Description
With the completion of single-receptor (dual polarisation) testing according to the TDC MVP1 test plan https://docs.google.com/document/d/1js9GotiAZjzNFSav-br-vwgs24xtmOmLjqkGOoFIA9c/edit?usp=sharing, this feature looks to expand the testing to a multi-board (multi-receptor) configuration, and confirm end-to-end correlation with delay-tracking and resampling across multiple antenna.
This feature will build heavily on the predecessor feature SP-3277 which achieved single receptor resampling using single tones and delay tracked correlation between polarisations.
The integration risks that this feature will cover-off are:
- Board-to-board communication across the fibre-optic mesh using the SLIM links.
- Resampling multiple signals (from different BITE) to the same common frequency successfully and applying different independent delay models.
- SW Coordination between multiple boards.
- Removal of bulk delay in the ddr4 corner turner (where each receptor's BITE replay inevitably starts at different times).
The integration environment used will be the Python pyro-based Jupyter notebooks.

Of course we will diagnose and correct FW and signal processing behaviour anomalies as they arise.
