I wasn't here for some time.
Lately I've purchased a Leo Bodnar 40ps pulser.
It is a very useful little gem, I like it very much!
Of course I've tested my HP1745A scope with it.
I've got about 130MHz bandwith on CH1, it is quite good I think.
However, I've got only 70MHz on CH2.
You can say, don't worry about it, then there is a 100MHz average.
Yet, I think I will check some things at CH2, someday.
Kind regards,
Gyuri
