4.5 Corrected Amplitude & Margin Calculation

The Corrected Amplitude is calculated by adding the Antenna Factor and the Cable Factor, and subtracting the
Amplifier Gain from the Amplitude reading. The basic equation is as follows:

                                        Corr. Ampl. = Indicated Reading – Corr. Factor

The “Margin” column of the following data tables indicates the degree of compliance with the applicable limit.
For example, a margin of -6dBμV means the emission is 6dBμV below the maximum limit for Class B. The
equation for margin calculation is as follows:

                               Margin = Corr. Ampl. – FCC Part 15 (RSS-310 Issue 3) Limit

4.6 Environmental Conditions

   Temperature:                 26° C
   Relative Humidity:           52%
   ATM Pressure:                1012 mbar

4.7 Summary of Test Results/Plots

According to the data below, the standards of FCC Part 15.205, 15.209 & 15.227 and RSS-310 Issue 3 &
RSS-Gen Issue 3 of the Industry Canada, and had the worst margin of:

                  -2.54 dBμV at 108.2667 MHz in the Vertical polarization, 9 kHz to 1 GHz, 3Meters

        Note: this EUT was tested in 3 orthogonal positions and the worst case position data was reported.

Note: Testing is carried out with frequency rang 9kHz to the tenth harmonics, which above 5th Harmonics is close
to the noise base even antenna close up to 1meter distance according the measurement of ANSI C63.4.
The measurements greater than 20dB below the limit from 9kHz to 30MHz.

5. Part 15.227(b) - OUT OF BAND EMISSIONS

5.1 Standard Applicable

According to the FCC Part 15.227(b) and RSS-310 Issue 3, the field strength of any emissions which appear
outside of 26.96MHz to 27.28MHz shall not exceed the general radiated emission limits in the FCC Part 15.209
and RSS-310 Issue 3 §3.8.

5.3 Test Procedure

As the radiation test, set the RBW=10kHz VBW=30kHz, observed the outside band of 26.96MHz to 27.28MHz,
than mark the higher-level emission for comparing with the FCC Rules.

5.4 Environmental Conditions

   Temperature:           26° C
   Relative Humidity:     52%
   ATM Pressure:          1022 mbar
