Hi All,
I was playing with some coils and one of them had the damping resistor not perfectly adjusted, showing a spike. I had the idea to bring a target close to the coil (1 square inch aluminium foil), to see what happens with the spike and with the pulse width. The pulse width became slightly larger (as if I were decreasing the damping resistor value), and the spike decreased significantly. The idea I have is to use a coil that has a pretty large width of the pulse, that would allow me to take two samples on the horizontal portion of it. At the moment, my HH can't set the samples so close to 0us. The second sample can even be before the spike (that would make it actually the first sample).
Regards,
Nicolae
