I was surprised that the measured rise time of the Keysight MSO-X-6104A from rx8pilot was significantly faster than mine.
He measured 70 ps and my instrument had measured 88 ps
So, I measured all my 4 channels again:
Scope-Channel, t-rise, Overshoot
CH 1, 88.6, 6.3%
CH 2, 87.9, 6.8%
CH 3, 82.7, 9.8%
CH 4, 83.2, 8.6%
Still about 12 to 18 ps slower than the rx8pilot data.
May be it is related to the overshoot.
Leo Bodnar:
I would like to buy another pulser from you but I would like you to make sure it has the smallest possible overshoot, like in the picture from rx8pilot or even less.
Is that possible that you pre-select one?
Or what do you think is the difference between the measurements of these two scopes?
