Title: DDS AWGs in practice, reconstruction filter. Rigol DG800/900 in particular.
Post by: n3mmr on May 22, 2019, 07:02:01 am
I watched a YT video from RigolTech, purportedly explaining the advantage of l6 bit vs 14 bit digital waveforms.

It was very short, not very illuminating and the oscilloscope screens used raised a question:

Don't the DG800/900 series AWGs have reconstruction/anti-aliasing filters after the basic DAC?

I hope they do...
