4.1 Conducted Emissions Test
TEST CONFIGURATION
TEST PROCEDURE
1 The equipment was set up as per the test configuration to simulate typical actual usage per the user’s manual.
The EUT is a tabletop system, a wooden table with a height of 0.8 meters is used and is placed on the
ground plane as per ANSI C63.4.
2 Support equipment, if needed, was placed as per ANSI C63.4.
3 All I/O cables were positioned to simulate typical actual usage as per ANSI C63.4.
4 The EUT received DC7.4V power from the battery.
5 All support equipments received AC power from a second LISN, if any.
6 The EUT test program was started. Emissions were measured on each current carrying line of the EUT using
a spectrum Analyzer / Receiver connected to the LISN powering the EUT. The LISN has two monitoring
points: Line 1 (Hot Side) and Line 2 (Neutral Side). Two scans were taken: one with Line 1 connected to
Analyzer / Receiver and Line 2 connected to a 50 ohm load; the second scan had Line 1 connected to a 50
ohm load and Line 2 connected to the Analyzer / Receiver.
7 Analyzer / Receiver scanned from 150 KHz to 30MHz for emissions in each of the test modes.
8 During the above scans, the emissions were maximized by cable manipulation.

a). Occupied Bandwidth: The EUT was connected to the audio signal generator and the spectrum analyzer via
the main RF connector, and through an appropriate attenuator. The EUT was controlled to transmit its
maximum power. Then the bandwidth of 99% power can be measured by the spectrum analyzer.
(b). Emission Mask B: For transmitters that are equipped with an audio low-pass filter pursuant to §90.211(a),
the power of any emission must be below the unmodulated carrier power (P) as follows:
(1) On any frequency removed from the assigned frequency by more than 50 percent, but not more than 100
percent of the authorized bandwidth: At least 25 dB.
(2) On any frequency removed from the assigned frequency by more than 100 percent, but not more than 250
percent of the authorized bandwidth: At least 35 dB.
(3) On any frequency removed from the assigned frequency by more than 250 percent of the authorized
bandwidth: At least 43 + 10 log (P) dB.
(c). Emission Mask D, 12.5 kHz channel bandwidth equipment: For transmitters designed to operate with a 12.5
kHz channel bandwidth, any emission must be attenuated below the power (P) of the highest emission
contained within the authorized bandwidth as follows:
(1) On any frequency from the center of the authorized bandwidth f0 to 5.625 kHz removed from f0: Zero dB.
(2) On any frequency removed from the center of the authorized bandwidth by a displacement frequency (fd in
kHz) of more than 5.625 kHz but no more than 12.5 kHz: At least 7.27(fd -2.88 kHz) dB.
(3) On any frequency removed from the center of the authorized bandwidth by a displacement frequency (fd in
kHz) of more than 12.5 kHz: At least 50 + 10 log (P) dB or 70 dB, whichever is the lesser attenuation.
(d). Emission Mask E—6.25 kHz or less channel bandwidth equipment. For transmitters designed to operate

