The Design of Precision Signals Source Based on a Certain Radar Data Recorder
The Design Of precision Signals Source Based On a Certain Radar Data Recorder is introduced in the paper. Due to radar signal gather recorder equipments particularity, the article mostly introduced gather recorder equipment signal sources design. The choice of parts of an apparatus, hardware constitution and design of software of the precision Signals Source Based On a Certain Radar Data Recorder are recommended. In the paper, CMOS chips characteristic of ADG506 AND AD7945 is analyzed, and collectivity scheme of design and scheduling of CPLD is described in detail. According to data gather and records demand, the article put forward the designs scheme of modularize. It made use of CPLD as the systems center control logic, which improved the systematic flexibility. It introduced the design of hardware in every function module as well as key technology realized in detail 。Its main function modules include: center control logic module, low speed signal fountain D/A conversion circuit module, low speed signal fountain sampling keep magnify circuit module, high speed signal fountain clock signal difference output circuit module, high speed diver signal fountain differential strain wave magnify circuit module and power supply module. The developed signal source system can achieve the signals output such as control signals, analog signals, clock signals and so on, and achieve the function of power supply module.
