Error of WvBoardReadCaptureData: DUT Clock not detected by the firmware

bridget yu

The board works in NON-DESI mode. 2 signals are fed in both I+ and I- port on the board. I assume ADC works on 1.5Gsps and capture data on both of the 2 channels. The sample size is 16384.

Right after WvBoardReadCaptureData is called, such error is returned. However, if DUT clock is not detected by firmware, the error ought be returned earlier. Please share me your thoughts. Thank you very much!

The connection is:
---> I+ channel
signal generator ---> ADC LD BB ---> -----PC
----> I- channel

Hello Bridget,

Same as here, is this what you have resolved ?

Yes, thank you. Evros, may i ask what is the most fast acquisition you ever observed by using adc08d1520rb?

i did many times experiments and found each acquisition need at least 0.4seconds.

Have you tried to implement the control inside of fpga to achieve higher speed?

Thanks.

Can we let FPGA have default configuration and external trigger to control operation each time to achieve a higher speed?
