Show Phase Difference between Rx1 and Rx2

The Attached mission shows the phase difference/offset between Rx1 and Rx2 (RF1 and RF2). The mission includes a second SPECTRAN V6 to generate the test signal so please make sure to setup the right devices/serial number.

You can also use a different signal source instead. In this case simply remove the signal source SPECTRAN V6 from the mission.

Measuring the Phase Difference between Rx1 and Rx2

Thanks for this post. I understand that this mission will provide the phase difference in radian between Rx1 and Rx2.

Could you elaborate a bit on the IQ function "rotate" to extract phase difference.

Considering equi-amplitude signal, do you have any idea of the expected accuracy ?

Tks a lot

 

Rotate multiplies the first channel with the complex conjugate of the second, and divides by the norm of the second - thus inverse rotating the first by the second

I used the file that you shared on previous messages. Even I connect the cables that carries and transfer the same signal from signal generator, the phase difference is shown by the program is so unstable It's changing from -180 to +180 degree. Is there any way to measure the phase difference correctly?

I have another question also, I want to measure frequencies less than 30Mhz for example 15Mhz lets say. But I couldnt set up my center frequency as 15Mhz, it always wants to set center frequnecy as 2.440000 GHz.

How can I overcome these issues. Thank you for your support
