6      Out of Band Emissions at Antenna Terminals
       FCC 22.901(d), 22.917, 24.238(a)

Out of Band Emissions:
The mean power of emissions must be attenuated below the mean power of the
unmodulated carrier (P) on any frequency outside the frequency band by at least
(43 + 10 log P) dB. The out of band emission limit translates to a worst case absolute
limit of -13dBm in this case.

6.1 Test Procedure
The RF output of the transmitter was connected to a spectrum analyzer through a
calibrated coaxial cable. Sufficient scans were taken to show the out-of-band emissions,
if any, up to 10th harmonic. The EUT was scanned for spurious emissions from 1MHz to
20GHz with sufficient bandwidth and video resolution. Data plots are included. Multiple
sweeps were recorded in maximum hold mode using a peak detector to ensure that the
worst-case emissions were captured.
