This question is related to How do I use directional couplers on a differential signal? I understand that if I have an impedance mismatch at the end of a signal cable, E.G. from a terminator which ...
I understand how a directional coupler can be used to measure signals travelling in one direction on a wire. What I don't understand is exactly how this would work on a differential signal, E.G. LVDS ...
I may be able to get my hands on an old 600MHz LeCroy oscilloscope. However, it doesn't have any probes. Is it feasible to make an active differential probe for it using a high-speed op-amp, like the ...
