Basic Test Procedure with TSW1400
Figure 12. Load File to Transfer into TSW1400
4. Select the file "WCDMA_TM1_complexIF30MHz_Fdata307.2MHz_1000.tsw" under C:\Program
Files\Texas Instruments\High Speed Data Converter Pro\1400 Details\Testfiles. The data rate of the
file selected will depend on the sampling rate and interpolation ratio of the DAC configuration.
5. Enter 307.2M for the "Data Rate" and 2's complement for the "DAC Option".
6. Select Hanning for "Window".
7. In the “DAC Selection” panel on the left side of the GUI, click on “Send” to load the data into memory.
8. Toggle the SIF SYNC button of the DAC348x EVM GUI to synchronize the appropriate digital
blocks, if the example file with NCO setting is used.
9. Verify the spectrum using the Spectrum Analyzer at the four IF outputs of the DAC348x EVM (J7, J6,
J3, and J2).
?
For the DAC3482 EVM, the IF outputs are at the J6 and J3 SMA connector
10. The expect results are shown in Figure 13 (NCO enabled at 30MHz) and Figure 14 (NCO disabled).
