Period: Time between two consecutive, same-polarity edges of a repetitive waveform.
Frequency: The reciprocal of the period.
Rise time: Time needed for waveform amplitude rising from 10% to 90%.
Fall time: Time needed for waveform amplitude falling from 90% to 10%.
Rise delay: The delay time between the two rising edges of the primary and secondary signals.
Fall delay: The delay time between the two falling edges of the primary and secondary signals.
+Width: The width of a positive pulse at 50% amplitude.
-Width: The width of a negative pulse at 50% amplitude.
FRFR：Time from the first rising edge of source 1 to the first rising edge of source 2
FRFF：Time from the first rising edge of source 1 to the first falling edge of source 2