4.3. Emission Mask
Applicable Standard
FCC §90.210
(b) Emission Mask B. For transmitters that are equipped with an audio low-pass filter, the power of any
emission must be attenuated below the unmodulated carrier power (P) as follows:
(1) On any frequency removed from the assigned frequency by more than 50 percent, but not more than
100 percent of the authorized bandwidth: At least 25 dB.
(2) On any frequency removed from the assigned frequency by more than 100 percent, but not more than
250 percent of the authorized bandwidth: At least 35 dB.
(3) On any frequency removed from the assigned frequency by more than 250 percent of the authorized
bandwidth: At least 43 + 10 log (P) dB.
(d) Emission Mask D—12.5 kHz channel bandwidth equipment. For transmitters designed to operate with
a 12.5 kHz channel bandwidth, any emission must be attenuated below the power (P) of the highest
emission contained within the authorized bandwidth as follows:
(1) On any frequency from the center of the authorized bandwidth f0 to 5.625 kHz removed from f0: Zero
dB.
(2) On any frequency removed from the center of the authorized bandwidth by a displacement frequency
(fd in kHz) of more than 5.625 kHz but no more than 12.5 kHz: At least 7.27(fd−2.88 kHz) dB.
(3) On any frequency removed from the center of the authorized bandwidth by a displacement frequency
(fd in kHz) of more than 12.5 kHz: At least 50 + 10 log (P) dB or 70 dB, whichever is the lesser
attenuation.
(4) The reference level for showing compliance with the emission mask shall be established using a
resolution bandwidth sufficiently wide (usually two or three times the channel bandwidth) to capture the
true peak emission of the equipment under test. In order to show compliance with the emission mask up to
and including 50 kHz removed from the edge of the authorized bandwidth, adjust the resolution
bandwidth to 100 Hz with the measuring instrument in a peak hold mode. A sufficient number of sweeps
must be measured to insure that the emission profile is developed. If video filtering is used, its bandwidth
must not be less than the instrument resolution bandwidth. For emissions beyond 50 kHz from the edge of
the authorized bandwidth, see paragraph (o) of this section. If it can be shown that use of the above
instrumentation settings do not accurately represent the true interference potential of the equipment under
test, an alternate procedure may be used provided prior Commission approval is obtained.

4.3. Radiated Spurious Emission Test
TEST APPLICABLE
According to the TIA/EIA 603 test method, and according to Section 90.210, the power of each unwanted
emission shall be less than Transmitted Power as specified below for transmitters designed to operate with
12.5 KHz channel bandwidth:
1 On any frequency removed from the center of the authorized bandwidth fo to 5.625 KHz removed from fo:
Zero dB
2 On any frequency removed from the center of the authorized bandwidth by a displacement frequency (fd in
KHz) fo of more than 5.625 KHz but no more than 12.5 KHz: At least 7.27dB
3 On any frequency removed from the center of the authorized bandwidth by a displacement frequency (fd in
KHz) fo of more than 12.5 KHz: At least 50+10 log (P) dB or 70 dB, which ever is lesser attenuation.
For transmitters designed to transmit with 6.25 KHz channel separation and equipped with an audio low-pass
filter, the power of any emission must be attenuated below the unmodulated carrier power (P) as following:
1 On any frequency from the center of the authorized bandwidth f0 to 3.0 kHz removed from f0: Zero dB.
2 On any frequency removed from the center of the authorized bandwidth by a displacement frequency (fd in
kHz) of more than 3.0 kHz but no more than 4.6 kHz: At least 30 + 16.67(fd−3 kHz) or 55 + 10 log (P) or 65 dB,
whichever is the lesser attenuation.
3 On any frequency removed from the center of the authorized bandwidth by more than 4.6 kHz: At least 55 +
10 log (P) or 65 dB, whichever is the lesser attenuation.

TEST PROCEDURE
The transmitter was placed on a wooden turntable, and it was transmitting into a non-radiating load, which
was also placed on the turntable.
The measurement antenna was placed at a distance of 3 meters from the EUT. During the tests, the
antenna height and polarization as well as EUT azimuth were varied in order to identify the maximum
level of emissions from the EUT .The test was performed by placing the EUT on 3-orthogonal axis.
The frequency range up to teeth harmonic of the fundamental frequency was investigated.
Remove the EUT and replace it with substitution antenna. A signal generator was connected to the
substitution antenna by a non-radiating cable. The absolute levels of the spurious emissions were
measured by the substitution.
Spurious emissions in dB =10 1g (TXpwr in Watts/0.001)-the absolute level Spurious attenuation limit in
dB =50+10 Log10 (power out in Watts) for EUT with a 12.5 kHz channel bandwidth.
TEST RESULTS
Modulation Type: 4FSK
Note: 1. In general, the worse case attenuation requirement shown above was applied.
2. The measurement frequency range from 30 MHz to 5 GHz.
3. *** means that the emission level is too low to be measured or at least 20 dB down than the limit.
