Resolution: Done
Description
Purpose of this ADR is to achieve agreement and document desired MID CBF behaviour and details of the message exchange between OSO, TMC, SDP, CSP.LMC and MID CBF to a level sufficient for implementation.
Context: The MID CBF splits data into frequency slices that are ~200.0 MHz wide at the output of a frequency slice processor (FSP). Each frequency slice (FS) center is spaced ~198.2 MHz from the next FS center. This leads to an overlap of approximately 1.8 MHz or exactly 134.4 fine channels between frequency slices.
- Should the MID CBF send to SDP the fine channels from both frequency slices in the 1.8 MHz overlap regions?
- How does MID CBF provide to SDP the center frequency of the fine channel?
- How does MID CBF get told which channels to send to SDP (i.e., what is the band of interest)?
