对数字芯片而言，仅知道有高低电平的输出变化，但无法查出它的上升和下降沿的变化速度。 
4. 对于模拟芯片，它处理的是模拟的变化量。其受电路的元器件的分布，解决信号方案的不同的影响，是错综复杂的。就目前的在线测试技术，要解决模拟芯片在线测试是不可能的。所以，这项功能测试的结果，仅能供参考。 
5. 大多数的在线测试议，在对于电路板上的各类芯片进行功能测试后，均会给出“测试通过”或“测试不通过”。那么它为什么不给出被测器件是否有问题呢？这就是这类测试仪的缺撼。因为在线测试时，所受影响（干扰）的因素太多。要求在测试前采取不少的措施（如断开晶振，去掉CPU和带程序的芯片，加隔离中断信号等等），这样做是否均有效，值得研究。至少，目前的测试结果有时不尽人意。
