Engineering tests 2018-Aug-17 and 18th (Billy Barott); summary of notes (see full obsnotes for detailed commands).
* Ran BF initialization and found that SPK daemons were down, which prevented init. On boot2, ran SPK daemon unload and reload commands. Cleared the error without incident.
* Ran the BF health check scripts from 2013; ran on BF1 and BF2, L and S band cals. Created lists of potentially-usable antennas. These antpols are:
* L-Band * [Bf1/ First run] 1ax,1ay,1bx,1by,1fx,1fy,1gy,1hx,2bx,2by,2dy,2ex,2ey,2fy,2jx,2jy,2kx,2lx,3ex,3ey,3jx,3jy,3lx,3ly,4gx,4gy,4jx,4jy,4kx,4ky,4ly,5cx,5cy,5ex,5ey,5gx,5gy,5hx,5hy
[BF1/ Second run] 1ax,1ay,1bx,1by,1dx,1dy,1fx,1fy,1gy,1hx,2ax,2ay,2bx,2by,2dy,2ex,2ey,2fy,2jx,2jy,2kx,2lx,2my,3ex,3ey,3jy,3lx,3ly,4ex,4gx,4gy,4jx,4jy,4kx,4ky,4ly,5cx,5cy,5ex,5ey,5gx,5gy,5hx,5hy
[BF2] 1ax,1ay,1bx,1by,1dx,1dy,1fx,1gy,1hx,2ax,2bx,2dx,2dy,2ex,2ey,2fy,2jy,2kx,2lx,2my,3ex,3ey,3jx,3jy,3lx,3ly,4ex,4gx,4gy,4jx,4jy,4kx,4ky,4ly,5cx,5cy,5ex,5gx,5gy,5hx
* S-Band * [BF1] 1ax,1ay,1dy,1fx,1fy,1gy,1hx,2ax,2ay,2bx,2by,2dx,2dy,2ex,2ey,2fy,2jx,2jy,2kx,2my,3ex,3ey,3jy,3lx,3ly,4gx,4gy,4jx,4jy,4kx,4ky,4ly,5cx,5cy,5ex,5ey,5gx,5gy,5hx,5hy [BF2] 1ax,1ay,1dy,1fx,1gx,1gy,1hx,2ax,2bx,2dx,2dy,2ex,2ey,2fy,2jx,2jy,2kx,3ex,3ey,3jy,3lx,3ly,4gx,4gy,4jx,4jy,4kx,4ky,4ly,5cx,5cy,5ex,5gx,5gy,5hx
Initialized all three beamformers with the antlist determined by the BF1 health check at L-band, and processed delay calibrations (30s on CASA).
Beamformers #2 and #3 displayed many link errors that were not cleared by firmware reinit or hardware reinit. Further attempt was to drop all antennas on related iBobs from the hookup (i9,16,22,24). This appears to have cleared the link errors on the main nodes; did not clear link alarms on B15.bfa (recently repaired unit), which shows ERCS alarms on three FPGAs. However, this might be sufficient for Foxtrot obs (doesn't use b15). After some time link error also showed on BF3 link to i21. Was not pursued further.
#========== CASA Stability Took 30 snapshots each of crosses and outputs on CASA with all 3 beamformers. Activity directories are about 8:41am…
