Meas. type Symbol Description/result
High High High level of the displayed waveform - the upper maximum of the sample distribution, or the
mean value of the high level of a square wave without overshoot. The measurement requires at
least one complete period of the signal.
Low Low Low level of the displayed waveform - the lower maximum of the sample distribution, or the
mean value of the low level of a square wave without overshoot. The measurement requires at
least one complete period of the signal.
Amplitude Amp Difference between the top level and the base level of the signal. The measurement requires at
least one complete period of the signal.
Max Max Maximum value within the displayed waveform.
Min Min Minimum value within the displayed waveform.
Peak to peak PTP Difference of maximum and minimum values.
Mean Mean Arithmetic average of the complete displayed waveform.

RMS)
Standard deviation of one cycle, usually of the first, left-most signal period.
Crest factor Crest The crest factor is also known as peak-to-average ratio. It is the maximum value divided by the
RMS value of the displayed waveform.

N.OS
Overshoot of a square wave after a rising or falling edge. It is calculated from measurement val-
ues top level, base level, local maximum, local minimum, and amplitude.
