Here is a odd thing I observing with B gate. Is this normal? Basically I
expect the pulse to be shortest at 1nS and gradually widen. What happens
here it basically goes in circles instead.
Looking at the width on your picture my B gate pulse width is correct at
1ns, corect at 2 and 5 but at 10ns us again the same length as 1nS and that
can't be right?
As far as I remember B-gate time stays the same from 1ns to 2ns (because of the reason I mentioned before) then increases at 5ns. I will look at what happens on my scope but I expect it should continue increasing.
