Story Details

VE-175: Troubleshoot Coherent Mode Data Artifacts

Ryan, Randy, and Jason seem to have traced the source of the artifacts to overflow in an early stage of the FFT. We found some values of fftshift that reduce the overflow rate to a near-zero level and nearly eliminated the artifacts. Ryan also traced the source of the overflow to strong RFI at 1100, 1600, and 1800 MHz.

VE-173: Move VEGAS Test Environment to Equipment Room

Has been moved. Laura and Jason are trying to determine ownership of a ROACH2 used for the FAST backend to see if it can be used in a test environment.

VE-174: Final Release Notes

Ryan has one minro comment from Justin to incorporate. Changes to vegas.conf are self-documenting and will not be included.

VE-164: Manager stability issues

No updates.

VE-156: Review high time resolution modes

No updates.

VE-179: Create Spectral Line PFB Component

In progress. Will continue into next sprint.

VE-171: Update SRBS

No comments

VE-163:

VE-170: Document plan/requirements for test environment

Moved to the next sprint.
