15.247(d) / RSS-247 5.5 and RSS GEN 8.9
Spurious Emissions - Radiated
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 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)). (note: 15.247 (b)(3) is for digital
modulation.

Follow the procedure outlined in Annex A, and B of this document.

Restricted Bands Spurious Emissions - radiated
(a) Except as shown in paragraph (d) of this section, only spurious emissions are permitted in any of
the frequency bands listed below:
(b) Except as provided in paragraphs (d) and (e) of this section, the field strength of emissions
appearing within these frequency bands shall not exceed the limits shown in §15.209. At frequencies
equal to or less than 1000 MHz, compliance with the limits in §15.209 shall be demonstrated using
measurement instrumentation employing a CISPR quasi-peak detector. Above 1000 MHz,
compliance with the emission limits in §15.209 shall be demonstrated based on the average value of
the measured emissions. The provisions in §15.35 apply to these measurements.
Measure the field strength of all transmitter spurious emissions in the restricted bands listed below.
Follow the procedure outlined in Annex A and B of this document.

Receiver Spurious Emission Limits
7.2.3.2 Radiated Measurement
All spurious emissions shall comply with the limits of Table 1.
Receiver Spurious Emissions
The receiver shall be operated in the normal receive mode near the mid-point of the band over which the
receiver is designed to operate. Unless otherwise specified in the applicable RSS, the radiated emission
measurement is the standard measurement method (with the device's antenna in place) to measure receiver
spurious emissions. Radiated emission measurements are to be performed using a calibrated open-area test
site. As an alternative, the conducted measurement method may be used when the antenna is detachable. In
such a case, the receiver spurious signal may be measured at the antenna port. If the receiver is super-
regenerative, stabilize it by coupling to it an un-modulated carrier on the receiver frequency (antenna conducted
measurement) or by transmitting an un-modulated carrier on the receiver frequency from an antenna in the
proximity of the receiver (radiated measurement). Taking care not to overload the receiver, vary the amplitude
and frequency of the stabilizing signal to obtain the highest level of the spurious emissions from the receiver. For
either method, the search for spurious emissions shall be from the lowest frequency internally generated or used
in the receiver (e.g. local oscillator, intermediate or carrier frequency), or 30 MHz, whichever is the higher, to at
least 3 times the highest tunable or local oscillator frequency, whichever is the higher, without exceeding 40
GHz.

Receiver Spurious Emission Standard
The following receiver spurious emission limits shall be complied with:
   (a) If a radiated measurement is made, all spurious emissions shall comply with the limits of
         Table 1. The resolution bandwidth of the spectrum analyzer shall be 100 kHz for spurious
         emission measurements below 1.0 GHz, and 1.0 MHz for measurements above 1.0 GHz.

Spurious RF Conducted Emissions

Use the following spectrum analyzer settings:

Span = wide enough to capture the peak level of the in-band emission and all spurious emissions
(e.g., harmonics) from the lowest frequency generated in the EUT up through the 10th harmonic.
Typically, several plots are required to cover this entire span.

RBW = 100 kHz

VBW  RBW

Sweep = auto

Detector function = peak

Trace = max hold

Allow the trace to stabilize. Set the marker on the peak of any spurious emission recorded. The level
displayed must comply with the limit specified in this Section. Submit these plots.


Spurious Radiated Emissions

This test is required for any spurious emission or modulation product that falls in a
Restricted Band, as defined in Section 15.205. It must be performed with the highest gain
of each type of antenna proposed for use with the EUT. Use the following spectrum analyzer
settings:

Span = wide enough to fully capture the emission being measured

RBW = 1 MHz for f  1 GHz, 100 kHz for f < 1 GHz

VBW  RBW

Sweep = auto

Detector function = peak

Trace = max hold

Follow the guidelines in ANSI C63.4-2003 with respect to maximizing the emission by rotating the
EUT, measuring the emission while the EUT is situated in three orthogonal planes (if appropriate),
adjusting the measurement antenna height and polarization, etc. A pre-amp and a high pass filter are
required for this test, in order to provide the measuring system with sufficient sensitivity. Allow the
trace to stabilize. The peak reading of the emission, after being corrected by the antenna factor,
cable loss, pre-amp gain, etc., is the peak field strength, which must comply with the limit specified in
Section 15.35(b). Submit this data.

Now set the VBW to 10 Hz, while maintaining all of the other instrument settings. This peak level,

                                                                                             FCC-1601-006

once corrected, must comply with the limit specified in Section 15.209. If the dwell time per channel
of the hopping signal is less than 100 ms, then the reading obtained with the 10 Hz VBW may be
further adjusted by a "duty cycle correction factor", derived from 20log(dwell time/100 ms), in an effort
to demonstrate compliance with the 15.209 limit. Submit this data.

If the emission on which a radiated measurement must be made is located at the edge of the
authorized band of operation, then the alternative "marker-delta" method, listed at the end of this
document, may be employed.

Alternative Test Procedures

If antenna conducted tests cannot be performed on this device, radiated tests to show compliance
with the peak output power limit specified in Section 15.247(b) (2) and the spurious RF conducted
emission limit specified in Section 15.247(d) are acceptable. A pre-amp, and, in the latter case, a
high pass filter, are required for the following measurements.

