8 Transmit Power 47CFR25.50(h) The equipment was configured as per figure 1 and the measurements were made conducted using the RMS detector of the FSQ which was gated to only perform measurement during the ON time of the transmitter. The transmit power of each port was measured individually, summed and then converted to EIRP by adding 18.0 dBi. Since the channel bandwidth of the transmitter is greater than both 6.0 and 5.5 MHz, and the EIRP is well within maximum permitted, a conservative maximum EIRP limit for Airsynergy is 33dBW will be used.

Markers were placed on the plots in figure 4 to show where power level for individual ports was failing the limit and also where the level had dropped to approximately -20 dBm/MHz. The power in these 1MHz bands near to the band edge were remeasured using the Spectrum Analyser’s integrated Channel Power Measurement capability with measurement gated such that it was only made during the on time of the transmitter. Power from each port in each band of interest was measured, summed linearly and compared against limit of -13.0 dBm.

11 Conducted Spurious Emissions Initial scan was performed on top channel using peak detector and max-hold on port RF-3 which had the highest transmit power. As no emissions or harmonics of note were found, determination of total spurious emission for comparing with limit line was done by adding 10 log (2), or 3dB to the emission level measured on port RF-3.
