| 3 | 3 | HAENNIG, Gerald | A CW RF signal is generated with the Keysight N9310A Signal Generator. This signal is provided to the optical transmitter which converts it into an optical signal which intensity is modulated by RF carrier. The optical recevier converts the optical signal back to an RF CW signal. This signal is measured on the FSV spectrum Analyzer. |

| 5 | 2 | HAENNIG, Gerald | The gain is measured as : Gain = RF POWER [dBm] @ Optical Receiver Out - RF POWER [dBm] @ Optical Transmitter In. |

| 7 | 2 | HAENNIG, Gerald | As they are lossy coaxial cables to connect signal generator to the optical transceiver and optical receiver to spectrum analyzer, this losses have be to taken into account. |
