Possible GW Instek GDS-1000B hack
<< < (49/52) > >>
tatel:
There are contradictory reports about GDS1054B bandwidth on this thread. So I got one of Leo Bodnar's pulsers, just because curiosity got the best of me.

I tried the pulser on my improved GDS1054B. Used 50R inline termination. 1x attenuation. Capture is attached.

Since I'm not sure I did it all right,  if you have any suggestions, I will try to put in practice. I'm on a hurry now, I have to get out for some days, but I'll do once back at home
Fungus:
How old is your GDS1054B?

Maybe older ones "upgrade" better.

Got it on April, 19, 2021. You can see my report a few posts above this

2.8 ns risetime is 100MHz+ BW ... We can safely assume it is not 50 MHz anymore... You did unlock something...

I'd zoom in as far as possible to make sure the number is accurate.
