The Model

2500

is

specially

designed

for

cellular

testing

and

includes

a

"Go-No-Go"

automatic

mode

for

quick

cellular

telephone

testing.

A

parallel

printer

port

is

provided

so

a

hard

copy

of

the

test

results

can

be

generated

when

a

user

provided

is

connected.

A

manual

mode

enables

the

user

to

program

individual

parameters

for

trouble

shooting

purposes.

A

non-volatile

memory

allows

the

user

to

store

frequently

In

the

Service

Monitor

Mode,

the

Model

2500

generates

and

receives

from

400

kHz

to

999.9999

MHz

in

100

Hz

steps.

The

RF

output

leyel

is

continuously

variable

from

0.1

uVolts

to

10

mVolts

in

five

ranges.

The

Model

2500

contains

a 1 kHz

modulation

source,

a

10

Hz

to

10

kHz

audio

synthesizer

and

an

external

modulation

input.

The

audio

synthesizer

output

has

a

second

independently

variable

output

on

the

front-panel.

Deviation

markers

at

±5

kHz

or

±600

may

be

superimposed

on

the

demodulated

output

for

viewing

on

an

external

oscilloscope

in

both

the

Receive

and

Generate

modes.

The

Model

2500

measures

and

displays

SINAD

dB

or

%

distortion,

volts,

FM

deviation,

signal

strength,

carrier

frequency,

demodulated

audio

frequency,

frequency

and

sub-tone.

Power

may

be

applied

to

the

RF

in/out

connector

for

measuring

R.F.

power

up

to

110

watts

(when

terminated

into

a

true

50

ohm

load).

Twenty

memory

registers

are

available

for

storing

and

recalling

all

front-panel

keyboard

settings.

An

optional

RS-232

interface

and

two

available

software

packages

allow

for

its

use

in

automated

test

systems.
