I have a 100MHz bus going from CPU to Memory. The routing length is about 2inches. So there is no termination. When I hook up the bus to a Logic analyzer, how do I know the Logic analyzer probes are not causing any reflection and messing up the bus signals. The length of the probe is about 40inches(1meter). The probes are connected to wires(~4inches) that are soldered to the bus traces on the PCB. What would be the right way to probe these signals.
