Waveform Parameter: Spike hysteresis

Full name: Hysteresis for end of waveform spike activity
Units: V or A/D
Range: [ -32767 A/D, 32767 A/D ]
Initial value: 0 A/D

Affects: all W.F. spike analyses, automatic generation of spike activity markers

When the associated waveform is searched for spikes, the spike measurement is controlled by the "Spike threshold", "Spike hysteresis", and "Spike discriminator". Any spike that crosses the threshold, does not exceed the discriminator level, and falls below the hysteresis, is treated as a valid spike.

The hysteresis is actually a displacement from the threshold, and will usually be negative (below the threshold), for detection of positive going spikes. If it is positive (above the threshold), the program will search for negative going spikes, which fall below the threshold, but not below the discriminator, then rise up above the hysteresis level.
