4. Transmitted Signal Information Frequency Various documents referenced in Section 2 of this exhibit provide guidance as to how to perform Low Level Coupling (LLC) testing. This guidance specifies the use of a signal generator and receiver system setup in a tracking generator configuration such that the test frequency is swept continuously across a specified frequency band. Testing using swept frequencies rather than widely spaced discrete frequencies allows for a more accurate measurement of aircraft and wiring resonant responses. This method also simplifies the test setup and minimizes frequency dwell time. The effective dwell time at each swept frequency is much less than 1s. We request permission to perform swept frequency testing across all approved test frequency bands listed in the application. Frequencies reserved for emergency services or local aircraft control will be omitted from the test. Modulation All testing is performed using a Continuous Wave (CW) signal (i.e. no modulation). Therefore, no actual data is being transmitted during the test. Power Transmitted power must be high enough to allow accurate monitoring using a sensitive receiver system. All transmitted power levels will remain less than the specified band specific Effective Radiated Power (ERP) as specified in the application. The power levels requested are for maximum Effective Isotropic Radiated Power (EIRP) at the transmit antenna. Coordination with the local FCC and FAA can be accomplished as necessary. 5. “Stop Buzzer” Contacts The following contacts can be contacted at any time to stop the test in case of a conflict.
