How to extend the AWG buffer size over 16384?
Posted: Thu Oct 11, 2018 7:17 pm
Hi everyone,
I want to use redpitaya to generate a chirp signal from 10KHz to 50KHz,
The way I think of this is to use the AWG function,
but unfortunately, the time resolution is not enough.
If I want the sweep time to be 100ms,
then the time resolution will be 100ms/16384 ~ 6us,
to the 10KHz side it will roughly have 100/6 ~ 17 points/cycle,
still can be called a good sine wave.
But for 50KHz the points drop to only 20/6 ~ 3 points/cycle,
which is very bad
So my question is, is there any possible to extend the buffer size, say, 1M points?
Any help will be appreciated!
