§15.247(d) –Band-Edge & Unwanted Emissions into Non-
Restricted Frequency Bands
1.
In any 100 kHz bandwidth outside the frequency band in which the spread spectrum or digitally
modulated intentional radiator is operating, the radio frequency power that is produced by the intentional
radiator shall be at least 20 dB below that in the 100 kHz bandwidth within the band that contains the highest
level of the desired power, based on either an RF conducted or a radiated measurement, provided the
transmitter demonstrates compliance with the peak conducted power limits. If the transmitter complies with
the conducted power limits based on the use of RMS averaging over a time interval, as permitted under
paragraph (b)(3) of this section, the attenuation required under this paragraph shall be 30 dB instead of 20 dB.
Attenuation below the general limits specified in §15.209(a) is not required. In addition, radiated emissions
which fall in the restricted bands, as defined in §15.205(a), must also comply with the radiated emission
limits specified in §15.209(a) (see §15.205(c))

Tested By : Back Huang
Requirement(s):
Band-Edge Measurements
An additional consideration when performing conducted measurements of restricted band emissions is that unwanted
emissions radiating from the EUT cabinet, control circuits, power leads, or intermediate circuit elements will likely go
undetected in a conducted measurement configuration. To address this concern, a radiated test shall be performed to
ensure that emissions emanating from the EUT cabinet (rather than the antenna port) also comply with the applicable
limits.
For these cabinet radiated spurious emission measurements the EUT transmit antenna may be replaced with a
termination matching the nominal impedance of the antenna. Procedures for performing radiated measurements are
specified in ANSI C63.10. All detected emissions shall comply with the applicable limits.
Procedures: (Radiated Method Only)
1.
Check the calibration of the measuring instrument using either an internal calibrator or a known signal from an
external generator.
2.
Position the EUT on the rotated table inside the anechoic chamber without connection to measurement instrument.
Turn on the EUT and make it operate in transmitting mode. Then set it to Low Channel and High Channel within
its operating range, and make sure the instrument is operated in its linear range. Repeat above procedures until all
measured frequencies were complete.
3.
Set band RBW=1MHz, VBW=3MHz with a convenient frequency span from band edge.
4.
Find the highest point in edge frequency,and then calculated results.
5.
Repeat above procedures until all measured frequencies were complete.
Test Result: Pass.
