Hello sszqdz,
Can you provide more information about your setup? How are you using the external triggers? What are you measuring? What are you correlating? Have you made successful measurements with both receivers? Does the data look good on both receivers? I’m not sure what you mean with the question “Using external trigger to collect IQ data can’t make sure collecting at the same time?” The presence of an external trigger does not synchronize the receivers, you still need to write code to use the trigger locations to synchronize the data streams.
I look forward to your response.
Regards,
A.J.
