Oscilloscope

Features

The

is

a

solid

instru



ment

designed

for

general-purpose

measuring

appli ations.

This

instrument

has

three

plug-in

om



partments

that

a ept

plug-in

units

to

form

a

measurement

system.

The

two-plug-in

ompartments

on

the

left

are

onne ted

to

the

verti al

defle tion

system.

The

right

plug-in

ompartment

is

onne ted

to

the

defle tion

system.

Ele troni

swit hing

between

the

The

flexibility

of

this

plug-in

feature

and

the

variety

of

plug-in

units

available

allow

this

system

to

be

used

for

many

measurement

appli ations.

This

instrument

features

a

8X10

division

display;

ea h

division

equals

0.5

is

not

affe ted

by

variations

in

line

voltage

and

frequen y,

or

by

hanges

in

the

load

due

to

the

varying

power

re



quirements

of

the

plug-in

units.

Safety

Information

This

of

the

instrument.

Warning

information

and

Caution

information

is

intended

to

To

prevent

dama e

always

check

the

WARNIWG~|

This

instrument

is

intended

to

be

operated

from

a

sin le-phase

earth-referenced

power

source

havin

one

current-carryin

conductor

(the

Neutral

Con



ductor)

near

earth

potential.

Operation

from

power

sources

where

both

current-carryin

conductors

are

live

with

respect

to

earth

(such

as

phase-to-

phase

on

a

three-wire

system)

is

not

recommended,

since

only

the

Line

Conductor

has

over-current

(fuse)

protection

within

the

instrument.

This

instrument

has

a

three-wire

power

cord

with

a

polarized

two-pole,

three-terminal

plu

for

connec



tion

to

the

power

source

and

safety-earth.

The

safety-earth

terminal

of

the

plu

is

directly

con



nected

to

the

instrument

frame.

For

electric-shock

protection,

insert

this

plu

only

in

a

matin

outlet

with

a

safety-earth

contact.

Do

not

defeat

the

roundin

connection.

Any

in



terruption

of

the

roundin

connection

can

create

an

electric-shock

hazard.

Before

makin

external

connections

to

this

instrument,

always

round

the

instrument

first

by

connectin

the

power-cord

to

a

proper

matin

power

outlet.

WARNING

I

To

avoid

electric-shock

hazard,

operatin

personnel

must

not

remove

the

protective

instrument

covers.

Component

replacement

and

internal

adjustments

must

be

made

by

PLUG-IN

UNITS

The

os illos ope

is

designed

to

a ept

up

to

three

Tektronix

5000-series

plug-in

units

(use

only

"N"

suffix

plug-in

units

unless

otherwise

spe ified).

This

plug-in

feature

allows

a

variety

of

display

ombinations

and

also

allows

sele tion

of

bandwidth,

sensitivity,

display

mode,

et .,

to

meet

the

measurement

requirements.

In

addition,

it

allows

the

os illos ope

system

to

be

expanded

to

meet

future

measurement

requirements.

The

overall

apabilities

of

the

resultant

system

are

in

large

part

determined

by

the

hara teristi s

oftheplug-inssele ted.

Installation

To

install

a

plug-in

unit

into

one

or

the

plug-in

ompartments,

align

the

slots

in

the

top

and

bottom

of

the

plug-in

with

the

asso iated

guides

in

the

plug-in

ompart



ment.

Push

the

plug-in

unit

firmly

into

the

plug-in

ompartment

until

it

lo ks

into

pla e.

To

remove

a

plug-in,

pull

the

release

lat h

on

the

plug-in

unit

to

disengage

it

and

puli

the

unit

out

of

the

plug-in

ompartment.

Plug-in

units

should

not

be

removed

or

installed

without

turning

off

the

instrument

power.

It

is

not

ne essary

that

all

of

the

plug-in

ompartments

be

filled

to

operate

the

instrument,

the

only

plug-ins

needed

are

those

required

for

the

measurement

to

be

made.

When

the

os illos ope

is

adjusted

in

a ordan e

with

the

adjustment

pro edure

given

in

this

manual,

the

verti al

and

horizontal

gain

are

standardized.

This

allows

adjusted

plug-in

units

to

be

hanged

from

one

plug-in

ompart



ment

to

another

without

readjustment.

However,

the

basi

adjustment

of

the

individual

plug-in

units

should

be

he ked

when

they

are

installed

in

this

system

to

verify

their

measurement

a ura y.

See

the

plug-in

unit

manual

for

verifi ation

pro edure.

Selection

The

plug-in

versatility

of

the

os illos ope

allows

a

variety

of

display

modes

with

many

different

plug-ins.

The

following

information

is

provided

here

to

aid

in

plug-in

sele tion.

NOTE

Use

only

"N"

suffix

plu -in

units

with

the

os



cilloscope

unless

otherwise

specified.

To

produ e

a

single-tra e

display,

install

a

single



hannel

verti al

unit

(or

dual- hannel

unit

set

for

single



hannel

operation)

in

either

of

the

verti al

(left

or

enter)

ompartments

and

a

time-base

unit

in

the

horizontal

(right)

ompartment.

For

dual-tra e

displays,

eitherinstall

a

dual- hannel

verti al

unit

in

one

of

the

of

a

single- hannel

and

a

verti al

unit

allows

a

three-tra e

likewise,

a

allows

a

four-tra e

To

obtain

a

displayed

horizontally,

insert

the

time-base

unit

into

one

of

the

verti al

and

the

in

the

horizontal

ompartment.

If

a

is

used,

there

is

no

however,

if

used

in

FIRST

TIME

OPERATION

The

following

pro edure

provides

an

operational

he kout

as

a

means

of

verifying

instrument

operation

and

basi

alibration

without

removing

the

abinet

or

making

internal

adjustments.

Sin e

it

demonstrates

the

use

of

front-panel

ontrols

and

onne tors,

it

an

also

be

used

to

provide

basi

training

on

the

operation

of

this

instrument.

If

re alibration

of

the

os illos ope

or

plug-ins

appears

to

be

ne essary,

refer

the

instrument

system

to

qualified

personnel.

If

more

familiarization

with

is

needed,
