Intended where the shape of the missing tooth gap creates an undefined zero-crossing curve. Found on some Renaults with 60-2 triggers for example.
In the Trigger logger, it looks like there are 2 missing gaps where the sizes can vary with RPM.
Note: that this pattern can also be generated by incorrect polarity settings of a normal Missing tooth trigger, make sure the polarity is correct before resorting to using this mode)
Instead of a sharp zero-crossing this looks like a pulse of one polarity followed by another of the positive polarity with a slow curve between them.
The bipolar missing teeth trigger system is found in Inputs --> Trigger/Home inputs, advanced trigger options.
