Rise Time:
Time that the leading edge of the first pulse in the waveform takes to
rise from 10% to 90% of its amplitude.
Fall Time:
Time that the falling edge of the first pulse in the waveform takes to
fall from 90% to 10% of its amplitude.
+Width:
the width of the first positive pulse in 50% amplitude points.
-Width:
the width of the first negative pulse in the 50% amplitude points.
Delay 1
→
2 :
the delay between the two channels at the rising edge.
Delay 1
→
2 :
the delay between the two channels at the falling edge.
+Duty:
+Duty Cycle, defined as +Width/Period
-Duty:
-Duty Cycle, defined as -Width/Period
