TROUBLESHOOTING

This section provides recommendations on how to prevent and
troubleshoot problems encountered with the software and the

hardware.

SOFTWARE

Follow these recommendations for the evaluation software:
•
Always install the software prior to connecting the
hardware to the PC.
•
Always allow the install to fully complete (the software
installation is a two-part process: installing the ADC software
and the SDP drivers). This may require a restart of the PC.
•
When first plugging in the SDP board via the USB cable
provided, allow the new Found Hardware Wizard to run.
Though this may take time, do this prior to starting the
software.
•
If the board does not appear to be functioning, ensure that
the ADC evaluation board is connected to the SDP board
and that the SDP board is recognized in the Device
Manager, as shown in Figure 16.
•
If connected to a slower USB port where the SDP board
cannot read quickly, a timeout error may occur. In this
case, it is advised not to read continuously or, alternatively,
to lower the number of samples taken.
•
Note that when reading continuously from the ADC, the
recommended number of samples is up to 1,048,576.

HARDWARE
If the software does not read any data back, take the following steps:
•
With the 12 V wall wart plugged in to the SDP board, check
that the voltage applied is within the ranges shown in Table 3.
•
Using a digital multimeter (DMM), measure the voltage
present at 12 V and the VADJ test points, which should
read 12 V and 2.5 V, respectively. The +12V_FMC LED of
the evaluation board and the LEDs of the SDP board
(FMC_PWR_GO, SYS_PWR, FPGA_DONE, BF_POWER,
LED0, and LED2) should all be lit.
•
Launch the software and read the data. If nothing happens,
exit the software.
•
Remove the 12 V wall wart and USB from the SDP board,
and then reconnect them and relaunch the software.
•
If an error occurs, check that the evaluation board and the
SDP board are connected together so that the evaluation
board is recognized in the Device Manager, as shown in
Figure 16.
Note that when working with the software in standalone/offline
mode (no hardware connected) and later choose to connect
hardware, first close and then relaunch the software.
