GENERAL

INFORMATION

1.1

Description

and

Purpose

The

R

-

110

receiver

,

shown

in

the

frontispiece

,

is

a

solid

-

state

multiple

-

conversion

receiver

that

provides

a

means

of

detecting

and

measuring

signals

associated

with

electromagnetic

analysis

,

TEMPEST

,

spectrum

analysis

,

and

frequency

surveillance

,

in

the

range of

1

Khz

to

1

Ghz

.

Three

basic

modes

of

operation

are

incorporated

into

the

instrument

:

manual

operation

,

automated

sweeping

,

and

remote

operation

controlled

by

a

host

computer

.

The

receiver

will

also

work

with

various

accessories

such

as

the

R-

1180

Microwave

Downconverter

,

which

extends

the

frequency

range

to

18

GHz

.

1.2

Equipment

Description

The

R

-

110

receiver

consists

of

modularly

-

constructed

electronic

circuits

integrated

with

a

front

panel

assembly

containing

operator

controls

and

indicators

.

RF

,

video

,

and

analog

signals

are

interconnected

by

dedicated

connectors

located

on

the

front

and

back

panels of

the

instrument

.

Function

control

signals

and

interface

data

used

by

separately

mounted

equipment

are

provided

through

multi

-contact

connectors

that

use

distinctive

configurations

to

prevent

improper

positioning

when

mated

.
