The next waveform display topic is measurements and statistics. Modern scopes have the ability to display measurements such as frequency, period, rise time, and fall time. This can be very useful in debugging electrical designs, giving the user additional insight into the circuit being tested. Some statistics may be seen on screen as well, including the minimum, the maximum, as well as the standard deviation and the mean value based on the number of measurements. LeCroy also does “All Instance Measurements”. For example, if there are nine rise times in the capture window and the rise time is measured, the mean value is the result of all nine rise times.
