enabling/disabling RF front end

Post by beMet »

Hi everyone,

I am having an issue enabling/disabling the rf front end and hope you can give me some hints.

My setup is using hardware triggers to control rx samples. I need to capture repetitively (e.g. 200 times) samples (let's say ~100k) in sync with the trigger signal.
The approach is:
After each iteration, the RX trigger and front end are disabled. This clears the allocated buffer. Then the trigger is set up and the front end is enabled again -> next iteration. This method works fine for some applications.

However, I believe that disabled (or enabling) the front end also resets the local oscillator or something else. I cannot keep track of the phase of my signal over multiple iterations. Leaving away the disabling/enabling rf front ends, I can keep track of it, but then I struggle with the buffered data, as this data does not correspond to the current iteration.

Is there another way to clear the usb buffer or to enable rf front ends without loosing phase information?

Many thanks & best regards,
Bruno
