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 marked 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
and at least 10W at the Base connector.
1. Connect the power supply. Connect a supplied voltage in the range of 90 to 260
VAC to the Repeater's AC power connector. (See the test diagram below.)
2. Inject an RF Signal from the connected RF Generator to the repeater's downlink
route (Base connector). Inject a Spectrum Analyzer to the Mobile connector.
3. Test the repeater's RF performance.

4. Test the Repeater's Uplink route by connecting the RF Signal Generator to the
Mobile connector and a Spectrum Analyzer to the Base connector. (See the test
setup diagram below.)
