7.3.   Limits

       The provisions of Section 15.205 of this part apply to intentional radiators operating under this
       section.
       Radiated emissions which fall in the restricted bands, as defined in Section 15.205, must also
       comply with the radiated emission limits specified in Section 15.209:
                           FCC Part 15 Subpart C Paragraph 15.209 Limits

       Remarks :    1. RF Voltage (dBuV) = 20 log RF Voltage (uV)
                    2. In the Above Table, the tighter limit applies at the band edges.
                    3. Distance refers to the distance in meters between the measuring instrument
                    antenna and the closed point of any part of the device or system.

7.4.   Test Procedure

       The EUT and its simulators are placed on a turn table which is 0.8 meter above ground. The
       turn table can rotate 360 degrees to determine the position of the maximum emission level.
       The EUT was positioned such that the distance from antenna to the EUT was 3 meters.
       The antenna can move up and down between 1 meter and 4 meters to find out the maximum
       emission level.
       Both horizontal and vertical polarization of the antenna are set on measurement. In order to
       find the maximum emission, all of the interface cables must be manipulated according to
       ANSI C63.4:2009 on radiated measurement.
       The bandwidth below 1GHz setting on the field strength meter is 120 kHz, above 1GHz are 1 MHz.
       The EUT was setup to ANSI C63.4, 2009; tested to DTS test procedure of FCC KDB-789033
       for compliance to FCC 47CFR Subpart E requirements.

7.5.   Uncertainty

       ± 3.8 dB below 1GHz
       ± 3.9 dB above 1GHz
