                                 If EUT consist of multiple antenna assembly (multiple antenna are used in EUT
                                 regardless of spatial multiplexing MIMO configuration), the radiated test should
                                 be performed with highest antenna gain of each antenna type.
Operating Mode > 1GHz CTX
Note: The EUT can only be used at Y axis position.

Note 1: Test distance for frequencies at or above 30 MHz, measurements may be performed at a distance
        other than the limit distance provided they are not performed in the near field and the emissions to
        be measured can be detected by the measurement equipment. When performing measurements at
        a distance other than that specified, the results shall be extrapolated to the specified distance using
        an extrapolation factor of 20 dB/decade (inverse of linear distance for field-strength measurements,
        inverse of linear distance-squared for power-density measurements).
Note 2: Test distance for frequencies at below 30 MHz, measurements may be performed at a distance
        closer than the EUT limit distance; however, an attempt should be made to avoid making
        measurements in the near field. When performing measurements below 30 MHz at a closer distance
        than the limit distance, the results shall be extrapolated to the specified distance by either making
        measurements at a minimum of two or more distances on at least one radial to determine the proper
        extrapolation factor or by using the square of an inverse linear distance extrapolation factor (40
        dB/decade). The test report shall specify the extrapolation method used to determine compliance of
        the EUT.
Note 3: Using the distance of 1m during the test for above 18 GHz, and the test value to correct for the
        distance factor at 3m.

3.1.3     Test Procedures
                                                Test Method
    The average emission levels shall be measured in [duty cycle ≥ 98 or duty factor].
    Refer as ANSI C63.10, clause 6.10.3 band-edge testing shall be performed at the lowest frequency
     channel and highest frequency channel within the allowed operating band.
    For the transmitter unwanted emissions shall be measured using following options below:
          Refer as FCC KDB 558074, clause 8.6 for unwanted emissions into restricted bands.
                Refer as FCC KDB 558074, clause 8.6 & C63.10 clause 11.12.2.5.1(trace averaging for duty
                cycle ≥98%).
                Refer as FCC KDB 558074, clause 8.6 & C63.10 clause 11.12.2.5.2(trace averaging + duty
                factor).
                Refer as FCC KDB 558074, clause 8.6 & C63.10 clause 11.12.2.5.3(Reduced VBW≥1/T).
                Refer as ANSI C63.10, clause 11.12.2.5.3 (Reduced VBW). VBW ≥ 1/T, where T is pulse time.
                Refer as ANSI C63.10, clause 7.5 average value of pulsed emissions.
                Refer as FCC KDB 558074, clause 8.6 & C63.10 clause 11.12.2.4 measurement procedure
                peak limit.
    For the transmitter band-edge emissions shall be measured using following options below:
          Refer as FCC KDB 558074 clause 8.7 & C63.10 clause 11.13.1, When the performing peak or
           average radiated measurements, emissions within 2 MHz of the authorized band edge may be
           measured using the marker-delta method described below.
          Refer as FCC KDB 558074, clause 8.7 (ANSI C63.10, clause 6.10.6) for marker-delta method for
           band-edge measurements.
          Refer as FCC KDB 558074, clause 8.7 for narrower resolution bandwidth (100kHz) using the band
           power and summing the spectral levels (i.e., 1 MHz).
          For conducted unwanted emissions into restricted bands (absolute emission limits).
           Devices with multiple transmit chains using options given below:
           (1) Measure and sum the spectra across the outputs or
           (2) Measure and add 10 log(N) dB
          For FCC KDB 662911 The methodology described here may overestimate array gain, thereby
           resulting in apparent failures to satisfy the out-of-band limits even if the device is actually
           compliant. In such cases, compliance may be demonstrated by performing radiated tests around
           the frequencies at which the apparent failures occurred.
