|PAM4 doubles the number of bits in serial data transmissions|
by increasing the number of levels of pulse-amplitude modulation,
but does so at the cost of noise susceptibility

|Figure 1: By using exclusion triggering, the oscilloscope|
is prevented from triggering on the normal signal shape.
The trigger is set to capture only pulses with widths
different by at least 15 μs from the typical 325 μs.
On a digital oscilloscope, the persistence display mode is a little like the sustain pedal on a piano. When persistence display is selected, the oscilloscope will trigger, display the signal trace, then trigger again and add another trace to the display, and so on.
