Report No.: AGC01284230402FE10 Page 47 of 54 12.TRANSMITTER FREQUENCY BEHAVIOR 12.1 PROVISIONS APPLICABLE FCC §90.214 13.2 MEASUREMENT SETUP Report No.: AGC01284230402FE10 Page 48 of 54 12.3 MEASUREMENT METHOD According to TIA/EIA-603 2.2.19 requirement, as for the product different from PTT, we use test steps as follows: 1. Connect DUT into Test discriminator and Storage Oscilloscope and keep DUT stats ON; 2. Input 1kHz signal into DUT; 3. Set the modulation domain analyzer to trigger on the rising edge of the waveform in order to capture a single-shot turn-on of the transmitter signals; 4. Keep DUT in OFF state and Key the PTT; 5. Observe the stored oscilloscope of modulation domain analyzer. The signal trace shall be maintained within the allowable limits during the periods t1 and t2,and shall also remain within limits following t2; 6. Adjust the modulation domain analyzer to trigger on the falling edge of the transmitter waveform in order to capture a single-shot turn-off transmitter of the transmitter signal. 7. Keep the digital portable radio in ON state and unkey the PTT; 8. Observe the stored oscilloscope of modulation domain analyzer, The signal trace shall be maintained within the allowable limits during the period t3. 9. Set the signal generator to the assigned transmitter frequency and modulate it with a 1 kHz tone at ±12.5 kHz deviation and set its output level to -100dBm. 10. Turn on the transmitter. 11. Supply sufficient attenuation via the RF attenuator to provide an input level to the stored oscilloscope 12. that is 40 dB below the maximum allowed input power when the transmitter is operating at its rated power level. Note this power level on the stored oscilloscope as P0. 13. Turn off the transmitter. 14. Adjust the RF level of the signal generator to provide RF power equal to P0. This signal generator RF level shall be maintained throughout the rest of the measurement. 15. Remove the attenuation, so the input power to the stored oscilloscope is increased by 30 dB when the transmitter is turned on. 16. Adjust the vertical amplitude control of the stored oscilloscope to display the 1000 Hz at ±4 divisions vertically centered on the display. Set trigger mode of the Spectrum Analyzer to “Video”, and tune the “trigger level” on suitable level. Then set the “tiger offset” to -10ms for turn on and -15ms for turn off. 17. Turn on the transmitter and the transient wave will be captured on the screen of Spectrum Analyzer. Observe the stored display. The instant when the 1 kHz test signal is completely suppressed is considered to be ton. The trace should be maintained within the allowed divisions during the period t1 and t2. 18. Then turn off the transmitter, and another transient wave will be captured on the screen of Spectrum 19. Analyzer. The trace should be maintained within the allowed divisions during the period t3.
