ASD／BLR及其测试平台的设计

Theory and testing of ASD/BLR

AND／BLR是稻草管探测器读出系统的核心电路,具有很强的功能,详细了解该电路的工作原理,是用好ASD／BLR的基础,对于采用稻草管探测器的读出系统是非常有意义的。给出了ASD／BLR的测试方法及其测试电路的原理。

This paper describes the testing theory and design considerations for a testing device of ASD/ BLR. This device includes pulse generator, signal drivers and signal receiver. In this device, input is fast pulse, its front edge only 2nS; its output is 32 channel digital signals. The module is designed with 61ayer PCB （printed circuit board）. ASD/BLR is the core of straw tube readout system. This chip has powerful signal process function which makes it very easy to use. One ASD/BLR chip can treat eight channels straw tube readout signals.
