空間粒子輻射監(jiān)測器用模擬信號源的實(shí)現(xiàn)

Design of an analog signal source for space particle radiation detector

  • 摘要: 空間粒子輻射監(jiān)測器需要有模擬信號源在其生產(chǎn)和測試、試驗(yàn)階段對其進(jìn)行電性能檢測，并隨其輾轉(zhuǎn)于各測試場地。使用進(jìn)口模擬信號源存在操作復(fù)雜、設(shè)備笨重及只有單路輸出等問題，因此需要設(shè)計(jì)一種專用模擬信號源。根據(jù)空間粒子輻射監(jiān)測器的要求自行研制的模擬信號源有多路模擬信號輸出，且各路信號幅度可獨(dú)立調(diào)節(jié)，并采用內(nèi)部電源供電。經(jīng)過測試驗(yàn)證，該模擬信號源可作為空間粒子輻射監(jiān)測器的配套設(shè)備使用，性能優(yōu)于原進(jìn)口模擬信號源，其電路設(shè)計(jì)亦可為相關(guān)設(shè)備提供參考。

     

    Abstract: 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.
