A Troubleshooting the DAC12DL3200EVM

Table A-1 lists some troubleshooting procedures.

Table A-1 Troubleshooting
IssueTroubleshoot
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 DAC configuration, click Instrument Options → Download Firmware and download TSW14DL3200_DAC_FIRMWARE.bin.
  • Power cycle the external power supply to the DAC EVM, and reprogram the LMK and DAC devices.
  • Ensure jumpers are set properly.
TSW14DL3200 EVM LEDs are not correct
  • Verify the installed jumpers on the TSW14DL3200EVM.

    JP2 pins 1–2, JP4 pins 2–3, and JP3 open.

  • Verify that the clock going to the CLK inputs of the DAC EVM are connected.
  • Verify that the DAC and LMK internal registers are configured properly.
  • Click Instrument Options → Download Firmware and download TSW14DL3200_DAC_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 DAC12DL3200.
HSDC Pro software is not sending data.
  • 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 DAC device mode selected matches the HSDC Pro ini file selected.
  • Check that the data rate parameter is correct. This should have a "M" for megahertz or "G" for gigahertz after the frequency number.
HSDC Pro software gives a time-out error when

User clicks on SEND.

  • Verify that the DAC data rate parameter is correctly set in the HSDC software.
  • Select Instrument Options → Download Firmware and download TSW14DL3200_DAC_FIRMWARE.bin. Try sending the test pattern again.
  • Verify both clocks are enabled, synchronized and the correct frequency going to the DAC EVM.
Sub-optimal measured performance
  • Make sure the DAC reset button was pressed before loading the DAC configuration file.
  • Ensure all SMA connections are secure.
  • Make sure FMC connectors are fastened together properly.
