Hi all,
I was trying my Heathkit curve tracer on a gas discharge transient suppressor
(striking at about 200V) and I've found the following behaviour:

Basicly it seems to heavily ring on the turn-off curve?
This kind of devices should just show a two lines curve in theory.
My curve tracer appears to work fine on other less exotic devices (BJT,
zeners).
Can someone explain what is happening?
Thanks
