2.4 Troubleshooting the TRF1108-DAC39RFEVM

Some troubleshooting procedures are shown in Table 2-5.

Table 2-5 Troubleshooting
IssueTroubleshoot
General problems
  • Verify the test setup is similar to Figure 2-1. Repeat the setup procedure as described in this document.
  • Check power supply to EVM and TSW14J59EVM. 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.
  • Press the CPU_RESET button on the TSW14J59EVM. Try clicking Instrument Options → Reset Board after changing the DAC configuration.
  • Try power-cycling the external power supply to the EVM, and reprogram the DAC, LMX and LMK devices.
TSW14J59EVM LEDs are not correct
  • Verify the settings of the configuration switches on the TSW14J59EVM.
  • Verify that the clock going to the CLK input is connected and the appropriate LEDs are blinking.
  • Verify that the DAC device internal registers are configured properly.
  • If LEDs are not blinking, then reprogram the DAC EVM devices.
  • Try pressing the CPU_RESET button, on the TSW14J59EVM.
  • Try clicking SEND button in HSDC Pro again.
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 yellow EVM Status LED light in the lower right corner of the GUI is on. If the light is not on, then try restarting the GUI and reconfiguring the devices.
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 ADC12DJxx00RF.
DAC output looks incorrect, distorted or there is no output
  • Verify that the TSW14J59EVM is properly connected to the PC with a USB-C cable and that the board serial number is properly identified by the HSDC software.
  • Check that the proper DAC device mode is selected. The mode must match in HSDC Pro and the DAC GUI.
  • Check that the configuration parameters are properly configured.
  • Select Instrument Options → Download Firmware and download 'TSW14J59REVB_DAC_64B66B_FIRMWARE.bit'. Try to send again.
  • Verify J13, J17, J14, J18 are installed correctly.
Output power looks low
  • Check that the spectrum analyzer is set to proper settings.
  • SMA connector is properly connect to the DAC output and Spectrum analyzer.
  • Verify J13, J17, J14, J18 are installed correctly.
