2.4 Quick Start Trouble Shooting
Use Table 2 to assist with problems that may occur during the quick start procedure.
Table 2. Troubleshooting Tips
Issue Troubleshooting Tips
General Problems Verify the test setup shown in Figure 2 and repeat the setup procedure as described in this document
Check power supplies to the EVM and TSW14J56EVM. Verify that the power switches are in the ON
position
Check signal and clock connections to EVM
Check that all boards are properly connected together
Try pressing the CPU_RESET button on the TSW14J56EVM
Try power-cycling the external power supply to the EVM and re-program the LMK and ADC devices
TSW14J56 LEDs are
not correct:
D1, D5 – N/A
D2, D4 – Blinking
D3, D6, D7 – OFF
D8, D28 – ON Verify the settings of the configuration switches on the TSW14J56EVM
Verify that the EVM configuration GUI is communicating with the USB and that the configuration
procedure has been followed
(LEDs Not Blinking) Re-program the LMK device
Try pressing the CPU_RESET button on the TSW14J56EVM
Try capturing data in HSDC Pro to force an LED status update
Device GUI is not
working properly Verify that the USB cable is plugged into the EVM and the PC
Check the computer’s 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, press the
Reconnect FTDI button.
Try restarting the configuration GUI
Check default jumper connections as shown in Appendix A
HSDC Pro Software is
not capturing good
data or analysis
results are incorrect Verify that the TSW14J56EVM is properly connected to the PC with a mini-USB cable and that the board
serial number is properly identified by the HSDC Pro software
Check that the proper ADC device is selected. In default conditions, ADC31JB68EVM should be
selected.
Check that the analysis parameters are properly configured
HSDC Pro Software
gives a Time-Out error
when capturing data Try to re-program the LMK device and reset the JESD204 link
Verify that the ADC sampling rate is correct in the HSDC Pro software
Sub-Optimal Measured
Performance Try pressing the Calibrate ADC button on the INTRO tab of repeating the configuration GUI procedure
for programming the EVM
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
