Show Phase Difference between Rx1 and Rx2

Quote from AdminTC on 27/01/2021, 09:50The 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.

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

Quote from azahit on 02/12/2024, 14:05I 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
