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 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 ADC12DJxx00RF .
|
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 recalibrate 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.
