Scope pictures triggering on sense wire C2
I set the scope threshold to below -14 mV based on previous measurements.
Scope pictures triggering on preamp output (pin 2)
I found that a trigger threshold of -100 mV discriminated well between noise and pulses consistent with previous ionization events.
