

in

use

and

the

usual

protection

against

mechanical

damage.

Keeping

the

frequency

meter

in

a

plastic

bag

while

not

in

use

will

help

prevent

the

entrance

of

dust

and

dirt.

i.

Read

the

To

determine

percent

For

example,

if
