4 Test site
4.1 Description
        The measurements were all performed on a weather protected open area test site (OATS)
        that was modified with a flat sand bed located in the ground plane. The depth of the sand
        bed was more than 0.5 m. The EUT was positioned on the sand bed with no ground plane
        beneath.

        At frequencies below 960 MHz the measurement distance from the antenna to the EUT
        was 3 m. The measurement receiver and related equipment, such as a PC and equipment
        for remote control, were placed next to the test site approximately 10 m from the antenna.

        At frequencies above 960 MHz the measurement distance from the antenna to the EUT
        was 1 m. The measurement receiver and a preamplifier were placed next to the
        measurement antenna while other related equipment was placed next to the site.



4.2 Ambient signals
        A number of ambient signals were frequently detected in the different frequency ranges
        where measurements were made, see table below. Additionally, many signals of short-
        term duration were found. Each measurement signal close to or above the limit was
        examined if ambient or related to the EUT.

5 Results
5.1 Measurement of radiated emission, 30 MHz – 960 MHz
5.1.1 Requirements according to FCC 15.509 (d) and IC RSS-220
         Radiated emission from the EUT in the frequency range 30 MHz to 960 MHz shall not
         exceed the limit as specified below.

            Frequency range              Limit
                30 – 88 MHz             40 dBmV/m
               88 – 216 MHz            43.5 dBmV/m
              216 – 960 MHz             46 dBmV/m



5.1.2 Procedures
         The radiated emission was measured on an Open Area Test Site (OATS) with 3 meters
         measuring distance as described in section 4.1, see Picture 3.

         The EUT was configured and the test was performed in accordance with ANSI C63.4.

         The test was initiated with a pre-scan with peak detector in the frequency range 30 MHz to
         960 MHz. The emission level was measured in 64 different combinations of 16 EUT angle
         positions plus vertical and horizontal polarisation and two antenna heights. For each
         position the EUT was turned manually. The antenna height was changed in two steps at
         1.0 m and 2.5 m.

         The measurement software was used to add antenna factors and cable attenuation and to
         form a composite trace of the peak field strength.

         EUT positions and frequencies with the highest emission were selected based on the pre-
         scan. EUT angle, antenna height and antenna polarisation were thereafter adjusted in order
         to find the highest emission level. The antenna height was changed between 1 m and 4 m.

5.2.2 Procedures
         Radiated emission was measured on an Open Area Test Site (OATS) with 1 m measuring
         distance between the EUT and the measurement antenna, see Picture 4. The antenna
         height was fixed at 1 m and the antenna was slightly tilted and pointed towards the EUT.

         The emission was measured with an RMS detector in the frequency range 960 MHz to
         18 GHz. The number of sweep points for the whole frequency range was 34 080 and the
         total sweep time was 34 s. Thus the dwell time was 1 ms.


                                                                                 Ref No   Page

Picture 4. Measurement setup.

Measurements were performed with the EUT rotated in 16 different positions on the sand
bed and with two antenna polarizations resulting in a total of 32 sweeps.

Measurement software was used to add antenna factors and cable attenuation and the
resulting maximum field strength level were plotted.

After the sweeps field strength levels above the limit were checked manually due to the
high number of ambient signals.

5.3 Measurement of UWB bandwidth, frequency range and peak
emissions
5.3.1 Requirements and definitions according to FCC and IC
5.3.1.1   Definitions according to FCC 15.503 (d) and IC RSS-220
            UWB bandwidth: The frequency band bounded by the points that are 10 dB below the
            highest radiated emission, as based on the complete transmission system including the
            antenna. The upper boundary is designated fH and the lower boundary is designated fL.
            The frequency at which the highest radiated emission occurs is designated fM.

            Center frequency (fC): Equals (fH + fL)/2.

            Fractional bandwidth: Equals 2(fH - fL) / (fH + fL).

            Ultra-wideband (UWB) transmitter/device: An intentional radiator that, at any point in
            time, has a fractional bandwidth equal to or greater than 0.20 or has a UWB bandwidth
            equal to or greater than 500 MHz, regardless of the fractional bandwidth.



5.3.1.2   Requirements according to FCC 15.509 (a) and IC RSS-220 (6.2.1)
            The UWB bandwidth of an imaging system operating under the provisions of this section
            must be below 10.6 GHz.



5.3.1.3   Requirements according to FCC 15.509 (f) and IC RSS-220 (6.2.1)
            For UWB devices where the frequency at which the highest radiated emission occurs, fM
            is above 960 MHz, there is a limit on the peak level of the emissions contained within a
            50 MHz bandwidth centred on fM. The limit is 0 dBm EIRP. It is acceptable to employ a
            different resolution bandwidth and a correspondingly different peak emission limit,
            following the procedures described in FCC 15.521 and in the Annex of IC RS-220.



5.3.2 Requirements according to FCC Waivers
            Combined requirements according to:

             - 1660.5 MHz – 1668.4 MHz
             - 2690 MHz – 2700 MHz



5.3.3 Procedures
         The setup was made so that the EUT antenna was tilted and pointing directly towards the
         measurement antenna. The measuring distance was 3 m.

         To determine the spectrum parameters measurements were performed with peak detector
         with 1 MHz bandwidth with vertical polarisation.

         Measurement software added antenna factors and cable attenuation.

5.3.4 Environmental conditions
          Temperature (inside test facility):    14 to 20 °C



5.3.5 Results
          Results are valid for the described arrangement and operation of the tested EUT.

          The EUT fulfilled the definition of an UWB transmitter according to FCC 15.503 (d) and
          IC RSS-220. The EUT complied with the requirement in IC RSS-220 (6.2.1) and FCC
          15.509 (a, f) with exceptions declared in the FCC waivers.

          The EUT also fulfils the requirements of pulse parameters in the FCC waivers.

          The requirements that the radar device not shall be sold in any hand-held configurations,
          and that the device shall operate with stepped frequency modulation in 2 MHz, 10 MHz or
          20 MHz steps, were confirmed by manufacturer statement but were not verified by
          measurements.



          UWB definition

          Measurement data is presented in diagrams below. From the diagrams data regarding the
          UWB bandwidth was gathered and calculated.

           Frequency of highest emission fM     767 MHz
           Lower boundary fL                    149 MHz
           Upper boundary fH                    1281 MHz
           Centre frequency fC                  715 MHz
           Fractional bandwidth                 1.58


          Emission at fM

          The frequency of highest emission (fM) was 767 MHz, which is below 960 MHz. Thus,
          there is no requirement for the emission at fM measured with peak detector over 50 MHz
          bandwidth.


                                                                                Ref No   Page
