General problems
Verify the test setup shown in
, 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 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 incorrect:
D1, D5 – N/A
D2, D4 – Flashing
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 was followed.
LEDs not flashing – reprogram 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 Device Manager of the computer, 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 the LED is not lit, press the Reconnect FTDI button.
Try restarting the configuration GUI.
Check default jumper connections as shown in
.
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,
ADS54J64_LMF_4841_mode01
must be selected.
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 correct in the HSDC Pro software.
Sub-optimal measured performance
Try pressing the Calibrate ADC button on the INTRO tab, to repeat 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.
