SAADC on nRF7002 DK: limits for frequency and amplitude

[Raluca]

Hello, 

I am working with the analog-to-digital converter on the nRF7002 DK and I am trying to feed it with some signals (sinusoidal, triangular, etc) using a function generator. My quesntion is, which are the limits for frequency and amplitude that the board can support? 

Thank you and have a nice day!

Kind regards, 

Raluca

Hi, 

I tried to work with PuTTY, but after setting up all the parameters, the terminal would not open. Do you have a better tutorial on how to work with PuTTY?

I see. But then you just want to measure the signal generator, and not the nRF.

I don`t want to measure the signal generator, but I would like to look at the output values of the ADC. I was wondering if there is a way of visualizing the output of the ADC. 

Thank you!

You can refer to Testing and optimization. There are instructions for several populare terminals there, including PuTTY. I suggest you test with Hello World first, just so you know that you are using a sample that writes something to the terminal.

I see. Then an oscilloscope is not the tool you want. Just log the samples via UART and plot via your faviourite tool for souch tasks (like GNU Octave).
