Hi Varsha, Can you confirm CS is connected to JA-2, CLOCK is connected to JA-7, and MOSI is connected to JB-6? They are labeled pretty clearly on the EVM board, but just want to double check: Can you measure one of the SPI write frames on the scope and share a screenshot so I can check the SPI format and timings? Share what command you are intending to send for that write so I can double check. It's likely that your data is shifted incorrectly and is causing the DAC to interpret the data incorrectly. Can you share the full DAC command you sent for the results in your table? Best, Katlynne Jones
