空间粒子辐射监测器用模拟信号源的实现

Design of an analog signal source for space particle radiation detector

空间粒子辐射监测器需要有模拟信号源在其生产和测试、试验阶段对其进行电性能检测,并随其辗转于各测试场地。使用进口模拟信号源存在操作复杂、设备笨重及只有单路输出等问题,因此需要设计一种专用模拟信号源。根据空间粒子辐射监测器的要求自行研制的模拟信号源有多路模拟信号输出,且各路信号幅度可独立调节,并采用内部电源供电。经过测试验证,该模拟信号源可作为空间粒子辐射监测器的配套设备使用,性能优于原进口模拟信号源,其电路设计亦可为相关设备提供参考。

For a particle radiation detector（PRD）,an analog signal source is required for testing its electrical properties,and for following the equipment around each test site.The available imported signal source can not satisfy the requirements for it is quite bulky,not easy for operation,and has only a single output channel.In this paper,an analog signal source is designed to replace the imported one.The new source is characterized by having multiple signal outputs,being independently adjustable for each output channel,and using an internal power supply instead of an external one.The new signal source can meet all the design objectives after verification by test,and enjoys less weight and a more compact volume than the imported source.
