Problems solved by technology
[0002] At present, our company does not have a special tester for the calibration of finished products, which cannot meet the requirements of the radio compass system for pre-installation calibration. It cannot test the various functions and detailed technical indicators of the radio compass system. If it is installed directly, it cannot guarantee the finished product. the quality of
When the system is powered on to check that the system fails, there is no effective means to judge whether it is the fault of the finished product itself or the fault of the on-board circuit or other cross-linking equipment. The fault can only be eliminated on the plane, and the fault phenomenon cannot be reproduced on the ground.

Embodiment Construction
[0012] A radio compass audio power output test device, such as figure 1 shown, including:
[0013] The UHF signal generator 3 is connected with the ADF signal simulator 2 through a radio frequency cable, and sends a radio frequency signal to the ADF signal simulator 2;
[0014] The radio compass audio power output test module 9 is connected to the compass control box 4 and the compass receiver 1 respectively, and forwards the receiving command from the compass control box 4 to the compass receiver 1, and the compass receiver 1 receives the command from the radio frequency. The audio output of the signal demodulation, the audio output is sent to the earphone 5;
[0015] The audio power meter 6 is connected with the radio compass audio power output test module 9 to display the power value of the audio output to the earphone 5;
[0016] The DC stabilized power supply 8 is connected to the static converter control box 7 and the radio compass audio power output test module 9, pro...

The invention belongs to an aircraft avionic system, and provides a radio compass audio power output test device which comprises an ultra-high frequency signal generator 3, a radio compass audio power output test module 9 and an audio power meter 6, wherein the ultra-high frequency signal generator 3 is connected with an ADF signal simulator 2 through a radio frequency cable, and sends a radio frequency signal to the ADF signal simulator 2; the radio compass audio power output test module 9 is connected with a compass control box 4 and a compass receiver 1 separately, forwards a reception instruction from the compass control box 4 to the compass receiver 1, receives the audio output demodulated by the compass receiver 1 from the radio frequency signal according to the reception instruction, and sends the audio output to earphones 5; the audio power meter 6 is connected with the radio compass audio power output test module 9, and displays the power value of the audio output to the earphones 5.
Description
technical field [0001] The invention belongs to an aircraft avionics system, and relates to a radio compass audio power output test device. Background technique [0002] At present, our company has no special tester for the calibration of finished products, which cannot meet the requirements of the radio compass system for pre-installation calibration, and cannot test the functions and detailed technical indicators of the radio compass system. Direct installation cannot guarantee the finished product. the quality of. When the system is powered on to check the failure of the system, there is no effective means to judge whether it is the failure of the finished product itself or the failure of the circuit or other cross-linking equipment on the aircraft. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a radio compass audio power output test device, which can test the audio power output, judge the working state of t...
