                                                  remaining 10 second periods. (Notes 1 and 2).
            U-NII Detection Bandwidth             Minimum 100% of the 99% power bandwidth (Note 3).
Note 1: 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.
Note 2: 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
        Channel changes (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.
Note 3: During the U-NII Detection Bandwidth detection test, radar type 0 is used and for each frequency
        step the minimum percentage of detection is 90%. Measurements are performed with no data traffic.

Note 1: This is the level at the input of the receiver assuming a 0 dBi receive antenna.
Note 2: Throughout these test procedures an additional 1 dB has been added to the amplitude of the test
        transmission waveforms to account for variations in measurement equipment. This will ensure that
        the test signal is at or above the detection threshold level to trigger a DFS response.
Note3: EIRP is based on the highest antenna gain. For MIMO devices refer to KDB Publication 662911D01.

   There are a total of 8 to 20 Bursts in the 12 second period, with the number of Bursts being randomly chosen.
    This number is Burst Count.
   Each Burst consists of 1 to 3 pulses, with the number of pulses being randomly chosen. Each Burst within
    the 12 second sequence may have a different number of pulses.
   The pulse width is between 50 and 100 microseconds, with the pulse width being randomly chosen. Each
    pulse within a Burst will have the same pulse width. Pulses in different Bursts may have different pulse
    widths.
   Each pulse has a linear FM chirp between 5 and 20 MHz, with the chirp width being randomly chosen. Each

        example, with a radar frequency of 5300 MHz and a 20 MHz chirped signal, the chirp starts at 5290 MHz and
        ends at 5310 MHz.
       If more than one pulse is present in a Burst, the time between the pulses will be between 1000 and 2000
        microseconds, with the time being randomly chosen. If three pulses are present in a Burst, the time between
        the first and second pulses is chosen independently of the time between the second and third pulses.
       The 12 second transmission period is divided into even intervals. The number of intervals is equal to Burst
        Count. Each interval is of length (12,000,000 / Burst Count) microseconds. Each interval contains one Burst.
        The start time for the Burst, relative to the beginning of the interval, is between 1 and [(12,000,000 / Burst
        Count) – (Total Burst Length) + (One Random PRI Interval)] microseconds, with the start time being

        chosen independently.

The FCC Type 6 waveform uses a static waveform with 100 bursts in the instruments ARB. In addition, the RF list
mode is operated with a list containing 100 frequencies from a randomly generated list and it had be ensured that
at least one of the random frequencies falls into the UNII Detection Bandwidth of the DUT. Each burst from the
waveform file initiates a trigger pulse at the beginning that switches the RF list from one item to the next one.

3.3       Dynamic In-Service Monitoring Test (Zero-Wait CAC)
3.3.1     Measuring Instruments
Refer a test equipment and calibration data table in this test report.

3.3.2     Test Procedure
 Pre-clearing a DFS channel for zero time switching from a non-DFS channel
 Before the operation channel moves from non-DFS channels to DFS channels for zero time switching,
 one minute CAC should be performed on the targeted switching channel to make sure no radar presence.
 When CAC completed with no radar presence, channel move to targeted channel immediately. If radar
 detected at any time during CAC, EUT stays on the original non-DFS channel.
