Multi-channel cns co-exciter and control method based on synthetic instrument

Abstract

The invention discloses a multi-channel CNS synergistic exciter based on a synthetic instrument and a control method, wherein the CNS synergistic exciter comprises: a synthetic instrument, including a plurality of excitation sources, each excitation source is connected with an output channel through a radio frequency switch, and the output channel Including two output ports, the RF switch is used to select one of the output ports to output the excitation signal, and the star trigger bus is used to transmit the trigger signal to synchronize multiple excitation sources; the touch screen is used to collect control information and display the excitation signal. Waveform; touch screen for collecting control information and displaying the waveform of the excitation signal. The invention integrates the functions of multiple devices into one device through the PXI bus module, which greatly reduces the hardware volume of the device; in addition, all modules in the PXI chassis are synchronized through the star trigger bus, so that each excitation source can output excitation signals synchronously , to achieve real-time collaborative work of multiple excitation signals, and can be widely used in the field of radio technology.

Description

technical field [0001] The invention relates to the field of radio technology, in particular to a multi-channel CNS co-exciter and method based on a synthetic instrument. Background technique [0002] The current aircraft radio communication navigation and 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 equipment. Although there are also radio system integration experiments, such as integration on a multi-layer chassis, the system hardware is large in size, poor in controllability, low in operating efficiency, and does not meet the needs of signal coordination in real-time. [0003] Name Explanation: [0004] Synthetic Instrumentation: Take advantage of a combination of core hardware and software units used in an open-architecture environment. [0...
