Tried to insert span zero schottky into aida2 correlation scalar, however rate was far too high.</p> <p>18:03 Removed span zero schottky signal, started new run 52.</p> <p>With beam ON we noticed some missing channels in the xy total plot. Aida 1 and 2 stat totals on spectrum browser show missing channels. Asic check on both to no effect. Fees power cycled.</p> <p>19:57 Started run 53. Currently waiting for beam</p> <p>21:20 Beam ON</p> <p>1*L plots checked for aida 1, several channels showed no data (noise)</p> <p>Slow comparator LEC threshold lowered to 0x32 to aida 1, checked 1*L plots and channels are now showing lots of noise. So those channels appear to be quiet using 0x64 threshold.