1) Calculate the transmitter's peak power using the following equation:
                                                      30PG
                                             E
                                                       d
Where: E is the measured maximum fundamental field strength in V/m, utilizing a RBW  the 20 dB
bandwidth of the emission, VBW > RBW, peak detector function. Follow the procedures in C63.4-
2003 with respect to maximizing the emission.

G is the numeric gain of the transmitting antenna with reference to an isotropic radiator.

d is the distance in meters from which the field strength was measured.

P is the power in watts for which you are solving:

                                              P
                                                     E  d  2
                                                      30G
2) To demonstrate compliance with the spurious RF conducted emission requirement of Section
15.247(d), use the following spectrum analyzer settings:

Span = wide enough to fully capture the emission being measured

RBW = 100 kHz

VBW  RBW

Sweep = auto

Detector function = peak

Trace = max hold

Measure the field strength of both the fundamental emission and all spurious emissions with these
settings. Follow the procedures in C63.4-2003 with respect to maximizing the emissions. The
measured field strength of all spurious emissions must be below the measured field strength of the
fundamental emission by the amount specified in Section 15.247(d). Note that if the emission falls in
a Restricted Band, as defined in Section 15.205, the procedure for measuring spurious radiated
emissions, listed above, must be followed.

Marker-Delta Method

In making radiated band-edge measurements, there can be a problem obtaining meaningful data
since a measurement instrument that is tuned to a band-edge frequency may also capture some
in-band signals when using the resolution bandwidth (RBW) required by measurement procedure
ANSI C63.4-2003 (hereafter C63.4). In an effort to compensate for this problem, we have developed
the following technique for determining band-edge compliance.

STEP 1) Perform an in-band field strength measurement of the fundamental emission using the RBW
and detector function required by C63.4 and our Rules for the frequency being measured. For example,
for a device operating in the 902-928 MHz band under Section 15.249, use a 120 kHz RBW with a
CISPR QP detector (a peak detector with 100 kHz RBW may alternatively be used). For transmitters
operating above 1 GHz, use a 1 MHz RBW, a 1 MHz VBW, and a peak detector (as required by Section
15.35). Repeat the measurement with an average detector (i.e., 1 MHz RBW with 10 Hz VBW). Note:
For pulsed emissions, other factors must be included. Please contact the FCC Lab for details if the
emission under investigation is pulsed. Also, please note that radiated measurements of the
fundamental emission of a transmitter operating under 15.247 are not normally required, but they are
necessary in connection with this procedure.

STEP 2) Choose a spectrum analyzer span that encompasses both the peak of the fundamental
emission and the band-edge emission under investigation. Set the analyzer RBW to 1% of the total
span (but never less than 30 kHz) with a video bandwidth equal to or greater than the RBW. Record
the peak levels of the fundamental emission and the relevant band-edge emission (i.e., run several
sweeps in peak hold mode). Observe the stored trace and measure the amplitude delta between the
peak of the fundamental and the peak of the band-edge emission. This is not a field strength
measurement; it is only a relative measurement to determine the amount by which the emission drops
at the band-edge relative to the highest fundamental emission level.

STEP 3) Subtract the delta measured in step (2) from the field strengths measured in step (1). The
resultant field strengths (CISPR QP, average, or peak, as appropriate) are then used to determine
band-edge compliance as required by Section 15.205.

STEP 4) The above "delta" measurement technique may be used for measuring emissions that are up
to two "standard" bandwidths away from the band-edge, where a "standard" bandwidth is the bandwidth
specified by C63.4 for the frequency being measured. For example, for band-edge measurements in
the restricted band that begins at 2483.5 MHz, C63.4 specifies a measurement bandwidth of at least 1
MHz. Therefore you may use the "delta" technique for measuring emissions up to 2 MHz removed from
the band-edge. Radiated emissions that are removed by more than two “standard” bandwidths must be
measured in the conventional manner.

Field Strength Measurement Procedure


This test measures the field strength of radiated emissions using a spectrum analyzer and a receiving
antenna in accordance with ANSI C63.4-2003. During the test, the EUT is to be placed on a non-
conducting support at 80 cm above the horizontal ground plane of the OATS. The horizontal distance
between the antenna and the EUT is to be 3 meters. The bandwidths used shall be; 200 Hz from 9
kHz to 150 kHz, 9 kHz from 150 kHz to 30 MHz, 120 kHz from 30 MHz to 1000 MHz, and 1 MHz from
1 GHz to 40 GHz, with the detector set to peak hold.

