EMC Test Data Client: Motorola Job Number: J87247 T-Log Number: T87276 Model: VAP2500 Account Manager: Christine Krebill Contact: Rob Linebarger Standard: FCC 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: 8/3/2012 Test Engineer: Mark Hill General Test Configuration Calculation uses the free space transmission formula: S = (PG)/(4 πd2) 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: If not, required separation distance (in cm): - 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.
