4.5Measurement Results Explanation Example
4.5.1 For conducted test items:
The offset level is set in the spectrum analyzer to compensate the RF cable loss and attenuator between EUT
conducted output port and spectrum analyzer. With the offset compensation, the spectrum analyzer reading level
is exactly the EUT RF output level.
The spectrum analyzer offset is derived from RF cable loss and attenuator factor.
Offset = RF cable loss + attenuator factor.
4.5.2 For radiated band edges and spurious emission test:
E = EIRP – 20log D + 104.8
where:
E = electric field strength in dBμV/m,
EIRP = equivalent isotropic radiated power in dBm
D = specified measurement distance in meters.
EIRP= Measure Conducted output power Value (dBm) + Maximum transmit antenna gain (dBi) + the appropriate
maximum ground reflection factor (dB)

FCC §15.203 & 15.247(b); RSS-247, 5.4 (6)
An intentional radiator shall be designed to ensure that no antenna other than that furnished by the responsible
party shall be used with the device. The use of a permanently attached antenna or of an antenna that uses a
unique coupling to the intentional radiator shall be considered sufficient to comply with the provisions of this section.
The manufacturer may design the unit so that a broken antenna can be replaced by the user, but the use of a
standard antenna jack or electrical connector is prohibited. This requirement does not apply to carrier current
devices or to devices operated under the provisions of § 15.211, § 15.213, § 15.217, § 15.219, or § 15.221. Further,
this requirement does not apply to intentional radiators that must be professionally installed, such as perimeter
protection systems and some field disturbance sensors, or to other intentional radiators which, in accordance with
§ 15.31(d), must be measured at the installation site. However, the installer shall be responsible for ensuring that
the proper antenna is employed so that the limits in this part are not exceeded.
If directional gain of transmitting antennas is greater than 6 dBi, the power shall be reduced by the same level in
dB comparing to gain minus 6 dBi. For the fixed point-to-point operation, the power shall be reduced by one dB for
every 3 dB that the directional gain of the antenna exceeds 6 dBi. The use of a permanently attached antenna or
of an antenna that uses a unique coupling to the intentional radiator shall be considered sufficient to comply with
the FCC rule.

5.2Output Power
5.2.1 Test Limit
FCC § 15.247(b); RSS-247, 5.4 (4)
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.
5.2.2 Test Setup
See section 4.4.1 for test setup description for the antenna port. The photo of test setup please refer to ANNEX B.
5.2.3 Test Procedure
Maximum peak conducted output power
The maximum peak conducted output power may be measured using a broadband peak RF power meter. The
power meter shall have a video bandwidth that is greater than or equal to the DTS bandwidth and shall utilize a
fast-responding diode detector.
Maximum conducted (average) output power (Reporting Only)
a) As an alternative to spectrum analyzer or EMI receiver measurements, measurements may be performed
using a wideband RF power meter with a thermocouple detector or equivalent if all of the conditions listed below
are satisfied.
1) The EUT is configured to transmit continuously, or to transmit with a constant duty factor.
2) At all times when the EUT is transmitting, it shall be transmitting at its maximum power control level.
3) The integration period of the power meter exceeds the repetition period of the transmitted signal by at least a
factor of five.
b) If the transmitter does not transmit continuously, measure the duty cycle (x) of the transmitter output signal as
described in Section 6.0.
c) Measure the average power of the transmitter. This measurement is an average over both the on and off
periods of the transmitter.
d) Adjust the measurement in dBm by adding 10log (1/x), where x is the duty cycle to the measurement result.
Measurements of duty cycle
The zero-span mode on a spectrum analyzer or EMI receiver if the response time and spacing between bins on
the sweep are sufficient to permit accurate measurements of the on and off times of the transmitted signal.
Set the center frequency of the instrument to the center frequency of the transmission.

Set RBW ≥ OBW if possible; otherwise, set RBW to the largest available value.
Set VBW ≥ RBW. Set detector = peak or average.
The zero-span measurement method shall not be used unless both RBW and VBW are > 50/T and the number of
sweep points across duration T exceeds 100. (For example, if VBW and/or RBW are limited to 3 MHz, then the
zero-span method of measuring duty cycle shall not be used if T ≤ 16.7 microseconds.)

5.36dB Bandwidth
5.3.1 Limit
FCC §15.247(a); RSS-GEN, 6.6
Make the measurement with the spectrum analyzer's resolution bandwidth (RBW) = 100 kHz. In order to make an
accurate measurement, set the span greater than RBW. The 6 dB bandwidth must be greater than 500 kHz.
5.3.2 Test Setup
See section 4.4.1 for test setup description for the antenna port. The photo of test setup please refer to ANNEX B.
5.3.3 Test Procedure
Use the following spectrum analyzer settings:
Set RBW = 100 kHz.
Set the video bandwidth (VBW) ≥ 3 RBW.
Detector = Peak.
Trace mode = max hold.
Sweep = auto couple.
Allow the trace to stabilize.
Measure the maximum width of the emission that is constrained by the frequencies associated with the two
outermost amplitude points (upper and lower frequencies) that are attenuated by 6 dB relative to the maximum
level measured in the fundamental emission.
