LEDs and Fault Alarms 

 

 

G-WAVE amplifiers are 
shipped from the factory 
with 30 dB of attenuation 
dialed in. Units are not 
shipped with full gain to 
ensure input signal does 
not overdrive the ALC 
limitation of the unit.

 

 

If the attenuation rotary 
switch is dialed to 30 – 
This indicates the unit has 
30 dB of attenuation and 
is running on minimum 
gain potential of the 
system.

 

 

 
 
 

 

*Oscillation

 

Detect

 

(ODSC)

 

and

 

MOBILE

 

are

 

optional

 

features

 

that

 

may

 

be

 

populated

 

into

 

the

 

O26

 

pin

out.

 

These

 

alarm

 

contacts

 

are

 

not

 

included

 

as

 

a

 

standard

 

and

 

must

 

be

 

requested

 

at

 

time

 

of

 

order.

 

To add gain back to the 
system, dial back the 
rotary switch, slowly, (28, 
26, 24, 22…) until the 
Downlink ALC LED turns 
on. This indicates the unit 
has reached maximum 
output power (per unit’s 
specification).

 

 

At this point, dial one step 
of attenuation back into 
the unit to turn the 
Downlink ALC LED off
At this point the Downlink 
path of the system has 
been commissioned.

 

 

Repeat the above 
procedure on the Uplink 
path.

 

 
 
 

 

Warning!

 

Input Signal Level greater than -30 

dBm may cause damage to the 

system.
