5 Troubleshooting the ADC12DJ5200RFEVM/SEEVM

Table 5-1 lists some troubleshooting procedures.

Table 5-1 Troubleshooting
IssueTroubleshoot
General problems
  • Verify the test setup shown in GUID-38285161-FDB1-4D4B-AD20-905F3B927D26.html#SLAU7011280, and repeat the setup procedure as described in this document.
  • Check power supply to EVM and TSW14J57EVM. Verify that the power switch is in the on position.
  • Check signal and clock connections to EVM.
  • Visually check the top and bottom sides of the board to verify that nothing looks discolored or damaged.
  • Ensure the board-to-board FMC+ connection is secure.
  • Try pressing the CPU_RESET button on the TSW14J57EVM. Also try clicking Instrument Options → Reset Board after changing the ADC configuration.
  • Try power-cycling the external power supply to the EVM, and reprogram the LMK and ADC devices.
TSW14J57 LEDs are not correct
  • Verify the settings of the configuration switches on the TSW14J57EVM.
  • Verify that the clock going to the CLK input is connected and the appropriate LEDs are blinking.
  • Verify that the ADC device internal registers are configured properly.
  • If LEDs are not blinking, reprogram the ADC EVM devices.
  • Try pressing the CPU_RESET button on the TSW14J57EVM.
  • Try capturing data in HSDC Pro to force an LED status update
Configuration GUI is not working properly
  • Verify that the USB cable is plugged into the EVM and the PC.
  • Check the computer device manager and verify that a USB serial device is recognized when the EVM is connected to the PC.
  • Verify that the green USB Status LED light in the top right corner of the GUI is lit. If it is not lit, click the Reconnect FTDI button.
  • Try restarting the configuration GUI.
Configuration GUI is not able to connect to the EVM
  • Use the free FT_PROG software from FTDI chip and verify that the onboard FTDI chip is programmed with the product description ADC12DJ5200RF .
HSDC Pro software is not capturing good data or analysis results are incorrect.
  • Verify that the TSW14J57EVM is properly connected to the PC with a mini-USB cable and that the board serial number is properly identified by the HSDC software.
  • Check that the proper ADC device mode is selected. The mode should match in HSDC Pro and the ADC GUI.
  • Check that the analysis parameters are properly configured.
HSDC Pro software gives a time-out error when capturing data
  • Try to reprogram the LMK device and reset the JESD204 link.
  • Verify that the ADC sampling rate is correctly set in the HSDC software.
  • Try pressing the CPU_RESET button on the TSW14J57EVM. Also try clicking Instrument Options → Reset Board after changing the ADC configuration. Try to recapture again.
  • Select Instrument Options → Download Firmware and download 'TSW14J57RevE_16L_XCVR_ADCDDRDACBRAM.rbf'. Try to capture again.
Sub-optimal measured performance
  • Try clicking Cal Triggered/Running button 2× to re-calibrate the ADC in the current operating conditions. It is located on the Control tab of the configuration GUI.
  • Check that the spectral analysis parameters are properly configured.
  • Verify that bandpass filters are used in the clock and input signal paths and that low-noise signal sources are used.
