A Troubleshooting the ADC12DL3200EVM

Table 5-1 lists some troubleshooting procedures.

Table A-1 Troubleshooting
Issue Troubleshoot
General problems
  • Verify the test setup shown in Figure 3-1, and repeat the setup procedure as described in this document.
  • Check power supply to EVM and TSW14DL3200EVM. 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.
  • Make sure the board-to-board FMC connection is secure.
  • After changing the ADC configuration, click Instrument Options → Download Firmware and download TSW14DL3200_FIRMWARE.bin.
  • Power cycle the external power supply to the EVM, and reprogram the LMK and ADC devices.
TSW14DL3200EVM LEDs are not correct
  • Verify the installed jumpers on the TSW14DL3200EVM.
  • 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.
  • Click Instrument Options → Download Firmware and download TSW14DL3200_FIRMWARE.bin.
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.
  • Close and start 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 ADC12DL3200.
HSDC Pro software is not capturing good data or analysis results are incorrect.
  • Verify that the TSW14DL3200EVM is properly connected to the PC with a mini USB 3.0 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
  • Verify that the ADC sampling rate is correctly set in the HSDC software.
  • Select Instrument Options → Download Firmware and download TSW14DL3200_FIRMWARE.bin. Try to capture again.
Suboptimal measured performance
  • Click Cal Triggered/Running button two times to calibrate the ADC in the current operating conditions. The button 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.
