Troubleshooting Tips
Verify the test setup shown in
Section 2
this document.
Check power supplies to the EVMs. Verify that the power switches are in the ON position
and supplies are drawing the appropriate current.
Check signal and clock connections to the EVM.
Check that all boards are properly connected together.
Try power-cycling the external power supply to the EVM and reprogram the ADC devices.
Verify the settings of the configuration switches on the TSW1400EVM.
Verify that the EVM configuration GUI is communicating with the USB and that the
configuration procedure has been followed.
Try capturing data in HSDC Pro to force an LED status update.
Verify that the TSW1400EVM 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, ADC08L060_cmos
should be selected.
Check that the analysis parameters are properly configured.
Check that the fundamental power is no larger than –1 dBFs.
Restart HSDC Pro and reload the firmware.
Verify that the ADC sampling rate is correct in the HSDC Pro software.
Measure test points to verify operating voltage ranges.
Verify the jumper configurations are in default locations.
Verify that filters are used in the clock and input signal paths and that low-noise signal
sources are used.
