                                   Appendix A: Frequency Stability


   A.1. Purpose
        This test was performed to determine if the EUT meets the frequency stability requirements of FCC
        Part 74.861, FCC 15.236 and RSS 210 Issue 9, Annex G.
   A.2. Requirements
        FCC part 15.236(f)(3) states:
        “The frequency tolerance of the carrier signal shall be maintained within ±0.005% of the operating
        frequency over a temperature variation of −20 degrees to +50 degrees C at normal supply voltage, and for
        a variation in the primary supply voltage from 85% to 115% of the rated supply voltage at a temperature of
        20 degrees C. Battery operated equipment shall be tested using a new battery.”
        The requirements for RSS 210 Issue 9, Annex G can be found in the table below.




   A.3. Measurement Uncertainty
       All measurements are an estimate of their true value. The measurement uncertainty characterizes,
       with a specified confidence level, the spread of values which may be possible for a given
       measurement system.
        Values of Expanded Measurement Uncertainty (95% Confidence):
                                                    Std uncertainty
                                                       ±u(error)
                 Expanded Uncertainty
                               (U95):                   5.83E-08
        These values can be found in the document titled ‘Frequency Error_Stability – 2018_09_24.xlsx’
        located at \\shure.com\organization\Quality\Product Conformance-Lab Services\Global
        Compliance\Shure EMC Lab\Controlled Documents\Measurement Uncertainties.
             -   Compliance is deemed to occur if no measured disturbance exceeds the disturbance limit;
             -   Non-compliance is deemed to occur if any measured disturbance exceeds the disturbance limit.
   A.4. Test Setup and Instrumentation
        The EUT was heated and cooled in an Espec temperature chamber over a temperature range of
        -30°C to +50°C. The temperature around the EUT was measured and monitored by the built-in
        thermometer. The EUT’s frequency was measured with a spectrum analyzer set to measure signal
        count at 0.1Hz resolution. The center frequency of the spectrum analyzer was set to the selected
        transmit frequency of the EUT (Low, Mid or High). Photographs of the test setup are shown below.
        The test instrumentation can be determined from Table 10-1.

   A.5. EUT Operation
        The device was powered on and transmitting. The three frequencies were set using the buttons on
        the device inside the battery door.
   A.6. Specific Test Procedures
        The temperature chamber was set to -30°C with the EUT inside and powered on.
        The EUT was allowed to soak for ~20 minutes after the temperature chamber reached the set
        temperature.
        The measured frequency of the transmitter was then recorded in the spreadsheet in section D.7.
        The temperature chamber was incremented +10°C with the EUT inside and powered on.
        Steps c. through e. were repeated until the device reached +50°C.
        Steps a. through e. were repeated for representative low, mid and high frequencies within the EUT’s
        operational bands.
   A.7. Results
        The test results can be viewed in the table below.

                                                                                                   6/9/2017


                                                                          Engineering Test Report No. SEL-038B

           With the Low Frequency (LF) audio signal generator set to 500 Hz, the audio input level to the
           DUT shall be adjusted to 8 dB below the limiting threshold (-8 dB (lim)) as declared by the
           manufacturer.
           The corresponding audio output level from the demodulator shall be measured and recorded.
           The input impedance of the noise meter shall be sufficiently high to avoid more than 0,1 dB
           change in input level when the meter is switched between input and output.
           The audio input level shall be increased by 20 dB, i.e. to +12 dB (lim), and the corresponding
           change in output level shall be measured.
           It shall be checked that the audio output level has increased by ≤ 10 dB.
           If this condition is not met, the initial audio input level shall be increased from -8 dB (lim) in 1 dB
           steps until the above condition is fulfilled, and the input level recorded in the test report. This level
           replaces the value derived from the manufacturer's declaration and is defined as -8 dB (lim).
           Measure the input level at the transmitter required to give +12 dB (lim).
           The LF generator shall be replaced with the weighted noise source to Recommendation ITU-R
           BS.559-2 [i.3], band-limited to 15 kHz as described in IEC 60244-13 [2], and the level shall be
           adjusted such that the measured input to the transmitter corresponds to +12 dB (lim).
           If the transmitter incorporates any ancillary coding or signalling channels (e.g. pilot-tones), these
           shall be enabled prior to any spectral measurements.
           If the transmitter incorporates more than one audio input, e.g. stereo systems, the second and
           subsequent channels shall be simultaneously driven from the same noise source, attenuated to a
           level of -6 dB (lim).
           The transmitter RF output spectrum shall be measured, using a spectrum analyser with the
           following settings:
                    ▪   centre frequency: fc: Transmitter (Tx) nominal frequency;
                    ▪   dispersion (Span): fc - 1 MHz to fc + 1 MHz;
                    ▪   Resolution BandWidth (RBW): 1 kHz;
                    ▪   Video BandWidth (VBW): 1 kHz;
                    ▪   detector: Peak hold.


           Figure 8 shows the spectrum mask for all analogue systems in the band. The -90 dBc point shall
           be ±1 MHz from fc measured with an average detector. To comply, a measured value shall fall
           below the mask limit.”
        A +12dB level of -28dBV and a -8dB level of -48dBV were chosen using the first set of instructions,
        and the output RF power was measured with inputs of -28dBV for the +12dB level and -46dBV for the
        -6dB level.
   B.7. Results
        The necessary bandwidth data are presented on the following pages. Data are shown as the
        maximum relative level of the output level within the emission mask.

