If the time is relatively short as compared with the complete signal period, an expanded
time scale (x10) should be applied. The ascertained time value is to be divided by 10 in
this case. When investigating the pulse behaviour of a signal voltage, the critical feature
is the rise time of the voltage step. To ensure that transients, ramp offsets, and
bandwidth limits do not unduly influence the measuring accuracy, the rise time is
generally measured between 10% and 90% of the vertical pulse height.
