Waveform Parameter: Cycle threshold

Full name: Threshold for start of waveform cycle activity
Units: V or A/D
Range: [ -32767 A/D, 32767 A/D ]
Initial value: not set

Affects: automatic generation of cycle activity markers

When the associated waveform is scanned for cycle activity, the cycle measurement is controlled by the "Cycle threshold", "Cycle hysteresis", and "Cycle crossing delay". Cycle activity starts when the waveform rises above the threshold, and ends when it falls below the hysteresis level. Each half-cycle (active phase or inactive phase) must be at least as long as the "Cycle crossing delay".

The hysteresis is actually a displacement from the threshold, and will usually be negative (below the threshold), for detection of positive going activity. If it is positive (above the threshold), the program will search for negative going activity, which falls below the threshold, then rises up above the hysteresis level.
