Fall Time
The time span in seconds from when the waveform crosses the high reference level until it crosses the low reference level. The measurement starts at the left edge of the waveform and finds all high reference level crossings until a low reference level crossing. The final high reference level crossing is used in the calculation.
The reference levels are specified by Channel Based Low Ref and Channel Based High Ref, and their default values are 10% and 90%.
