problems may still arise because many oscilloscopes limit the bandwidth for high amplifications in order to reduce noise. These limitations are often drastic and can go down to 500 MHz for the highest amplifications. Since the D-PHY standard requires rise and fall time

of interest occurs much later than the transition from the LP to the HS state. The exact time needed for this is usually not specified by manufacturers but is typically in the range of several nanoseconds. Even if an overloaded amplifier does not affect the area of interest,

approach is that the amplifier in front of the A/D converter needs recovery time if operated outside its specified range. During this period, the energy stored in the amplifier causes signal distortions and makes results useless. Using this approach would only make sense if the signal
