Sample Position
Sample position is a point within a bit’s time. The oscilloscope samples the bit level
at this point. The sample position is represented by the proportion of "the time from
the start of the bit to the sample position" to the "bit time", as shown in the figure
below.
One Bit
60%
70%
80%
