A

 

Comb

 

Generator

 

is

 

an

 

intentional

 

radiator

 

designed

 

to

 

produces

 

signals

 

over

 

wide

 

frequency

 

range.

 

It

 

was

 

designed

 

for

 

use

 

in

 

EMI

 

test

 

laboratory

 

to

 

verify

 

operation

 

of

 

EMI

 

emissions

 

test

 

equipment.

  

These

 

radiated

 

signals

 

may

 

cause

 

unwanted

 

radio

 

frequency

 

interference

 

to

 

other

 

equipment

 

operating

 

in

 

the

 

vicinity.

  

If

 

you

 

detect

 

any

 

interference

 

increase

 

the

 

separation

 

between

 

Comb

 

Generator

 

and

 

the

 

other

 

equipment.

 

 

Maintenance:

 

 

There

 

are

 

no

 

user

 

serviceable

 

parts

 

inside

 

the

 

unit.

Generator

 

will

 

void

 

warranty.

 

The

 

Comb

 

Generator

 

uses

 

re
