By the way, if you find the SMU instrument interesting, I wrote a detailed
article about what it is, and how it is

I had to generate that data by hand measurementstalk about tedious.
Your measurements confirmed what I saw as well: the ionization and
extinguishing voltages are pretty close to eachother. Generic neon bulbs
have much higher hysteresis.
I was not able to determine any significant difference
Thank you for making this test, Kevin! Nice to see the tubes passed :-)
It is interesting, that the current jumps from zero straight to milliamps
scale - theoretically there should be a small current (10E-5 - 10E-6 A)
flowing at the voltage close to the striking one (Townsend discharge). The

Greg: So far I haven't seen (and customers haven't reported) our tube to
drift with the striking voltage so much that it would not strike. I did
some random measurements on old tubes and after few seconds of normal use
(clock), all digits strikes at normal voltages. But we gave up on trying to
I had a difficult time trying to measure the striking voltage because it's
not consistent, perhaps because of random photons or background radiation.
It's very close to the sustaining voltage.
Also, I couldn't measure low current easily. I took data down to 500uA, but
below that the tube would
Thats amazing, it fits to the theoretical curve perfectly! Nice test, thank you!
