  1.    The emissions were measured for the worst case as follows:
        (a): within a band of frequencies defined by the carrier frequency plus and minus
             one channel.

             harmonic of the carrier frequency, or 40GHz, whichever is lower.

        the permissible value need not be specified.

  SPECIFICATION:            47 CFR 2.1053 (a)
  GUIDE:                    ANSI/TIA/EIA‐603, Paragraph 1.2.12


                                MEASUREMENT PROCEDURE

  1.2.12.1 Definition: Radiated spurious emissions are emissions from the equipment when
           transmitting load on a frequency or frequencies which are outside an occupied band
           sufficient to ensure transmission of information of required quality for the class of
           communications desired.

  1.2.12.2 Method of measurement

  A)      Connect the equipment as illustrated.

  B)      Adjust the spectrum analyzer for the following settings:
          1) Resolution Bandwidth <= 3kHz
          2) Video Bandwidth >= 10kHz
          3) Sweep Speed <= 2000Hz/second
          4) Detector Mode = Positive Peak

  C)      Place the transmitter to be tested on the turntable in the standard test site.
          The transmitter is transmitting into a non‐radiating load which is placed on the
          turntable. The RF cable to this load should be of minimum length.

                              STANDARD TEST SITE

  D)      For each spurious measurment the test antenna should be adjusted to the correct
          length for the frequency involved. This length maybe determined from a calibration
          ruler supplied with the equipment. Measurements shall be made from the lowest
          radio frequency generated in the equipment to the tenth harmonic of the carrier,
          except for the region close to the carrier qeual to ± the test bandwidth
          (see section 1.3.4.4).

  E)      For each spurious frequency, raise and lower the test antenna from 1 m to 4 m to
          obtain a maximum reading on the spectrum analyzer with the test antenna at
          horizontal polarity.

  G)     Reconnect the equipment as illustrated.

  H)     Keep the spectrum analyzer adjusted as in step B).

  I)     Remove the transmitter and replace it with a substitution antenna (the antenna
         should be half‐wavelength for each frequency involved).
         The center of the substitutuion antenna should be approximately at the same location
         as the center of the transmitter. At lower frequencies, where the substitution antenna
         is very long, this will be impossible to achieve when the antenna is plarized vertically.
         In such case the lower end of the antenna should be 0.3m above the ground.

  J)     Feed the substitution antenna at the transmitter end with a signal generator connected
         to the antenna by means of a non‐radiating cable. With the antennas at both ends
         horizontally polarized and with the signal generator tuned to a particular spurious
         frequency, raise and lower the test antenna to obtain a maximum reading at the
         spectrum analyzer. Adjust the level of the signal generator output untill the
         previusl recorded maximum reading for the set of conditions is obtained. This should
         be done carefully repeating the adjustment of the test antenna and generator output.

  K)     Repeat step J) with both antennas vertically polarized for each spurious frequency.

  L)     Calculate power in dBm into a reference ideal half‐wave dipole antenna by reducing
         the readings obtained in step J) and K) by the power loss in the cable between the
         generator and the antenna and futher corrected for the gain of the substitution
         antenna used relative to an ideal half‐wave dipole antenna.

  M)     The levels recorded in step L) are absolute levels of radiated spurious emissions
         in dBm. The radiated spurious emissions in dB can be calculated by the following:

  Radiated spurious emissions dB = 10log(TX power in watts/0.001) ‐ the levels in step L)

  SPECIFICATION:          47 CFR 2.1049 (c) (1)
  GUIDE:                  ANSI/TIA/EIA‐603, Paragraph 2.2.11
  TEST EQUIPMENT:         As per previous page

                             MEASUREMENT PROCEDURE

  1.    The EUT and test equipment ware set up as shown on the following page, with
        the spectrum analyzer connected.

  2.    For EUTʹs supporting audio modulation, the audio signal generator was adjusted
        to the frequency of maxmum response and with output level set for ±2.5kHz
        deviation (or 50% modulation). With level constant, the signal level was increased
        16dB.

  3.    For EUTʹs supporting digital modulation, the digital modulation mode was operated
        to its maximum extent.

  4.    The occupied bandwidth was measured with the spectrum analyzer controls set as
        shown on the test results.

  5.    MEASUREMENT RESULTS: ATTACHED

  2.    The modulation response was measured for each of three frequencies (one of
        which was the frequency of maximum response), and the input voltage was
        varied and was observed on an Agilent 8901B modulation analyzer.

  3.    The input level was varied from 30% modulation (± 1.5kHz deviation) to at least
        20dB higher than the saturation point.

  1.                      The EUT was placed in a temperature chamber at 25±5℃ and connected as for
                          ʺFrequency Stability ‐ Temperature Variationʺ test.

  2.                      The power supply voltage to the EUT was varied from 85% to 115% of the nominal
                          value measured at the input to the EUT.

  3.                      The variation in frequency was measured for the worst case.
