2.3 DFS MEASUREMENT INSTRUMENTATION
a. RADAR GENERATION SYSTEM
An Agilent PSG is used as the radar-generating source. The integral arbitrary waveform generators are
programmed using Agilent’s “Pulse Building” software and Elliott custom software to produce the
required waveforms, with the capability to produce both unmodulated and modulated (FM Chirp) pulses.
Where there are multiple values for a specific radar parameter then the software selects a value at
random and, for FCC tests,the software verifies that the resulting waveform is truly unique.
With the exception of the hopping waveforms required by the FCC’s rules (see below),the radar
generator is set to a single frequency within the radar detection bandwidth of the EUT.
Frequency hopping radar waveforms are simulated using a time domain model. A randomly hopping
sequence algorithm (which uses each channel in the hopping radar’s range once in a hopping
sequence) generates a hop sequence. A segment of the first 100 elements of the hop sequence are
then examined to determine if it contains one or more frequencies within the radar detection bandwidth
of the EUT. If it does not then the first element of the segment is discarded and the next frequency in the
sequence is added. The process repeats until a valid segment is produced. The radar system is then
programmed to produce bursts at time slots coincident with the frequencies within the segment that fall
in the detection bandwidth. The frequency of the generator is stepped in 1 MHz increments across the
EUT’s detection range.
The radar signal level is verified during testing using a CW signal with the AGC function switched on.
Correction factors to account for the fact that pulses are generated with the AGC functions switched off
are measured annually and an offset is used to account for this in the software.The generator output is
connected to the coupling port of the conducted set-up or to the radar-generating antenna.
b. CHANNEL MONITORING SYSTEM
Channel monitoring is achieved using a spectrum analyzer and digital storage
oscilloscope. The analyzer is configured in a zero-span mode, center frequency set to the
radar waveform’s frequency or the center frequency of the EUT’s operating channel.
The IF output of the analyzer is connected to one input of the oscilloscope and analyzer.
A signal generator output is set to send either the modulating signal directly or a pulse gate with an
output pulse co-incident with each radar pulse. This output is connected to a second input on the
oscilloscope and the oscilloscope displays both the channel traffic (via the if input) and the radar pulses
on its display.
For in service monitoring tests the analyzer sweep time is set to > 20 seconds and the
oscilloscope is configured with a data record length of 10 seconds for the short duration
and frequency hopping waveforms, 20 seconds for the long duration waveforms. Both
instruments are set for a single acquisition sequence. The analyzer is triggered 500ms
before the start of the waveform and the oscilloscope is triggered directly by the
modulating pulse train. Timing measurements for aggregate channel transmission time
and channel move time are made from the oscilloscope data, with the end of the
waveform clearly identified by the pulse train on one trace. The analyzer trace data is
used to confirm that the last transmission occurred within the 10-second record of the
Page 11 of 22
Report No.: STS1805169W05
oscilloscope. If necessary the record length of the oscilloscope is expanded to capture
the last transmission on the channel prior to the channel move.
Channel availability check time timing plots are made using the analyzer. The analyzer is triggered at
start of the EUT’s channel availability check and used to verify that the EUT does not transmit when
radar is applied during the check time.
The analyzer detector and oscilloscope sampling mode is set to peak detect for all plots.

3.2.2 DFS MEASUREMENT METHODS
a. DFS – CHANNEL CLOSING TRANSMISSION TIME AND CHANNEL MOVE TIME
Channel Move Time and the Channel Closing Transmission Time should be performed with Radar
Type 0. The measurement timing begins at the end of the Radar Type 0 burst.
The Channel Closing Transmission Time is comprised of 200 milliseconds starting at the
beginning of the Channel Move Time plus any additional intermittent control signals required to
facilitate a Channel move (an aggregate of 60 milliseconds) during the remainder of the 10 second
period. The aggregate duration of control signals will not count quiet periods in between
transmissions.
b.DFS – CHANNEL NON-OCCUPANCY AND VERIFICATION OF PASSIVE SCANNING
Non-occupancy Period. A channel that has been flagged as containing a radar system, either by a
channel availability check or in-service monitoring, is subject to a non-occupancy period of at least
30 minutes. The non-occupancy period starts at the time when the radar system is detected.
Page 17 of 22
Report No.: STS1805169W05
c. CHANNEL AVAILABILITY CHECK TIME
Channel Availability Check Time. A U-NII device shall check if there is a radar system already
operating on the channel before it can initiate a transmission on a channel and when it has to
move to a new channel. The U-NII device may start using the channel if no radar signal with a
power level greater than the interference threshold values listed in paragraph (h)(2) of this section,
is detected within 60 seconds.
d. CONTROL (TPC)
Compliance with the transmit power control requirements for devices is demonstrated through
measurements showing multiple power levels and manufacturer statements explaining how the
power control is implemented.
e. DETECTION PROBABILITY / SUCCESS RATE
During the U-NII Detection Bandwidth detection test, radar type 0 should be used. For each
frequency step the minimum percentage of detection is 90 percent. Measurements are performed
with no data traffic. Minimum 100% of the U-NII 99% transmission power bandwidth.
f. NON- OCCUPANCY PERIOD
During the 30 minutes observation time, UUT did not make any transmissions on a channel after a
radar signal was detected on that channel by either the Channel Availability Check or the
In-Service Monitoring
3.2.3 DFS CONDUCTION TEST METHOD
a. The signal level of the simulated waveform is set to a reference level equal to the
threshold level (plus 1dB if testing against FCC requirements). Lower levels may also be
applied on request of the manufacturer.
The signal level is verified by measuring the CW signal level at the coupling point to the
RDD antenna port. The radar signal level is calculated from the measured level, R (dBm)
and the lowest gain antenna assembly intended for use with the RDD
If both master and client devices have radar detection capability then the radar level at
the non RDD is verified to be at least 20dB below the threshold level to ensure that any
responses are due to the RDD detecting radar.
The antenna connected to the channel monitoring subsystem is positioned to allow both
master and client transmissions to be observed, with the level of the EUT’s transmissions
between 6 and 10dB higher than those from the other device.
b.Set-upB is a set-up whereby the UUT is an RLAN device operating in slave mode, with or
without RadarInterference Detection function. This set-up also contains an RLAN device operating
in master mode. The radar test signals are injected into the master device. The UUT (slave
device)is associated with the master device.Figure 5 shows an example for Set-up B. The set-up
usedshall be documented in the test report.
