For non-adjustable fixed channel receiver systems, receiver sensitivity of products will be lower because of differences in coil and capacitor parameters, so assembly must be tested after welding and installing. Based on the antenna resonant principle and actual parameters test principle, measurement analysis system is designed. Frequency conversion output is achieved by using DDS and single-chip, a wide range of scanning is achieved by tracking the amplitude and accurate resonance is achieved by tracking the phase difference. Besides, Light control relay is used to switch different circuit to meet the requirements of multi-loop testing at a high-resolution at the same time. The system developed for analyzing and testing LC receiver antenna parameters can meet the real-time requirements of production line.
