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:
Verify the settings of the configuration switches on the TSW14J56EVM.
D1, D2, D5 – N/A
Verify that the EVM configuration GUI is communicating with the USB and that the configuration
D4 – “Blinking”
procedure has been followed.
D8, D10, D17, D28 – “ON”
(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 the
Appendix A
.
HSDC Pro software is not capturing good data
Verify that the TSW14J56EVM is properly connected to the PC with a 3.0 USB cable and that the
or analysis results are incorrect
board serial number is properly identified by the
HSDC Pro GUI
software.
Check that the proper ADC device is selected. In default conditions, ‘ADS58J66_LMF_4841’
should be selected.
Check that the analysis parameters are properly configured.
Check that the fundamental power is no larger than –1 dBFs.
HSDC Pro GUI software gives a time-out error
Try to re-program the LMK device and reset the JESD204 Link.
when capturing data
Verify that the ADC sampling rate is correct in the HSDC Pro software.
Sub-Optimal measured performance
Make sure an ADC hardware reset was issued after loading the LMK but before loading the ADC
configuration file.
Check that the spectral analysis parameters are properly configured.
Verify that band-pass filters are used in the clock and input signal paths and that low-noise signal
sources are used.
