| * Measurements of electrical peak with the oscilloscope during an on-off measurements with the offsets in elevation (scan 53). No correlation was found between the beginning of the scans where the extra noise peaks appeared and the electric activity. A peak frequency of 5 sec was observed but which may be related to the air conditioned system. |
Tests performed during the heavy maintenance (2007.06.20)
Goals
Identify the origin(s) of the "acceleration" problem in MAMBO2
