If the target waveform leads the reference waveform, phase is positive; if it lags,
negative.
Phase is not available in the Snapshot display.
Timing measurement. The ratio of the positive pulse width to the signal period,
expressed as a percentage.

Timing measurement. The distance (time) between  (default = 50%)
amplitude points of a positive pulse.

Timing measurement. Time taken for the leading edge of a pulse to rise from a
 ' value (default = 10%) to a  value (default = 90%).
Figure B–3 shows a rising edge with the two crossings necessary to calculate a
Rise Time measurement.
