- When measuring, make sure you are using a high bandwidth, high-impedance probe, that is connected close to the receiver without any large wires on the signal probe or the reference connection.
- If you are doing all that, this glitch could also be crosstalk or ground bounce, so you may want to look into that as well.9 r# m% S* R0 _9 J& A
