    bandwidth. For 802.11 devices it is suggested to select frequencies in each of the bonded 20 MHz
    channels and the channel center frequency.

    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.
    Note 3: EIRP is based on the highest antenna gain. For MIMO devices refer to KDB Publication
    662911 DQ1.

    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 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.
    Note 3: 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.
