Frequency
: Reciprocal of the period of the first cycle to complete in the waveform
Rise Time
: Time taken from lower threshold to upper threshold
Fall Time
: Time taken from upper threshold to lower threshold
+Duty Cycle
: Positive Duty Cycle = (Positive Pulse Width)/Period x 100%, Measured of the
first cycle in waveform.
-Duty Cycle
: Negative Duty Cycle = (Negative Pulse Width)/Period x 100%, Measured of
the first waveform.
+Pulse Width
: Measured of the first positive pulse in the waveform. The time between the
50% amplitude points
-Pulse Width
: Measured of the first negative pulse in the waveform. The time between the
50% amplitude points
