Hi Rob, Thank you for the detailed troubleshooting steps. The 100 MHz oscillator is on board and powered up. I have measured on pin 44 of the LMK (Oscin_n) and confirm that the clock input is present: 2. Using the GUI, I performed a global power down of the board, and this does not change the current consumption at all (still at 468 mA), although the checkbox gets selected and the ADC register 0x15 read operation gives value 0xFF. 3. Also, as a simple test, I perform a 'Read All' operation in the low-level view after restarting the GUI and power cycling the ADC board, and the GUI returns 0xFF values for all registers of the ADC and the LMK. After this, I am not able to change any setting or write directly to any register address in the GUI. Since it is evident that the GUI is unable to communicate with the ADC and LMK, could you suggest any additional debugging steps? I am using the ADC3000 GUI version 1.2 (build date: 02/23/2022). Is there a later version of the GUI available? Regards, Sukhdeep
