Multi-channel CNS cooperative exciter based on synthesis instrument and control method

Abstract

The invention discloses a multi-channel CNS cooperative exciter based on a synthesis instrument and a control method, and the CNS cooperative exciter comprises the synthesis instrument which comprisesa plurality of excitation sources, each excitation source is connected with an output channel through a radio frequency switch, the output channel comprises two output ports. The radio frequency switch is used for selecting one output port to output an excitation signal and transmitting a trigger signal for synchronizing a plurality of excitation sources by adopting a star-shaped trigger bus; thetouch screen is used for collecting control information and displaying the waveform of the excitation signal; and the touch screen is used for collecting control information and displaying the waveform of the excitation signal. According to the invention, the functions of multiple devices are integrated into one device through the PXI bus module, so that the hardware size of the device is greatlyreduced; besides, all modules in the PXI case are synchronized through the star-shaped trigger bus, so that the excitation sources synchronously output excitation signals, real-time cooperative workof multiple excitation signals is achieved, and the method can be widely applied to the technical field of radio.

Description

technical field [0001] The invention relates to the field of radio technology, in particular to a multi-channel CNS synergistic exciter and method based on a synthesis instrument. Background technique [0002] The current aircraft radio communication navigation monitoring system integration test and simulation debugging need to use many GPIB bus instruments to work at the same time, such as radio integrated tester, altimeter simulator, compass simulator, ATC test equipment, DME test equipment, ADS-B Test equipment and other special instruments. Although there are also radio system integration tests, such as integration on a multi-layer chassis, the system hardware is large in size, poor in controllability, low in operating efficiency, and the real-time performance does not meet the signal coordination requirements. [0003] Name explanation: [0004] Synthetic Instrumentation: Leverages a combination of core hardware and software elements used in an open architecture envir...
