Test the RAW IQ DLL Sample Rate

#1 · 13/06/2021, 19:45

A simple code example to test the RAW IQ DLL sample rate (incl. real and calculated error rate) is included in the latest RTSA Suite PRO SDK (and attached).

Simply copy the .exe to your RTSA-Suite PRO directory and execute it.

It should look like the following screenshot where you can see that the measured error rate is far below the calculated values (within brackets) proofing the excellent performance. The table shows:

Number of samples received so far
Milliseconds elapsed
Effective sample rate
Percentage of error of sample rate in relation to 92.16MHz
Margin of error of the error result

I tried to run your program, I get the following error message.

AARTSAAPI_Init failed : 8000000b

How to fix it?

thanks

Did you copy the .exe to your RTSA-Suite PRO directory when executing? 8000000b meaning AARTSAAPI_ERROR_MISSING_PATHS_FILE
