5. Enter the required attenuation value and click OK to close the pop-up screen and to make
the changes take effect.
6. Verify that the appropriate RF output signal level appears in the RF Output Power field
(see Figure 3-9). This is primarily a reference value and should not take the place of
external test equipment when determining the power level of the composite RF output
signal. Depending on the modulation type and number of channels, the EMS software may
report a power level that is higher or lower (± 3 dB) than the actual RF output signal.
Note: To comply with Maximum Permissible Exposure (MPE) requirements, the
maximum composite output from the antenna cannot exceed 1000 Watts EIRP and the
antenna must be permanently installed in a fixed location that provides at least 6 meters
(20 feet) of separation from all persons.
