Can the difference in spectrum between Rx1 and Rx2 be displayed?
A user is looking to subtract the spectrum measured using one type of antenna, from the spectrum measured with another antenna, in real time.
Is it possible to make a differential RF spectrum measurement between the two inputs of the RSA2000X?
Or would this be possible using two RSA250X?
You can easily see the delta in the Spectrum view by connecting both Spectrans and using the "Reference Trace" setting in the view menu:
Yes you can see both spectra of Rx1 and Rx2 at the same time (even in sweep mode) since those blocks all offer two inputs.
You can even subtract them from each other: https://v6-forum.aaronia.de/forum/topic/spectrum/
Even displaying the phase difference between Rx1 and Rx2 is possible: https://v6-forum.aaronia.de/forum/topic/phase-difference-measurement-between-Rx1-and-Rx2/
