2. RF measurement of the radio. This test measures the RF output of each WRE. The WRE under this test
will be placed in continuous transmit mode (5 sec on/5 Sec off). Measurement will be accomplished using
the RF Power Meter Option of the Anritsu Site Mater 251C. This reading will be recorded in the WRE RF
Power Measurement Column of the Test Record Form in Annex TR. This value together with the
minimum specified path loss for any configuration and antenna gain will be used to determine compliance
with the RF output requirements. The configuration of this test is outlined in figure 5.2 below. The 1.5
meter test cable loss will be measured prior to testing and this loss will be added to the RF power output.
