    In this video, you'll learn how to capture a tone from the AFE74xx EVM with the TSW14J57 EVM using HSDC Pro. For more details, visit TI.com/AFE74xx.

    In the previous video, I demonstrated how to program the AFE74xx EVM in decimation mode 4, and send the tone from the TSW14J57. If you were continuing from the last video and were able to successfully generate the two-tone output on the AFE, your ADC has already been configured in mode 4. If you have not yet set up the hardware or verified the DAC output, please visit the video's hardware setup and sending a tone to the DAC before continuing with this video.

    Let's get started. After the GUI is done programming the AFE74xx EVM and the DAC output has been verified, navigate to the ADC tab in HSDC Pro. Select the INI file titled AFE74xx_RX_mode4. Enter the data rate of 737.28 mega samples per second. This is derived from dividing the ADC clock of 2,949.12 mega samples per second by mode 4's decimation factor-- 4. Turn on the signal generator and press Capture.

    If you do not get a capture, navigate back to the AFE GUI. In the Advanced tab click on the button located next to the word ADC. This will manually re-adapt the SYSREF receiver, manually reset the JESD 204B core, and force the re-handshake of the JESD 204B link. Then go back to HSDC Pro and click Capture. The tone should be centered at 200 megahertz.

    Why 200 megahertz? The default RX NCO value is set to 1,700 megahertz. So with the input signal being 1,900 megahertz, the signal is down converted to an IF frequency of 200 megahertz before it's captured by the J57.

    To learn more about how to configure the NCOs, head over to watch Operating the AFE74xx GUI-- Configuring the NCOs. Visit TI.com/AFE74xx to learn more about the AFE74xx or to purchase so you can follow along with this video series. Thanks for watching.
