Table 5-1. Troubleshooting
•
Verify the test setup shown in
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.
•
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
•
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.
•
Use the free FT_PROG software from FTDI chip and verify that the onboard FTDI chip is programmed
with the product description ADC12DJxx00RF .
•
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.
•
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.
•
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.
