12A-1A-2A-10A-4A-13A-11A-3A-6A-14A-8A-5A-15A-7A-9A-16A12B-1B-2B-10B-4B-13B-11B-3B-6B-14B-8B-5B-15B-7B-9B-16B12C-1C-2C-10C-4C-13C-11C-3C-6C-14C-8C-5C-15C-7C-9C-16C12D-1D-2D-10D-4D-13D-11D-3D-6D-14D-8D-5D-15D-7D-9D-16D-
Receiver input
bandwidth
These 4 hopping sequences will be used alternatively.
The receiver bandwidth is equal to the transmitted signal bandwidth. The receiver IF
bandwidth is 4.5MHz. When the system is set at receiver mode, the VCO frequency
will automatically be set at the desired frequency – 4.5MHz (RX VCO frequency = RX
VCO frequency – 4.5MHz). When the system is set at TX mode, the VCO
frequency will be automatically set at the desired frequency (TX VCO frequency).
As the transmitter (BU) will generate the hopping sequence and send this information
to the associated receiver (PU). The receiver will shift frequency according to this
information. So the frequency channels of the system can be synchronized.

based on either an RF conducted, provided the transmitter demonstrates compliance with the peak
conducted power limits.
8.7.3
Test Configuration
Test according to clause 7.1 radio frequency test setup 1
8.7.4
Test Procedure
The transmitter output (antenna port) was connected to the spectrum analyzer
 Reference level measurement
Establish a reference level by using the following procedure:
Set instrument center frequency to DSS channel center frequency.
Set Span = approximately 5 times the 20 dB bandwidth, centered on a hopping channel.
Set the RBW = 100 kHz. Set the VBW ≥ 3 x RBW.
Set Detector = peak. Set Sweep time = auto couple.
Set Trace mode = max hold. Allow trace to fully stabilize.
Use the peak marker function to determine the maximum Maximum conduceted level.
Note that the channel found to contain the maximum conduceted level can be used to establish the
reference level.
 Band-edge Compliance of RF Conducted Emissions
Use the following spectrum analyzer settings:
Span = wide enough to capture the peak level of the emission operating on the channel closest to the
band-edge, as well as any modulation products which fall outside of the authorized band of operation
Set RBW  1% of the span=100kHz Set VBW  RBW
Set Sweep = auto Set Detector function = peak Set Trace = max hold
Allow the trace to stabilize. Set the marker on the emission at the bandedge, or on the highest modulation
product outside of the band, if this level is greater than that at the bandedge. Enable the marker-delta
function, then use the marker-to-peak function to move the marker to the peak of the in-band emission.
The marker-delta value now displayed must comply with the limit specified in this Section.
Now, using the same instrument settings, enable the hopping function of the EUT. Allow the trace to
stabilize. Follow the same procedure listed above to determine if any spurious emissions caused by the
hopping function also comply with the specified limit.
 Conduceted Spurious RF Conducted Emission
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.(30MHz to
25GHz). Set RBW = 100 kHz
Set VBW  RBW
Set Sweep = auto
Set Detector function = peak Set Trace = max hold

Test Procedure
This test is required for any spurious emission 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:
For Above 1GHz:
The EUT was placed on a turn table which is 0.1m above ground plane.
Maximum procedure was performed on the highest emissions to ensure EUT compliance.
Span = wide enough to fully capture the emission being measured
RBW = 1 MHz
VBW  RBW
Sweep = auto

Detector function = peak
Trace = max hold
For Below 1GHz:
The EUT was placed on a turn table which is 0.1m above ground plane.
Maximum procedure was performed on the highest emissions to ensure EUT compliance.
Span = wide enough to fully capture the emission being measured
RBW = 100 kHz for
VBW  RBW
Sweep = auto
Detector function = peak
Trace = max hold
For Below 30MHz:
The EUT was placed on a turn table which is 0.1m above ground plane.
Maximum procedure was performed on the highest emissions to ensure EUT compliance.
Span = wide enough to fully capture the emission being measured
RBW = 9kHz
VBW  RBW
Sweep = auto
Detector function = peak
Trace = max hold
For Below 150KHz:
The EUT was placed on a turn table which is 0.1m above ground plane.
Maximum procedure was performed on the highest emissions to ensure EUT compliance.
Span = wide enough to fully capture the emission being measured
RBW = 200Hz
VBW  RBW
Sweep = auto
Detector function = peak
Trace = max hold
Follow the guidelines in ANSI C63.10-2013 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, 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.
Repeat above procedures until all frequency measured was complete.
