Procedure

1. Under the Analog and Clock tab, toggle Dither Enable to the on position and set Dither Amplitude_1 to 3.
2. In the Bypass Mode box, use the DDC dropdown to change to Complex Mode. You will notice that the box title changes to Complex Mode to reflect the current DDC operating mode. Press the Home Button to change back to the home screen.
3. Set Average to 2x and change ADC Mode to Dual with averaging.
4. Use the Decimation dropdown to change the decimation to 128.
5. Set the LMFSHd setting to 1-4-8-1-0.
6. Set the channel INB1 NCO0 and NCO1 to 1000 (MHz).
7. Change LMK divider from 8 to 32.
8. Once these settings are verified and match Figure 4-5, press the Device Bringup button.

9. Wait until after the message Device Bringup Completed appears in the Log.
10. In HSDC Pro, connect to the TSW14J58EVM and select ADC32RF5x_1481_1p5G-2G as the INI file shown in Figure 4-6 below.

11. Update the firmware by pressing Yes on the pop-up window and waiting for the Downloading Firmware message to finish.
12. Open the Additional Device Parameters menu by clicking on the gear next to the ADC Output Data Rate field.
13. Check the tickbox labeled "Enable?" and then enter the parameters shown in Figure 4-7 below.

14. Once completed, press OK.
15. Check the tickbox labeled Auto Calculation of Coherent Frequencies and the user will see the ADC Input Target Frequency change from 1.003G to the coherent frequency. Set the signal generator connected to the channel B input to this coherent frequency.
16. Change the view window from Real FFT to Complex FFT and select channel 3/4.
17. Press the Capture button. You should now see something similar to Figure 4-8.
18. Adjust signal generator output such that the measured fundamental power in HSDC Pro is at the user's desired level.
