Hi, 

 

I have an AD9648 + HSC-ADC-EVALCZ setup and want to sample complex IQ data into C# using library HadBoardApi.dll. From some Matlab examples found in this forum I could find my board using code. 

 

Now I have the following questions: 

1. Which FPGA file under C:\Program Files (x86)\Analog Devices\VisualAnalog\Hardware\HSC_ADC_EVALC shall I use to program the FPGA? 

2.  How can I sample IQ data? It is mentioned here https://ez.analog.com/thread/15016 that "I think the maximum number samples you can capture from each channel is 32K in this mode.  Please note that the channel numbers are swapped...channel A is 2 and channel B is 1". Could you please elaborate how the IQ data are interleaved and the AB channels are twisted?  

3. Is there a complete piece of sample code based on HadBoardApi.dll to achieve the my complex IQ sampling task? 

 

Thanks a lot in advance and best regards,

Peng
