【 摘 要 】

This paper is aimed at the single function of detecting and debugging single-board code synchronizer. It is difficult to meet the problem of dynamic reception of various types of arrow televisors. A new type of arrow telemetry solution can be proposed. Tuned single board code synchronizer adjustment method. On the basis of in-depth analysis of YH4 series code synchronizer frequency discrimination and phase discrimination principle, the key links affecting its dynamic performance - code ring reference clock, matched filter output passband voltage, symbol decision level, input signal The detection and debugging methods and working mechanism of the flat and baseline positions are described in detail.
