TEST PROCEDURE
The EUT was modulated by 2.5kHz sine wave audio signal; the level of the audio signal employed is
16dB greater than that necessary to produce 50% of rated system deviation.
Spectrum set as follow:
Centre frequency = fundamental frequency, span=50kHz for 12.5kHz channel spacing,
RBW=100Hz, VBW=300Hz, Sweep = auto,
Detector function = peak, Trace = max hold

5.3. Emission Mask
Transmitters used in the radio services governed by this part must comply with the emission masks
outlined in this section.
LIMIT
FCC Part 95.2779,FCC Part 2.1049
(a) Emission masks. Emission masks applicable to transmitting equipment in the MURS are defined by the
requirements in the following table. The numbers in the paragraphs column refer to attenuation
requirement rule paragraph numbers under paragraph (b) of this section. The words “audio filter” refer to
the audio filter described in §95.2775.
(1) Each MURS transmitter type that transmits F3E or G3E emissions on 154.570 MHz or 154.600 MHz and
incorporates an audio filter satisfying the requirements of §95.2775 in its design may comply with the less
stringent unwanted emissions attenuation requirements set forth in paragraphs (b)(3), (4), and (7) of this
section.
(2) Each MURS transmitter type that transmits on 154.570 MHz or 154.600 MHz, but does not incorporate an
audio filter satisfying the requirements of §95.2775 in its design, must comply with the unwanted emissions
attenuation requirements set forth in paragraphs (b)(5) through (7) of this section.
(b) Attenuation requirements. The power of unwanted emissions must be attenuated below the transmitter
output power in Watts (P) by at least:
(1) 7.27(fd−2.88 kHz) dB on any frequency removed from the channel center frequency by a displacement
frequency (fd in kHz) that is more than 5.625 kHz, but not more than 12.5 kHz.
(2) 50 + 10 log (P) dB or 70 dB, whichever is the lesser attenuation, on any frequency removed from the
channel center frequency by more than 12.5 kHz.
(3) 25 dB on any frequency removed from the channel center frequency by more than 10 kHz, but not more
than 20 kHz.
(4) 35 dB on any frequency removed from the channel center frequency by more than 20 kHz, but not more
than 50 kHz.
(5) 83 log (fd ÷ 5) dB on any frequency removed from the center of the authorized bandwidth by a
displacement frequency (fd in kHz) that is more than 5 kHz, but not more than 10 kHz.
(6) 29 log (fd2 ÷ 11) dB or 50 dB, whichever is the lesser attenuation on any frequency removed from the

TEST PROCEDURE
1. Standard Transmitter Load with a 50Ω input impedance and an output impedance matched to the test
equipment.
2. EUT was placed on a 0.8 meter high non-conductive stand at a 3 meter test distance from the receive
antenna. A receiving antenna was placed on the antenna mast 3 meters from the EUT for emission
measurements. The height of receiving antenna is 1. 0 m. Detected emissions were maximized at each
frequency by rotating the EUT through 360°and adjusting the receiving antenna polarization. The radiated
emission measurements of all transmit frequencies in six channels were measured with peak detector.
3. A log-periodic antenna or double-ridged waveguide horn antenna shall be substituted in place of the EUT.
The log-periodic antenna will be driven by a signal generator and the level will be adjusted till the same
power value on the spectrum analyzer or receiver. The level of the spurious emissions can be calculated
through the level of the signal generator, cable loss, the gain of the substitution antenna and the reading
of the spectrum analyzer or receiver.
4. The EUT is then put into continuously transmitting mode at its maximum power level during the test.Set
Test Receiver or Spectrum RBW=1MHz,VBW=3MHz for above 1GHz and RBW=100kHz,VBW=300kHz
for 30MHz to 1GHz, And the maximum value of the receiver should be recorded as (Pr).
5. The EUT shall be replaced by a substitution antenna. In the chamber, an substitution antenna for the
frequency band of interest is placed at the reference point of the chamber. An RF Signal source for the
frequency band of interest is connected to the substitution antenna with a cable that has been constructed
to not interfere with the radiation pattern of the antenna. A power (PMea) is applied to the input of the
substitution antenna, and adjust the level of the signal generator output until the value of the receiver
reach the previously recorded (Pr). The power of signal source (PMea) is recorded. The test should be
performed by rotating the test item and adjusting the receiving antenna polarization.
6. A amplifier should be connected to the Signal Source output port. And the cable should be connect
between the Amplifier and the Substitution Antenna. The cable loss (Pcl) ,the Substitution Antenna Gain
(Ga) and the Amplifier Gain (PAg) should be recorded after test.
The measurement results are obtained as described below:
Power(EIRP)=PMea- PAg - Pcl - Ga
We used SMF100A micowave signal generator which signal level can up to 33dBm,so we not used power
Amplifier for substituation test; The measurement results are amend as described below:
Power(EIRP)=PMea- Pcl - Ga
7. This value is EIRP since the measurement is calibrated using an antenna of known gain (2.15 dBi) and
known input power.
8. ERP can be calculated from EIRP by subtracting the gain of the dipole, ERP = EIRP-2.15dBi.
