I know basis configuration of residual phase noise measurement. How it can be use with E5052B Signal Source Analyzer. How the connection should look (block diagram)? What the settings should be set to measure that parameter.
I know that the measurement should be done on baseband. The E5052B have two jumpers in front, for direct access. Should they be use for the residual phase noise measurement and how?
Still not getting any response.
Let me add add couple questions and ideas.
The E5052B contains two Phase Noise receiver and baseband access to at list one of the receiver - that very interesting configuration.
Can we use the two Phase Noise receiver for Residual Phase Noise measurement?
The Residual Phase noise Measurement in most cases required to measure in parallel two DUTs to cancel common distortion coming from RF source and/or power supply. From the spec for E5052B we can see explanation why the second receiver was introduced. The mein idea is to use correlation to improve overall dynamic range of the system.
In our case the correlation probably is not as important as cancellation of common signals for system that work in parallel.

Here is the idea:
1) Connect the DUTs to both receiver
2) Read the Phase Noise from both receiver
3) Use math to cancel common signals
4) Extract the Residual Phase Noise
Fig. 2 propose Residual Phase Noise measurement setup using E5052B Signal Source Analyzer.
Required access to Phase Noise data from each Phase noise receiver - right now we can't see the data for both receivers. Because math is done in software, external phase shifter are not needed for the quadrature - wide band operation.
Look like relatively simple to implement with existing setup with minimal firmware modification.
I am aware that I probably missing tone of issues, I just wonder if that could work.
Any input welcome.
