Maximum
Amplitude (voltage) measurement. The maximum voltage. Typically the most
positive peak voltage.

Mean
The arithmetic mean for one waveform. Remember that one waveform is not
necessarily equal to one cycle. For cyclical data you may prefer to use the
cycle mean rather than the arithmetic mean.

Timing measurement. The ratio of the negative pulse width to the signal
period expressed as a percentage.
