Introduction

Description

The

 

DPS

 

Power

 

Sensors

 

are

 

intended

 

for

 

use

 

in

 

coaxial

 

transmission

 

lines

 

of

 

50

 

ohm

 

nominal

 

impedance.

 

The

 

sensors

 

utilize

 

elements

 

in

 

order

 

to

 

make

 

power

 

measurements.

 

Each

 

element

 

has

 

an

 

arrow

 

on

 

it

 

that

 

represents

 

the

 

direction

 

in

 

which

 

it

 

measures

 

power.

 

The

 

elements

 

ignore

 

power

 

in

 

the

 

opposite

 

direction

 

with

 

a

 

directivity

 

of

 

at

 

least

 

25

 

dB.

 

The

 

DPS

 

series

 

can

 

make

 

power

 

measurements

 

using

 

either

 

43

 

type

 

or

 

APM/DPM

 

elements,

 

and

 

the

 

readings

 

available

 

vary,

 

based

 

on

 

which

 

elements

 

are

 

being

 

used.

Since

 

the

 

DPS

 

uses

 

two

 

elements,

 

it

 

can

 

measure

 

the

 

quality

 

of

 

the

 

system

 

by

 

comparing

 

the

 

forward

 

and

 

the

 

reflected

 

power.

 

This

 

is

 

usually

 

presented

 

in

 

the

 

form

 

of

 

VSWR

 

(voltage

 

standing

 

wave

 

ratio)

 

or

 

Return

 

Loss.

Element Types

43 Type Elements

The

 

43

 

type

 

elements

 

are

 

normally

 

used

 

to

 

measure

 

peak

 

power.

 

These

 

elements

 

can

 

measure

 

the

 

peak

 

power

 

of

 

a

 

system

 

with

 

an

 

accuracy

 

of

 

+/

8%

 

of

 

full

 

scale

 

as

 

long

 

as

 

the

 

signal

 

meets

 

the

 

following

 

requirements:

At

 

least

 

15

 

pulses

 

per

 

second

 

(PPS

Minimum

 

pulse

 

width

 

of

 

15

 

µs

 

(800

 

ns

 

if

 

frequency

 

is

 

greater

 

than

 

100

 

MHz)

Minimum

 

Duty

 

Cycle

 

of

 

0.01%

 

In

 

addition,

 

43

 

type

 

elements

 

can

 

be

 

used

 

to

 

measure

 

average

 

power

 

in

 

signals

 

with

 

a

 

peak

to

average

 

ratio

 

close

 

to

 

1,

 

like

 

a

 

CW

 

or

 

FM

 

signals.

 

In

 

these

 

cases,

 

the

 

average

 

power

 

is

 

measured

 

with

 

an

 

accuracy

 

of

 

+/

‐ 

5%

 

of

 

full

 

scale.

APM/DPM Elements

The

 

APM/DPM

 

elements

 

are

 

used

 

to

 

measure

 

true

 

average

 

power.

 

True

 

average

 

power

 

means

 

the

 

sensor

 

provides

 

equivalent

 

heating

 

power

 

of

 

the

 

signal,

 

regardless

 

of

 

modulation

 

or

 

number

 

of

 

carriers.

 

These

 

elements

 

can

 

measure

 

average

 

power

 

with

 

an

 

accuracy

 

of

 

+/

5%

 

of

 

reading

 

from

 

full

 

scale

 

down

 

to

 

2.5%

 

of

 

full

 

scale.

 

Note: 

The

 

equivalent

 

heating

 

power

 

is

 

dependent

 

on

 

the

 

duty

 

cycle

 

of

 

a

 

signal.

 

If

 

a

 

system

 

puts

 

out

 

50

 

watts

 

with

 

a

 

50%

 

duty

 

cycle,

 

the

 

APM/DPM

 

elements

 

will

 

measure

 

25

 

watts.
