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's. Verify that the power switches are in the ON position
and supplies are drawing appropriate current.
Check signal and clock connections to the 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 reprogram the LMK and ADC
devices.
TSW14J56 LEDs are not correct:
Verify the settings of the configuration switches on the TSW14J56EVM.
D1, D5 – N/A
Verify that the EVM configuration GUI is communicating with the USB and that the
D2, D4 – Blinking
configuration procedure has been followed.
D3, D6, D7 – OFF
(LEDs Not Blinking) Reprogram the LMK device.
D8, D28 – ON
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
Reconnect FTDI
button.
Try restarting the configuration GUI.
Check default jumper connections as shown in
Appendix A
.

results are incorrect.
Check that the proper ADC device is selected. In default conditions, ADS54J60_LMF_8224
should be selected.
Check that the analysis parameters are properly configured.
Check that the fundamental power is no larger than -1 dBFs.

Verify that the ADC sampling rate is correct in the HSDC Pro software.
Sub-Optimal Measured
Make sure an ADC hardware reset was issued after loading the LMK but before loading the
Performance
ADC configuration file.
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.
