INPUTS

DUAL

ALTERNATE

This

push

button

switch

gives

instant

selection

of

five

different

“displays”

or

modes

of

operation.

The

CHANNEL

A

and

CHANNEL

B

modes

provide

single

trace

display

of

the

selected

channel.

DUAL ALTERNATE

This

switch

provides

dual

trace

display

of

the

CHAN-

NEL

A

and

CHANNEL

B

signals.

The

signal

from

one

input

channel,

CHANNEL

A

for

example,

is

dis-

played

on

the

first

sweep

cycle.

On

the

next

sweep

cycle

the

other

channel

is

displayed.

This

is

the

re-

commended

mode

to

use

for

most

dual

trace

op-

erations.

DUAL

CHOPPED

This dual

trace

mode

is

most

useful

at

slow

sweep

speeds

and

when

it

is

desired

to

have

dual

trace

dis-

play

when

using

the

60

cycle

or

EXT.

sweep

pro-

visions.

The

DUAL

CHOPPED

mode

uses

a

100KHz

square

wave

to

switch

the

input

between

CHANNEL

A

and

CHANNEL

B.

This

will

provide

a

continuous

steady

display

of

both

channels

at

slow

sweep

speeds.

The

DUAL

CHOPPED

mode

is

intended

to

be

used

only

with

the

MANUAL

TRIGGERED

and

FREE

RUNNING

sweep

modes.

The

AUTO

TRIGGERED

function,

because

of

its

extreme

sensitivity,

will

tend

to

trigger

on

the

100KHz

chopping

signal.

VECTOR

A&B

INPUTS

This

display

mode

converts

the

PS163

to

a

full

sensi-

tivity

Vector

scope

or

X-Y

scope.

The

to

CHANNEL

A

will

be

displayed

vertically;

the

input

to

CHANNEL

B

will

be

displayed

horizontally.

CHANNEL

A

and

B

INPUT

CONTROLS

The

CHANNEL

A

and

CHANNEL

B

amplifiers

are

electrically

identical

and

a

description

of

one

will

apply

to

the

other.

sensitivity

of

the

lifiers,

and

The

is

a

that

adjusts

the

of

the

amplifier

between
