PREVENTIVE

MAINTENANCE

General

Preventive maintenance consists

of

cleaning, visual

inspection, etc. Preventive maintenance

performed

on

a

regular basis

will

improve

the

reliability

of

this

instrument.

The

severity

of

the

environment

to

which

the

176

is

sub-

jected determines

the

frequency

of

the

maintenance.

Cleaning

The

best

method

of

cleaning the

exterior

of

the

176

is

with a cloth

dampened in a

mild

detergent

and

water

solu-

tion.

Abrasive cleaners should

not

be used. A small

paint

brush

may

also

be

useful

for

dislodging

dirt

on

and around

the

front

panel

controls.

The

best

method

of

cleaning

the

interior

of

the

176

is

to

blowout

the

accumulated

dust

with

dry,

low

velocity

air. Remove

any

dirt

which

remains

with a soft

paint

brush

or a cloth

dampened

with a mild

soap and

water

solution. A cotton-tipped

applicator

is

also

useful

for

cleaning

the

narrow

spaces on

circuit

boards.

Avoid

the use

of

chemical cleaning agents which might damage the plastic used in this instrument. Avoid

chemicals which contain benzene, toluene,

zylene, acetone or similar solvents.

The

air

filter

should be visually checked every few weeks

and cleaned

or

replaced

if

dirty.

More

frequent

inspections

are required under severe operating

conditions.

If

the

filter

3-2

is

to

be replaced,

order

new air

filters

from

your

local

Tektronix

Field

Office

or

representative.

The

following

pro-

cedure

is

suggested

for

cleaning

the

filter:

1. Remove one

of

the

plastic side panels

from

the

176

and slide

out

the

blue

front

panel.

The

filter

may

now

be

pulled

out

of

the

retaining

frame

in

front

of

the

fan.

2.

Flush

the

loose

dirt

from

the

filter

with

a stream

of

hot

water.

3.

Wash

the

filter

in soap and

hot

water.

4. Rinse

the

filter

in clear

water

and

allow

it

to

dry.

5. Re-install

the

filter

in

the

retaining frame,

then

re-

place

the

front

panel and

the

side cover.

Visual Inspection

A

brief

visual inspection

of

the

176

should precede

any

performance

check

or

readjustment.

In

making

a visual

inspection,

look

for

broken

connectors, loose

connec-

tors, heat damaged parts and damaged

circuit

boards.

Performance Check

and

Readjustment

To

insure accurate

operation,

the

performance

of

the

176

should be checked

after

each

1000

hours

of

operation

or

each six

months,

and,

if

necessary, readjusted.

In

addi-

tion,

replacement

of

components

may

necessitate readjust-

ment

of

the

instrument.

DESCR IPTION

The

Current

Fixture

performs

three

major

functions:

(1) It provides a high

current,

pulsed,

collector

supply

output.

(2) It provides pulsed

steps

and

offset

(for

the

5 highest

current

positions

of

the

Type

AMPLITUDE switch)

with

amplitudes

ten

times

greater

than

It increases

(for

the

ten

times.

The

176

base pulse amplifier receives pulsed steps

from

the

Type

step

amplifier

of

1/2

volt per

step

through

P361 pin 7 (see Fig.

4-1

and

the

In

addition,

the

wide pulses

from

the

Type

through

P361 pin 8.

The

transforms

these pulsed voltage steps and pulses

into

pulsed

steps

with

amplitudes

that

are

10

times greater

than

the

When

are applied

through K 130

to

the

base

of

the

device

under

test.

The

pulsed collector

circuit

in

the

176

produces

the

pulsed

output.

To

obtain

these

pulses,

the

Type

576

Collector

Supply

charges a charge line

in

the

pulsed

collector

supply

circuit.

The

charge line

is

then

discharged

into

the

collector

of

the

device

under

test

during

a

300

!1S

(or

80

interval.

The

pulsed

collector

supply

circuit

is

divided

into

three

sections;

the

charge lines,

the

charge line trigger amplifiers, and

the

SCR

current

switches.

Each charge

line

is

an

open-ended

delay

line. It

is

charged

by

the

collector

supply

during

the

positive half

cycle. During

the

negative half

of

the

cycle, it

is

discharged

into

the

collector

of

the

device

under

The

charge line trigger amplifiers receive

300

!1S

(or

80

pulses from

the

Type

576

step

generator

through

P361

When a charge line trigger amplifier

is

turned

on,

it

amplifies

these

pulses and applies

them

to

associated SCR

current

switches. When

turned

on

by

a charge line trigger

amplifier,

the

SC R current

sw

itches provide

current

paths

between

a charge line and

the

collector

terminal

of

the

device

under

test.

Since

the

charge line trigger amplifiers are

triggered

by

the

same pulses

that

trigger

the

base pulse

amplifier, pulsed

steps

are applied

to

the

base

of

during

the

that

is

The

CIRCUIT

DESCRIPTION

Base

Pulse

Amplifier

The

base pulse amplifier

produces

current

steps

by

applying voltage across a

current

setting resistor.

The

current

conducted

by

the

resistor

is

then

applied

to

the

device

under

test.

The

current

step

amplitude

is

determined

by

the

size

of

the

current

setting resistor.

Differential amplifier

0208A

and

0208B

control

the

voltage across

the

current

setting resistor,

R265

(see Fig.

4-2).

To

obtain

positive-going

current

steps, negative-going

voltage

steps

are applied

through

R207

to

the

base

of

0208A.

These

steps

produce

negative-going voltage

steps

at

the

collector

of

0208B,

which

are applied

to

the

base

of

0260.

When negative-going voltage

steps

are applied

to

the

base

of

0260.

Positive-going voltage

steps

are developed

at

the

collector

of

0260,

SECTION

PERFORMANCE

CHECK

AND

ADJUST

GENERAL

Introduction

This section contains

two

procedures: a performance

check procedure and

an

adjust procedure.

The

performance

check procedure provides

instructions

for

checking

the

per-

formance

of

the

176

with

respect

to

the electrical

performance requirements given in

the

center

column

of

the

Section 1 Specification. The adjust procedure provides

instructions

for

making

the

single internal

adjustment

in the

176.

The

176

should be checked and,

if

necessary, readjusted

after

each

1000

hours

of

operation,

or

at least once every

six months,

to

insure

that

it

is

operating

properly.

In

addi-

tion,

the

instrument

may require readjustment

if

compo-

nents have been replaced

or

other

electrical repairs have

been made.

NOTE

The Type

576

must

be

calibrated

and

its

performance

checked

before

the 176 can be

accurately

checked

or

adjusted.

Refer

to Section 5

of

the Type

576

instruc-

tion

manual.

Maintenance

Any

maintenance required

on

the

176

should be com-

pleted

before starting

this

procedure.

If

troubles

occur

in

the

m idd

Ie

of

the

proced ure,

they

be corrected

before proceeding. Repair and servicing

information

is

given