   C.3. Measurement Uncertainty
        All measurements are an estimate of their true value. The measurement uncertainty characterizes,
        with a specified confidence level, the spread of values which may be possible for a given
        measurement system.

             Since ULAB is less than or equal to UFCC:
             - Compliance is deemed to occur if no measured disturbance exceeds the disturbance limit;
             - Non-compliance is deemed to occur if any measured disturbance exceeds the disturbance
                limit.

   C.5. EUT Operation
        The device was powered up and the frequency was set using the buttons on the device, with the
        audio gain set to 0. Testing was conducted with the EUT set to the three frequencies chosen within
        the operating frequency range of H11: 572.125MHz, 584.125MHz, and 595.850MHz and J11:
        596.125MHz, 606.125MHz, and 615.875MHz. The device was powered by two AA batteries.
   C.6. Specific Test Procedures
        All tests were performed in a 28ft. x 20ft. x 18.5ft. 3m semi-anechoic test chamber. The walls and
        ceiling of the shielded chamber are lined with ferrite tiles. Anechoic absorber material is installed over
        the ferrite tile. The floor of the chamber is used as the ground plane. The chamber complies with
        ANSI C63.4-2003 for site attenuation.

        The shielded enclosure prevents emissions from other sources, such as radio and TV stations from
        interfering with the measurements. All power lines and signal lines entering the enclosure pass
        through filters on the enclosure wall. The power line filters prevent extraneous signals from entering
        the enclosure on these leads.




                             BLOCK DIAGRAM OF SHIELDED ENCLOSURE

        Preliminary radiated measurements were performed to determine the frequencies where the
        significant emissions might be found. The broadband measuring antenna was positioned at a 3 meter
        distance from the EUT. The frequency range from 25MHz to 1GHz was investigated using a peak
        detector function with the BiConiLog antenna at horizontal and vertical polarization, and with several
        different orientations of the EUT with respect to the antenna. The maximum levels measured for each
        antenna polarization were then automatically plotted. The resultant field strength (FS) is a summation
        in decibels (dB) of the EMI receiver measurement (ERM), the antenna correction factor (AF), and the
        cable loss factor (CF). If an external pre-amplifier is used, the total is reduced by its gain (-PA).

        Formula 1: FS (dBµV/m) = MTR (dBµV) + AF (dB/m) + CF (dB) + (- PA (dB))

        To convert the Field Strength dBµV/m term to µV/m, the dBµV/m is first divided by 20. The Base 10
        AntiLog is taken of this quotient. The result is the Field Strength value in µV/m terms.

        Formula 2: FS (µV/m) = AntiLog [(FS (dBµV/m))/20]

        Final radiated RF emissions were performed on all significant broadband and narrowband emissions
        found in the preliminary sweeps using the following methods:

                                                                                                       6/9/2017

             1) Measurements of all significant broadband and narrowband signals from 25MHz to 1GHz
        were made using a quasi-peak detector and a BiConiLog antenna. Measurements above 1GHz were
        made using an average detector and a broadband double ridged waveguide antenna.
             2) To ensure that maximum or worst case, emission levels were measured, the following steps
        were taken:
              i.     The EUT was rotated so that all of its sides were exposed to the receiving antenna.
             ii.     Since the measuring antenna is linearly polarized, both horizontal and vertical field
                     components were measured.

        The measuring antenna was raised and lowered from 1 to 4 meters for each antenna polarization to
        maximize the readings.

                                    Appendix D: RF Output Power


   D.1. Purpose
        This test was performed to determine if the EUT meets the RF power output requirements of FCC
        15.236 and RSS 210.9.
   D.2. Requirements
        As stated in FCC 15.236(d)(1), The maximum radiated power shall not exceed the following values:
        In the bands allocated and assigned for broadcast television and in the 600 MHz service band: 50 mW
        EIRP
        As stated in RSS 210.9 Annex G, transmitter EIRP shall be limited to the values listed in Table G1
        below, or 250 mW.




   D.3. Measurement Uncertainty
       All measurements are an estimate of their true value. The measurement uncertainty characterizes,
       with a specified confidence level, the spread of values which may be possible for a given
       measurement system.
        Values of Expanded Measurement Uncertainty (95% Confidence):
                                                          Std uncertainty
                                                          +u(dB)              -u(dB)
                           Expanded
                        Uncertainty (U95):
                                                          0.461               0.461

   D.5. EUT Operation
          The EUT was powered up and the transmit frequencies (H11: 572.125MHz, 584.125MHz, and
          595.850MHz, J11: 596.125MHz, 606.125MHz, and 615.875MHz) were selected using the front panel
          controls.
   D.6. Specific Test Procedures
           a.   The EUT’s RF output was connected to an artificial antenna at ambient temperature.
           b.   The EUT’s frequency was set at the first test frequency.
           c.   The power level was measured and recorded.
           d.   The antenna gain was added to the measured power in order to calculate the E.I.R.P.,
                acknowledging that the RF output was connected directly to the artificial antenna, bypassing
                any cables. The equation below was used to calculate the EIRP values.




           e. Steps b and c were repeated at the other test frequencies.
   D.7. Results
          The results of the power output test can be seen below.
