DS2000A Upgrade Utility

DD4DA:
What is the reason why you don't support the DS2000 models too? There are none differents - they just uses some little hw changes - not more - the firmware they uses, are similar.

I had to use the memory range 1 to 33 million something as suggested by muxr.

Even at 300MHz and 2GS/s (1 ch), you have more than 6 samples per period, 3 times the Nyquist frequency. If you compute the worst case amplitude error you get with 6 samples per period, you will see that it is still very good...
I'm trying to find a function gen able to go up to 1 GHz in order to check the real bandwith at 3dB. I already made a measurement with a pulse generator and found 1ns rise time which gives a theorical BW of 350MHz, but I would like to confirm that with a sine wave above 300MHz.

 :-DD yep in your (our) dreams.

No seriously, if you want a pure 1 gHz sine 99 pct pure please post it
