Possible GW Instek GDS-1000B hack
Gazmon:
What about the 200mhz bandwidth
Mortymore:
If the scope says now it's 200MHz you can start to be confident that it is.
But you could check that if, for instance, you have access to a know source that achieves the 200MHz, or to a fast pulse generator, with a rise time of at least 1.75ns
RiseTime (nS) = 0.35 / Bandwidth (GHz) so for a BW of 0.2GHz (or 200MHz), the RT = 0.35/0.2 = 1.75 nS
Just for reference see the specs of the 2000E series, and observe the relationship between BW and RT
There's a TDR pulse generator video that is very popular, from a forum member w2aew, but I think it may be not fast enough to test the 200MHz
But don't forget what oscilloscope probes (or test leads) you are using, because they must be suited for those 200MHz. Try to find intel on your probes, since there's cases were they say they'r good up to 100MHz but they are fine even above 200MHz. The probes must not be the limiting factor.
Gazmon:
Ok cheers , I only have a feeltech 3200 24 mhz Sig gen , so don't think I can test it fully
And my probes are 100mhz I might need to upgrade them to be sure?
Gazmon:
Just a note on the 200mhz upgrade
It could be just the software telling me this, and the hardware may not support anything above 100mhz? as I cannot fully test it at present I cant confirm its really gone 200mhz, but be nice if it was confirmed
In Bandwidth options I now have `20mhz 100mhz+Full`
Where before it was only 20mhz and full
slodat:
Does anyone have 1.12 they would be willing to share with me? I have a GDS-1054B.
Thanks in advance!
