Wireless Extenders designed the YX510 to meet BOTH the needs of the wireless carrier and the wireless consumer. The YX510 is available in three model variants, YX510-CEL, YX510-PCS, and a dual band version YX510-PCS-CEL. All models utilize the same PCB, which is fully populated for the YX510-PCS-CEL model to offer dual band capabilities. For the single band model variants the PCB portion which is not utilized is depopulated. This report addresses the YX510-PCS operation only. An additional report is available for the YX510-CEL operation. Manufacturer Information: Wi-Ex One Meca Way Norcross, GA 30093 Detailed photographs of the EUT are filed separately with this filing. 1.3 Test Methodology and Considerations The EUT was configured and tested utilizing the maximum input drive level resulting in maximum gain conditions for all tests. If the maximum input drive level is exceeded, internal attenuators are activated to produce a level RF output and eliminate the device from operating beyond the maximum RF output power that is below the saturated RF output power. For unintentional radiated emissions measurements the EUT was configured with one port loaded with a 50 Ohm non-radiating load and the other port loaded with a representative antenna. Both ports could not be loaded with representative antennas within the test environment due to the isolation required between antennas and the fact the device would receive and transmit any received signals via the antennas. Both the uplink and downlink ports were evaluated with antennas attached and the worst case provided in this report.
