摘　　要：针对目前列装的单板码同步器功能检测和调试手段单一,难以满足多种型号箭遥任务的动态接收问题,提出一种新的、能适应各种型号箭遥信号解调的单板码同步器统调方法。在深入分析YH4系列码同步器鉴频、鉴相原理的基础上,对影响其动态性能的各个关键环节——码环基准时钟、匹配滤波输出通带电压、码元判决电平、输入信号电平和基线位置的检测和调试方法及工作机理都作了详细的阐述。A new adjusting method of single bit synchronizer is proposed for multifarious rocket telemetry dynamic receiving to resolve the lack of detecting measurement and adjustment at present.The principle of YH4 BSY's FM-PM demodulator is analyzed deeply in this paper,and the BSY loop clock,matching filtering channel's voltage,bit estimating level,signal level and baseline position which are keys to affect the dynamic characteristic are illustrated in detail.
