EUT Pseudorandom Frequency Hopping Sequence
The pseudorandom sequence may be generated in a nine-stage shift register whose
5th and 9th stage outputs are added in a modulo-two addition stage. And the result is
fed back to the input of the first stage. The sequence begins with the first one of 9
consecutive ones; i.e. the shift register is initialized with nine ones.
• Number of shift register stages: 9
• Length of pseudo-random sequence: 29 -1 = 511 bits
• Longest sequence of zeros: 8 (non-inverted signal)
An example of Pseudorandom Frequency Hopping Sequence as follow:
Each frequency used equally on the average by each transmitter.
The system receivers have input bandwidths that match the hopping channel
bandwidths of their corresponding transmitters and shift frequencies in
synchronization with the transmitted signals.

Above 1GHz
Test Mode: Transmitting mode with modulation
Test Procedure:
1. The testing follows the guidelines in Spurious
Radiated Emissions of ANSI C63.10:2013
Measurement Guidelines.
2. For the radiated emission test below 1GHz:
The EUT was placed on a turntable with 0.8 meter
above ground. The EUT was set 3 meters from the
interference receiving antenna, which was mounted
on the top of a variable height antenna tower. The
EUT was arranged to its worst case and then tune
the antenna tower (from 1 m to 4 m) and turntable
(from 0 degree to 360 degrees) to find the maximum
reading. A pre-amp and a high PASS filter are used
for the test in order to get better signal level.
For the radiated emission test above 1GHz:
Place the measurement antenna on a turntable with
1.5 meter above ground, which is away from each
area of the EUT determined to be a source of
emissions at the specified measurement distance,
while keeping the measurement antenna aimed at
the source of emissions at each frequency of
significant emissions, with polarization oriented for
maximum response. The measurement antenna
may have to be higher or lower than the EUT,

depending on the radiation pattern of the emission
and staying aimed at the emission source for
receiving the maximum signal. The final
measurement antenna elevation shall be that which
maximizes the emissions. The measurement
antenna elevation for maximum emissions shall be
restricted to a range of heights of from 1 m to 4 m
above the ground or reference ground plane.
3. Set to the maximum power setting and enable the
EUT transmit continuously.
4. Use the following spectrum analyzer settings:
(1) Span shall wide enough to fully capture the
emission being measured;
(2) Set RBW=100 kHz for f < 1 GHz, RBW=1MHz
for f>1GHz ; VBWRBW;
Sweep = auto; Detector function = peak; Trace
= max hold for peak
(3) For average measurement: use duty cycle
correction factor method per
15.35(c). Duty cycle = On time/100 milliseconds
On time =N1*L1+N2*L2+...+Nn-1*LNn-1+Nn*Ln
Where N1 is number of type 1 pulses, L1 is
length of type 1 pulses, etc.
Average Emission Level = Peak Emission
Level + 20*log(Duty cycle)
Corrected Reading: Antenna Factor + Cable
Loss + Read Level - Preamp Factor = Level
Test results: PASS

Note:
1. Worst case Duty cycle = on time/100 milliseconds = (2.908*26+1.842)/100= 0.7745
2. Worst case Duty cycle correction factor = 20*log (Duty cycle) = -2.22dB
3. 2DH5 has the highest duty cycle worst case and is reported.
4. The average levels were calculated from the peak level corrected with duty cycle correction factor (-2.22dB)
derived from 20log (dwell time/100ms). This correction is only for signals that hop with the fundamental signal,
such as band-edge and harmonic. Other spurious signals that are independent of the hopping signal would not
use this correction.
