INTRODUCTION

The

function

generator

PM

5167

has a

wide

frequency

range

(1

mHz

...

10

MHz)

and

an

extremely

high

output

voltage

(40

V

pp

open

circuitl.

Furthermore

it has a

wide

variety

of

waveforms;

sine

-,

triangular-,

square

wave,

sawtooth

-,

and

pulse

signals.

Excellent

specifications,

features

like e.g.

sweep

input,

single

shot

mode

with

adjustable

start

phase,

hold,

DC-

offset

and

a

compact

construction

make

the

PM

5167

a

versatile

tool

for

electronic

laboratories,

production

and

engineering

design

groups.

2.1.1.

Safety

regulations

( in

accordance

with

IEC

348

or

VDE

0411)

Before

using

the

instrument

af

ter

stocking

and

transport,

pay

attention

that

the

instrument

has

not

been

mechanically

damaged.

If

there

is

a

doubt

about

the

efficieny

of

the

protection,

check

this.

If

the

protection

is

no

longer

guaranteed,

disconnect

the

instrument

from

the

mains

and

make

it

inoperative.

The

instrument

must

be

disconnected

from

the

mains

before

opening.

Maintenance

and

service

works,

which

must

be

done

with

the

instrument

switched

on,

should

only

be

performed

by

qual ified

personnel.

The

mains

connector

may

be

plugged

only

into

a

mains

socket

with

earth

contacts.

This

safety

measure

may

not

be

made

inoperative,

e.g.

with

an

unproper

extension

Seleeting

the

The

can

be

seleeted

by

means

of

the

WAVEFORI'y1

switch.

The

scale

of

this

is

divided

in

two

ranges.

One

range

comprises

the

time-symmetrical

signals

(11

while

the

other

comprises

the

The

is

available

at

Attention:

For

The

by

the

Indicator

occur

due

to

simultaneous

The generator

is

provided

with

a

ce

which

can produce single periods

of

a signal

frequency

and signal

form.

The single shot capabil

ity

is

operative

for

all signal forms and in the

frequency

ranges 1 m ...1k.

The starting

point

can be set

continuously

between the peak values

of

the signal (in accordance

with

Fig.

by

means

of

potentiometer

EINLEITUNG

Der

Funktionsgenerator

PM

5167

besitzt einen breiten Frequenzbereich

(1

mHz ... 10 MHz) und eine besonders

hohe Ausgangsspannung (40 V Spitze -Spitze

im

Leeriauf). Ausserdem liefert das Gerät viele verschiedene Signal-

formen; Sinus-, Dreieck-, Rechteck-, Sägezahn- und Pulssignale.

Ausgezeichnete Spezifikationen, Eigenschaften wie z.B. Sweepeingang, einmalige Auslösung

mit

einstellbarer

Startphase, Haltefunktion, DC-Offset

und

kompakte

Konstruktion machen den

PM

5167

zu einem vielseitigen

Gerät geeignet zur Anwendung

im

Elektroniklabor,

in

der Fertigung und bei technischen Entwicklungsgruppen.

Andere Eigenschaften sind:

-"Overrange"-Anzeige

-Frequenz-Offset Steuerung

-Steuereingang (an der Ruckseite)

-

dB

Abschwächung

Folgende Ausgänge sind vorhanden:

-Ein Ausgangsanschluss an dem eine der Signalformen mit variabler Amplitude, Gleichspannungspegel und

Frequenz-Offset gewählt werden kann.

-Ein Ausgangsanschluss, dem sich ein Rechtecksignal mit fester Amplitude, symmetrisch gegen Null,

mit

einstellbarer Frequenz und wählbarem Tastverhältnis,

entnehmen

lässt.
