Description

 

 

Overview

 

 

The

 

model

 

AH

826

 

Horn

 

antenna

 

was

 

specifically

 

designed

 

for

 

EMI

 

measurement

 

from

 

18

 

to

 

26.5

 

GHz.

 

The

 

antenna

 

is

 

capable

 

of

 

receiving

 

and

 

transmitting

 

signals

 

for

 

EMC

 

testing.

 

The

 

Horn

 

antenna

 

is

 

a

 

transducer

 

which

 

converts

 

electric

 

field

 

strength

 

that

 

can

 

be

 

displayed

 

on

 

a

 

spectrum

 

analyzer

 

or

 

EMI

 

receiver

 

during

 

EMI

 

testing.

  

 

Setting

 

up

 

using

 

the

 

antenna

 

is

 

described

 

in

 

section

 

6.

  

Information

 

on

 

theory

 

of

 

operation

 

is

 

given

 

in

 

section7.

 

 

Standard

 

Items

 

included

 

with

 

the

 

antenna:

 

o
