The Generator arrive today from USA to my Argentine door!!! .
Unfortunately not work fine.
Rt=1,67nS (instead 300pS)
Width pulse= 5,84nS (wave exponential decay instead rectangular pulse)
Max out= 3,5V (instead 25V)
Rep Rate=15Mhz (instead 50 or 100Khz)
The ratio of different att step, seems to be good.
Probability arise that my previous intuition about bipolar avalanche transistor burned out come truth.
Perhaps the out pulse I see is not else than the trigger pulse passing trough a short avalanche transistor.
Any way, this nice generator will be fixed (tomorow)....all kind of help & advice will be welcome.
Gabriel.

Here the link to this almost new pulsed generator, at first glance is a
transmission line pulser with 300ps ..but no model or number at all.
I just brought it with the hope work right...but a good service manual
will be very appreciated and gratefully.
