APPENDIX C: INSTALLING THE REPEATER IN
A LABORATORY SETTING
If you want to test the performance of the repeater prior to actually installing it in the
field, you can do so in a laboratory setting as follows:
Note
In the event that the antennas are not connected, terminate the Base and Mobile
connectors with a 30 dB attenuator or 50 Ohm load.
This will prevent a regressing
signal from damaging the test equipment.
Use 30db attenuators with a power rating of at least 50W at the Mobile connector
and at least 10W at the Base connector.
Connect a Power Supply voltage (90 to 260 VAC) to the Repeater’s AC
connector (refer to the test diagram below).

Connect an RF Generator to the Repeater’s Base connector
Inject an RF Signal from the connected RF Generator to the downlink route
through the Base connector.
Connect a Spectrum Analyzer to the Mobile connector.
Test the repeater’s RF performance.
