Part Number: PGA970EVM

Hi ti team,

I work at present on pga970 and I generate a signal sine from the WAVEFORM RAM, it's good.

For the suite, I would like I could get back the signals which are on s1 and s2 to digitize them and visualize them on the window ADC Capture of the GUI.

Please find attached my configuration :

Thanks team ;)

    Hello,

    You will need to enable DEMOD1, the Test Mux, and the Interfaces & Deci Clk as well as the VCM before you can read the ADC data. Please set up the ADC window as shown below, then you will be able to read ADC data in real time using the ADC Capture page.

    Regards,

    Thank you in advance.
