FAQ and Troubleshooting
G.1 Common Issues
The following section illustrates some of the common problems seen when attempting to use the EVM
hardware and software.
G.1.1 Issues
• Other Versions of Windows : Officially, the EVM software supports Windows 7 and Windows 10.
• Power supply capacity: It is likely that both the AFE EVM and the TSW EVM do not have a wall
power supply. Instead, they include the ability to connect to a bench-top supply via the provided cable.
It is critical that each of these EVMs has access to 2 A of current capacity.
• No Capture in HSDC Pro: It is possible that once the GUIs and EVMs are configured for capture, and
the capture button in HSDC Pro is pressed, that nothing seems to happen and eventually the GUI will
timeout and a pop-up an error appears as seen in
Figure 82 . Reasons for this can include the
following:
– Incorrect firmware loaded
– Current starvation on at least one EVM, 2 A is sufficient
– Missing Data output clock from the AFE to the FPGA. With LVDS, this could be the FCLK or DCLK.
D5 of the TSW1400 should turn on, and if not, this is probably the reason.
• Verify that the EVMs are mechanically mated correctly
• Verify power supply to both EVMs
• Verify jumper settings on the AFE EVM. Particularly inspect J54, J53, J57, J41, J40 and J42.
• Use an oscilloscope to test the frequency of the clock at header J40 or J42. This should be 40-
MHz.
• Even-odd channel swap observed with LVDS capture : Make sure that Switch 4 in S5 is in the "off"
position with LED D8 on. Ensure that there is no SMA cable connected to J37 on the AFE5832EVM
before retrying capture in HSDC Pro.
