OPERATING

CONSIDERATIONS

Introduction

The

remainder

of this

section

contains

the

operating

information

required

to

obtain

the

most

effective

perfor-

mance

from

the instrument

.

This

includes

and

controls

and

tions,

andageneral

descriptionofthe operating

and

procedures

for

.

Controls

and

Connectors

Allofthe

major

controls

and

connectors

for

operation

of

the

AM

503

are

located

on

the

front

panel

of

the

unit.A

is

included

in

.

Monitor

Oscilloscope

The

bandwidth

requiredofthe

oscilloscope

used

with

the

AM

503

depends

upon

the

frequencyofthe

signal

being

measured.Oscilloscope

vertical

bandwidth

should

be

at

least

twice

the

frequency

of

the

signal

being

measured

.

Deflection

.

Conventional

current flowing

in

the

direc-

tionofthe

arrow

on

the

current-probe

slider

produces

a

positive

deflectionofthe

oscilloscope

display

.

Ground-clip

Leads

Ground-clip

leads

are furnished

with

some

current

probes

to

ground

the cable

shieldatthe

probe

end

.

The

ground

leadisused

to

reduce

high-frequency

elec-

trostatic

voltages

that

could

couple

into

the

probe

and

cause

errorsinmeasuring

positions

of

the

attenuator

switch

becauseofundesirable

chassis

currents

that

may

appear

in

these

more

sensitive

positions

.

When

observing

high-frequency

signals,

use

the

shortest

practical

ground-clip

lead

available

.

With

the

atermination

is

not

required

because

of

the

internal

impedance

should not be 50Oif

the

used

.

It

will

cause

an
