Use the tables in Section 2, Microwave Path Engineering Basics, of this manual to select the 
proper free-space attenuation value (in dB) based on the estimated length of the microwave path. 
Remember to subtract both antenna gains (local and remote) from the attenuator setting.

12. Initiate a line loopback on the local TRACER 4102/4202 unit and run a test pattern from the 

connected T1 equipment. This will verify the connection between the T1 equipment and the local 
TRACER 4102/4202 unit.

13. Command a link loopback on the remote TRACER 4102/4202 unit and run a test pattern from the 

connected T1 equipment. This will verify the data path across the RF link. 

1. If possible, attach any or all of the intended T1 hardware to the TRACER 4102/4202 units using 

the same workbench setup. This step offers the perfect opportunity to configure your T1 hardware 
for proper functioning with the TRACER hardware.

2. To significantly reduce the probability of an unsuccessful field installation, resolve any remaining 

T1 equipment-to-TRACER 4102/4202 configuration issues before field installation. See pages 57 
and 57 for more information on resolving T1 interface alarm conditions.
