total

deflection

factor

in

the ADD

mode is

equal to

the

deflection

factor

indicated by

either

VOLTS/DlV switch

(when

both

VOLTS/DIV

switches

are set

to

the

same

position

factor). A common

use for

the ADD

mode is

to

provide

a

dc offset

for

a signal

riding on a dc

level.

The

following

general

precautions

should

be observed

when

using

the ADD

mode:

1.

Do

not exceed the

input

voltage rating of the

oscilloscope.

2. Do

not

apply

signals

that

exceed the

equivalent

of

about

eight times the

VOLTS/DlV switch

settings,

since

large

voltages may distort

the

display.

For

example,

with a VOLTS/DlV

switch

setting

of 0.5,

the

voltage applied

to that

channel

should

not exceed

about

four

volts.

EXAMPLE:

Using the

graticule

center line

as

zero

volts,

the Channel

1

signal

is

on a three-division,

positive

dc

level

(see

Figure 16A).
