All measurements made by Richard Read, Senior Design Engineer. 2.1046: RF power output The output power to the antenna was measured as 21.3dBm, (135mW), using a spectrum analyser. (This figure does not include cable loss, which is estimated as 0.5dB.) Test report no. 97/7096/4 page 8 gives the carrier power as 140mW. 2.1047: Modulation characteristics The microphone was disconnected and the audio pre-amp was fed with the output of an audio sweep generator. (It was not possible to view the response directly, as the DSO has no X-input!). Readings were taken at spot frequencies. Frequency kHz Output V pk-pk Relative gain dB 11.50 21.04-3.2 30.68-6.9 40.34-12.9 50.13-21.2 -25 -20 -15 -10 -5 0 12345 Frequency (KHz) Amplitude relative to 1KHz, dB 2.1049: Occupied bandwidth The FCC definition of occupied bandwidth is’ the frequency bandwidth such that below its lower and above its upper frequency limits, the mean powers radiated are each equal to 0.5 per cent of the total mean power radiated’. This corresponds to the 23dB bandwidth, (10log0.005). Modulation was applied with a swept signal ramping from 1KHz to 5KHz. The figure above shows that the occupied bandwidth for the 121.5MHz transmission is 8.5kHz. 2.1051: Spurious emissions at antenna terminals The R3 VHF radio is not designed to operate without an antenna; the antenna is an integral part of the unit. However, measurements of the spectrum at the transmitter output are shown below. The limit of 1.5GHz is the limitation of the available test equipment. 2.1053: Field strength of spurious radiation Refer to performance test report no. 97/7096/4 page 18. 2.1055: Frequency stability Measurements were carried out in 10C steps between -20C and +50C as required under part 80 of the rules. All measurements made with the frequency counter referenced to a Rubidium frequency standard.
