Transmit Threshold Control 

The

 

Transmit

 

Threshold

 

Control

 

feature

 

enables

 

the

 

user

 

to

 

change

 

the

 

signal

 

level

 

threshold

 

at

 

which

 

the

 

Xtender

 

automatically

 

switches

 

from

 

its

 

default

 

receive

 

state

 

to

 

its

 

transmit

 

state.

 

By

 

setting

 

a

 

higher

 

transmit

 

threshold

 

control

 

value

 

(higher

 

sensitivity),

 

the

 

user

 

can

 

help

 

facilitate

 

more

 

accurate

 

transmit/receive

 

state

 

switching.

  

Note:

 

If

 

the

 

Xtender

 

is

 

exhibiting

 

false

 

transmit

 

switch

 

triggering,

 

it

 

is

 

recommended

 

to

 

set

 

a

 

lower

 

transmit

 

threshold

 

control

 

value.

 

The

 

“STAT?”

 

command

 

can

 

be

 

used

 

to

 

display

 

the

 

current

 

Transmit

 

Threshold

 

Control

 

value.

 

The

 

“TRLVL

xxxx

”

 

command

 

is

 

used

 

to

 

change

 

the

 

setting

 

of

 

the

 

Transmit

 

Threshold

 

Control

 

value.

 

The

 

Transmit

 

Threshold

 

Control

 

settings

 

are

 

defined

 

as:

 

 

0000

 

=

 

lowest

 

Transmit

 

Threshold

 

Control

 

value,

 

lowest

 

transmit

 

detection

 

sensitivity.

 

 

4095

 

=

 

highest

 

Transmit

 

Threshold

 

Control

 

value,

 

greatest

 

transmit

 

detection

 

sensitivity.

 

 

A

 

Transmit

 

Threshold

 

Control

 

value

 

of

 

1800

 

sets

 

the

 

threshold

 

to

 

approximately

 

0

 

dBm.

 

 

Note:

 

Factory

 

default

 

setting

 

is

 

1800

 

(~0

 

dBm

 

threshold).
