How to control ADAS3022?

Marcel:

I moved this to the Precision ADC community - they might be able to help you out with the ADAS3022 eval software.

Hi,

Our evaluation software are provided as is. You may opt to implement changes with the software however we do not provide support on that.

Hi,

I just checked the evaluation software and you actually have the option to change the throughput as well as set the sequencer operation for scanning channels. What do you mean by "in a different time cycle," do you want to test it at different clock speeds? If so, you will have to edit the software as I mentioned in my previous reply.

Hi,

The aim is to test the ADAS3022 using multiple inputs at the same time, using a personalized throughput, setting different PGIA for each input and plotting all of them in the same graph, where I could set the horizontal span to samples/time. However, the evaluation software just allows me to plot one input at the same time, with the same PGIA for all of them, etc.

Hi, Marcel.

The PGIA gain can be different per channel or per pair when the advanced sequencer is enabled.

Hope this helps.

Hi Karen,

Thank you very much for your response. I would like to ask a few more questions about that.

I got the next result:

The input is a Sine Wave 1KHz frequency and 4.9V amplitude. I obtained 50 samples per period.

I got an invariable throughput value of 12.213Ksps. If I divide 50samples/1msec (period of sine wave) I obtain 50Ksps which means that it should be sampled at this throughput. In addition, I can not change the throughput value.

Thanks in advance
