Hello, Evan,
I really don't know what the setup is. I do know that it is to generate
a timed, high energy pulse but due to COVID-19 and working at home, I am
not deeply involved in that phase of the project. It is in the hands of
an engineer (Not Electronics).
Some discussion was brought up about simulation issues in Multisim in a
teleconference and I thought I would ask the list. From teleconference
today, information that members of this group provided have been helpful
but I don't know in what way.
