EMC Test Data Client: Askey Computer Corporation Job Number: J76020 T-Log Number: T76037 Model: WPA5151 Account Manager: Dean Eriksen Contact: Jerry Chan Standard: FCC Part 15, RSS 210 Class: N/A Maximum Permissible Exposure Test Specific Details The objective of this test session is to perform final qualification testing of the EUT with respect to the Objective: specification listed above. Date of Test: 7/31/2009 Test Engineer: Mark Hill General Test Configuration Calculation uses the free space transmission formula: S = (PG)/(4 πd 2) Where: S is power density (W/m2), P is output power (W), G is antenna gain relative to isotropic, d is separation distance from the transmitting antenna (m). Summary of Results Device complies with Power Density requirements at Yes 20cm separation: Maximum Power Density (mW/cm^2) @ 20cm 0.018 Modifications Made During Testing No modifications were made to the EUT during testing Deviations From The Standard No deviations were made from the requirements of the standard.
