INTRODUCTION

The

Motorola

Transistorized

AC

Voltmeters

offer

many

advantages

not

found

in

a-c

vacuum

tube

voltmeters.

Small

physical

size,

light

weight

and

full

transistorization

permit

com-

plete

portability

for

field

use.

Тһе

absence

of

heat

producing

elements,

such

as

tubes

and

transformers,

lessens

the

need

for

frequent

re-

calibration

and

increases

component

life,

The

.Model

S1051C.is

battery

operated.

The

Model

„

51053С,

in

to

con-

tains

an

which

operates

DESCRIPTION

а.

Functions

These

transistorized

a-c

voltmeters

are

ca-

pable

of

accurately

performing

the

following

func-

tions:

(1)

AC

voltage

measurement

from

0.1

milli-

volt

to

300

volts

in

а

frequency

range

of20

cycles

per

second

to

1

megacycle.

(2)

Power

measurements

from

-72

to

+52

dbm

when

measured

across

600

ohm

impedance

(0

dbm

-

1

milliwatt

into

600

ohms).

(3)

Comparative

power

measurements

from

-72

to

+52

db

(when

measured

at

the

same

imped-

ance

level).

(4)

High

gain

isolation

amplifier

with

high

input

resistance

and

low

impedance

output

for

amp-

lification

of

low

level

audio

or

r-f

signals.

b.

Instrument

Characteristics

This

instrument

is

similar

to

many

other

a-c

voltmeters

in

that

the

meter

movement

responds

to

average

values

of

applied

voltages.

The

meter

Scale

is

calibrated

to

read

the

rms

value

of

a

sinusoidal

waveform.

When

the

input

waveform

departs

from

a

pure

sine

wave,

the

meter

indica-

tion

will

be

in

error

by

the

ratio

of

the

average

value

to

the

rms

value

of

the

incoming

waveform.

(See

figures

1

and

2

in

paragraph

8.)

c.

Construction

Although

primarily

designed

for

laboratory

use,

these

instruments,

being

self-powered,

are

quite

suitable

for

portable

use

without

sacrificing

the

accuracy

or

versatility

ofalaboratory

instru-

ment.

A

detachable

metal

cover

protects

the

front

panel

from

damage

that

might

occur

in

portable

use.

Clips

for

storing

the

meter

cable

or

other

accessories

are

mounted

on

the

inside

of

the

cov-

er;

d.

AC

Power

Supply

The

power

supply

of

the

Model

51053С

con-

tains

a

conventional

half-wave

diode

rectifier

cir-

cuit

with

а

capacitor

input

filter

connected

to

the

output.

А

Zener

diode

is

connected

across

the

output

for

voltage

regulation.

The

input

step-down

transformer

is

installed

in

the

line

cord

circuit

and

isolates

the

instrument

case

from

the

a-c

source,

Тре

of

the

METER

SCALES

The

meter

is

calibrated

in

two

linear

a-c

voltage

scales,

a

decibel

scale

anda

battery

con-

dition

scale,

It

uses

а

movement

with

non-linearity

less

than

19

of

full-scale

deflection.

Damping

is

adjusted

to

eliminate

'overshoot''

for

convenience

in

reading

the

pointer

indication.

The

meter

scales

and

their

applications

are

as

follows:

a.

AC

Voltage

Scales

The

two

linear

scales

(black)

are

used

to

mea-

sure

rms

values

of

a-c

voltages,

The

upper

scale

is

graduated

to

a

full-scale

value

of

1.0

and

the

lower

scale

is

graduated

to

a

full-scale

reading

of

3.2.

these

scales

b.

Decibel

Scale

The

DECIBEL

scale

(red)

is

used

for

dbm

measurement

when

measuring

power

level

into

а

600

ohm

impedance

or

comparative

db

levels

when

measured

at

the

are

located

on

the

-METER-OUTPUT

Function

Switch

(Model

S1051C)

This

switch

permits

a

check

of

the

internal

battery

condition

under

load

in

addition

to

turn-

ing

the

instrument

on

or

off,

The

meter

is

con-

nected

to

the

battery

under

a

simulated

load

when

the

switchis

placedinthe

may

be

made

in

the

in

the

tion.

с.

OFF-B+CHK,-METER-OUTPUT

Function

Switch

(Model

S1053C)

This

is

an

8-position

(continuous

rotation)

switch

which

performs

four

functions:

OFF,

Bt

CHK.,

METER

and

OUTPUT

(see

photograph

on

frontispiece

of

this

manual).

The

markings

on

the

knob

(pointer

marks

labeled

LINE

BATT)

automatically

indicate

whether

the

internal

bat-

tery

or

the

a-c

line

is

in

use

as

a

power

source.

METER

and

OUTPUT

functions

are

the

same

as

those

described

in

the

preceding

paragraph.

d.

Input

Terminations

The

units

are

equipped

with

two

binding

posts

that

are

mounted

on

a

molded

polystyrene

base

se-

lected

for

its

low

loss

characteristics

at

high

fre-

quencies.

These

'six-way''binding

posts

are

used

to

make

electrical

connections

with

single

and

double

pin

banana

type

plugs,

tipped

plugs,

spade

lugs,

alligator

clips

and

bare

wire.

e.

Output

Termination

The

units

are

equipped

with

a

BNC

coaxialre-

ceptacle

which

is

mounted

on

the

front

panel.

This

receptacle

furnishes

amplifier

output

for

external

applications

when

the

function

selector

switch

is

in

the

OUTPUT

position.

WARNING

The

voltmeters

have

the

GND

terminal

connected

to

the

instrument

case.

Ex-

treme

caution

should

be

exercised

when

connecting

this

terminal

to

off

ground

potentials

(referenced

to

ground

of

the

circuit

being

measured)

to

minimize

shock

hazard

to

operating

personnel.

When

high

d-c

potentials

are

present,

connect

а

large

coupling

capacitor

in

series

with

this

terminal

and

a

l-meg-

ohm

resistor

between

this

terminal

and

referenced

ground

of

the

circuit

being

measured.
