The specification used was with the limits of Part 15.205 & 15.109 of the FCC Rules. According to ANSI Standard C63.4-2009 § 12.1.1.1 (SUPERREGENERATIVE RECEIVER): A Signal Generator was set to the unit under test operating frequency. An unmodulated continuous wave (CW) signal was radiated at the superregenerative receiver operating frequency to cohere the characteristic broadband emissions from the receiver. The external I/O cables were draped along the test table and formed a bundle 30 to 40 cm long in the middle. The spacing between the peripherals was 10 cm.

Scientific Toys Ltd. Model: 21876 3.4 Test Receiver Setup During the radiated emission test, the test receiver was set with the following configurations: Start Frequency .......................................................................... 30 MHz Stop Frequency........................................................................... 1000 MHz Sweep Speed .............................................................................. Auto IF Bandwidth.............................................................................. 100 kHz Quasi-Peak Adapter Bandwidth ................................................. 120 kHz Quasi-Peak Adapter Mode ......................................................... Normal 3.5 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 Part 15.109 of the FCC Rules. The equation for margin calculation is as follows: Margin = Corr. Ampl. – Limit of Part 15.109 (RSS-310 Issue 3) 3.6 Environmental Conditions Temperature: 25 °C Relative Humidity: 54% ATM Pressure: 1011 mbar 3.7 Summary of Test Results/Plots According to the data, the EUT is complied with the standards under Part 15.109 of the FCC Rules, and had the worst margin of: -4.00 dBμV at 833.3171 MHz in the Vertical polarization, 30 MHz to 1 GHz, 3 Meters REPORT NO.: GKK201204120B PAGE 8 OF 10 PART 15.109 & RSS-310 ISSUE 3
