Increase frequency step size of the ASG
Posted: Fri Nov 15, 2019 5:00 pm
Hi,
I want to increase the step size (currently 116mHz) of the ASG. As a short test I divided the adc_clk, which is also connected to the ASG, by 128. With this I can output frequencies with a step size of ~8mHz. But using this approach, the clock of the acquisition module and all other modules is also reduced, what is not wanted. Is there a simpler solution that is not affecting other modules? Is it possible to e.g. run the ASG on a slower clock or do all modules need to run on the same clock due to synchronization?
I would be very thankful for any advice.
Thanks
