01

In

addition

to

the

standard

features

of

the

FM/AM-1200S/A,

several

optional

features

are

available.

These

include:

OPTION

02

The

.05

PPM

Frequency

Standard

provides

the

most

stable

frequency

stan-

dard

available

for

the

FM/AM-1200S/A.

The

.05

PPM

oven

oscillator

is

powered by

the

internal

battery

when

the

test

set

is

switched

to

battery

operation.

The

FM/AM-1200S/A

will

turn

on

and

operate

immediately

in

the

battery

mode

but

the

oven

oscillator

will

not

be

within

specifications

without

a

required

15-minute

warm-up

period

(with

the

test

set

at

room

temper-

ature).

Since

the

operation

period

using

battery

power

is

limited

to

approximately

30

minutes,

it

is

therefore

recommended

that

the

FM/AM-1200S/A

be

connected

to

an

external

AC

or

DC

power

source

for

the

required

15-minute

warm-up

period.
