您的信号衰减可能是由于PXI/PXIe-2532 所使用的TB-264X系列接线盒造成的,后者的行列间有保护电阻的存在。NI提供这些电阻是为了保护继电器不受电容负载上的励磁涌流影响。
所以,您需要在产品选型时就指出接线盒是否需要包含保护电阻:任一TB-264X系列接线盒的行端均有保护电阻,而列端是否包含是可选的。若要旁路行端的保护电阻,可以通过在接线盒上的“行保护电阻旁路孔”(Row Protection Bypass sockets)上加2X1跳线,随后,通过检测可以看到信号衰减减少。
可以在Knowledge Base: document What Are the Optional Isolation Resistors of the TB-264x Series? 中获得有关保护电阻的更多信息,下附链接。
