Regarding the phase calibration problem of CN0566, phaser_examples.py

Thread Summary

The user encountered a phase calibration issue with the phaser_examples.py file, where one channel had a large phase offset. The support engineer explained that this is normal due to the phase mismatch between the two separate signal paths involving the 4th and 5th elements, ADAR100s, mixers, and filters, and suggested measuring and compensating for it during normal operation. The user confirmed that manual calibration adjustments led to good results.

Hello,

When I ran the phaser_examples.py file, we encountered a phase calibration problem. Here is the result after running it:

Orange is -95, the third element

After comparing with the experiment manual, the following figure is the phase calibration image in the experiment manual.

We would like to ask, after this phase calibration, why does one channel in our experimental results always have a very large offset?

This is the result of manually adjusting the calibration parameters in the past few days. It would be great if its built-in calibration can be similar to this.
