The UAT Option enables the UAT test capability which can be accessed from the Scenario Screen. UAT test capability allows the user to perform testing on their UAT receiver, including DO-282 MOPS testing. There are several UAT Test Modes of Operation tailored for the different types of DO-282 MOPS tests. For each UAT Test Mode of Operation, there is a common Setup Requirement as well as Common Capabilities. The UAT scenario requires a 1 PPS (One pulse per second) signal input in TX Mod #1 input on the back of the RGS2000NG to run the scenario. • Each channel allows 32 dynamic targets and 1500 static targets. Each target can be defined as an airborne or ground link message. • The user can modify the eye diagram horizontal spacing and also select different filters to change the transition in the eye diagram from positive to negative frequency deviation. • The targets can be defined in reference to an Own aircraft latitude and longitude, or as a specific offset from the Message Start Opportunity (MSO). The RGS-2000NG NextGen TCAS Test Set is designed for the following test applications: • Engineering development, certification, manufacturing and service • TCAS computers • ADS-B In Ground Station Receivers • ADS-R, TIS-B Ground Station Transmitters • Transponders Mode S/ADS-B Out (transponder option)

• Two transmitters or channels are available. UAT RX1 is connected to the top antenna and UAT RX2 is connected to the bottom antenna. • For Overlapping Mode, both internal transmitters are combined to the top antenna port allowing the user to perform the DO-282 MOPS tests associated with reception of overlapping UAT messages. • One UAT transmitter and one pulse modulated transmitter are combined internally to the top antenna port, allowing for the DME fruit DO-282 MOPS test to be run. • The power and frequency of the DME 12 |jS pulse pair can be selected by the user in this mode. • The user can...