1) The antenna correction factor, preamplifier gain (if the preamplifier is installed), and cable loss may
be stored in tables in the EMC analyzer and the level at the analyzer is then the corrected level in
dbuV/m. Otherwise it is calculated externally.
2) Monitor the frequency range of interest at a fixed antenna height and EUT azimuth.
3) If appropriate, manipulate the system cables to produce the highest amplitude signal relative to the
limit. Note the amplitude and frequency of the suspect signal.
4) Rotate the EUT 360° to maximize the suspected highest amplitude signal. If the signal or another
at a different frequency is observed to exceed the previously noted highest amplitude signal by 1 dB
or more, go back to the azimuth and repeat step 3). Otherwise, orient the EUT azimuth to repeat the
highest amplitude observation and proceed.
5) Move the antenna over its fully allowed range of travel to maximize the suspected highest
amplitude signal. If the signal or another at a different frequency is observed to exceed the previously
noted highest amplitude signal by 1 dB or more, return to step 3) with the antenna fixed at this height.
Otherwise, move the antenna to the height that repeats the highest amplitude observation and
proceed.
6) Change the polarity of the antenna and repeat step 3), step 4), and step 5). Compare the resulting
suspected highest amplitude signal with that found for the other polarity. Select and note the higher of
the two signals.
7) The final maximized level displayed on the EMC analyzer is the field strength.

Section 15.247(b) (3): For systems using digital modulation in the 902-928 MHz, 2400-2483.5 MHz, and 5725-5850 MHz
bands: 1 Watt. As an alternative to a peak power measurement, compliance with the one Watt limit can be based on a
measurement of the maximum conducted output power. Maximum Conducted Output Power is defined as the total transmit
power delivered to all antennas and antenna elements averaged across all symbols in the signaling alphabet when the
transmitter is operating at its maximum power control level. Power must be summed across all antennas and antenna
elements. The average must not include any time intervals during which the transmitter is off or is transmitting at a reduced
power level. If multiple modes of operation are possible (e.g., alternative modulation methods), the maximum conducted
output power is the highest total transmit power occurring in any mode.

917-114 Report and Order, Released: April 10, 1997:
Section 15.247(c): Spurious emissions. The following tests are required:

(1) RF antenna conducted test: Set RBW = 100 kHz, Video bandwidth (VBW) > RBW, scan up through 10th harmonic. All
harmonics/spurs must be at least 20 dB down from the highest emission level within the authorized band as measured with a 100
kHz RBW.
(2) Radiated emission test: Applies to harmonics/spurs that fall in the restricted bands listed in Section 15.205. The maximum
permitted average field strength is listed in Section 15.209. A pre-amp (and possibly a high-pass filter) is necessary for this
measurement. For measurements above 1 GHz, set RBW = 1 MHz, VBW = 10 Hz, Sweep: Auto. If the emission is pulsed, modify
the unit for continuous operation, use the settings shown above, then correct the reading by subtracting the peak-average correction
factor, derived from the appropriate duty cycle calculation. See Section 15.35(b) and (c).

§15.33 Frequency range of radiated measurements.
(a) For an intentional radiator, the spectrum shall be investigated from the lowest radio frequency signal generated in the device,
without going below 9 kHz, up to at least the frequency shown in this paragraph:
(1) If the intentional radiator operates below 10 GHz: to the tenth harmonic of the highest fundamental frequency or to 40 GHz,
whichever is lower.

Section 15.33 (b) - Frequency range of radiated measurements. For unintentional radiators: see part. (9kHz or lowest
generated to 5GHz or 5th harmonic)

Section 15.35 Measurement detector functions and bandwidths. - The conducted and radiated emission limits shown in this part
are based on the following, unless otherwise specified elsewhere in this part:

(a) …( (a) does not apply to this report)

(b) Unless otherwise specified, on any frequency or frequencies above 1000 MHz, the radiated emission limits are based on the
use of measurement instrumentation employing an average detector function. Unless otherwise specified, measurements above
1000 MHz shall be performed using a minimum resolution bandwidth of 1 MHz. When average radiated emission measurements
are specified in this part, including average emission measurements below 1000 MHz, there also is a limit on the peak level of the
radio frequency emissions. Unless otherwise specified, e.g., see §§15.250, 15.252, 15.255, and 15.509-15.519, the limit on peak
radio frequency emissions is 20 dB above the maximum permitted average emission limit applicable to the equipment under test.
This peak limit applies to the total peak emission level radiated by the device, e.g., the total peak power level. Note that the use of a
pulse desensitization correction factor may be needed to determine the total peak emission level. The instruction manual or
application note for the measurement instrument should be consulted for determining pulse desensitization factors, as necessary.

(c) Unless otherwise specified, e.g. §15.255(b), when the radiated emission limits are expressed in terms of the average value of
the emission, and pulsed operation is employed, the measurement field strength shall be determined by averaging over one
complete pulse train, including blanking intervals, as long as the pulse train does not exceed 0.1 seconds. As an alternative
(provided the transmitter operates for longer than 0.1 seconds) or in cases where the pulse train exceeds 0.1 seconds, the
measured field strength shall be determined from the average absolute voltage during a 0.1 second interval during which the field
strength is at its maximum value. The exact method of calculating the average field strength shall be submitted with any application
for certification or shall be retained in the measurement data file for equipment subject to Declaration of Conformity or verification.

RSS-GEN 4.9 Transmitter Unwanted Emissions:
The search for unwanted emissions shall be from the lowest frequency internally generated or used in the device (local oscillator,
intermediate or carrier frequency), or from 30 MHz, whichever is the lower, to the 5th harmonic of the highest frequency generated
without exceeding 40 GHz.
