operate

as

described

(in

for

the

X-Y

Operation

In

some

applications,

it is

desirable

to

display

one

signal

versus

another

(X-Y),

rather

than

against

the

internal

sweep

.

When

the

DISPLAY

MODE

push

button

is

pressed

and

re-

leased

to

the

OUT

:

X-Y

position,

all

other

front-panel

con-

trols,

the

sweep,

and

readout

functions

of

the

to

the

provided

An

external

X

signal

can

now

be

connected

to

any

vertical

amplifier

unit

and

coupled through

the

internal

triggering

system

of

the

vertical

amplifier

unit,

the main-

frame,

and

the

Option

2

Time

Base

to

provide

the

horizon-

tal

deflection

on

the

mainframe

display

.

The

external

Y

signal

is

connected

to

the

remaining

amplifier

channel

to

provide

the

vertical

deflection

on

the

mainframe

display

.

The

advantages

of

using

the

internal

triggering

system

to

provide

the

X

signal

are

:

1

.

X-Y

operation

is

possible

with

one

dual-trace

amplifier

in

a

mainframe

vertical

compartment

.

2

.

X-Y

operation

is

possible

without

having

to

remove

a

time-base

unit

from

the

horizontal

compartment

of

the

mainframe

to

substitute

an

amplifier

unit

.
