AMSU-A VERIFICATION TEST REPORT METSAT PHASE LOCKED OSCILLATOR ASSEMBLY

摘要

Two Flight Model AMSU-A Phase Locked Oscillators (P/N 1348360-1, S/N F09 and F10) have been tested per AES Test Procedure AE-26758 Rev. C, which includes full functional testing, vibration testing, thermal testing, and AM/FM Noise testing. Both assemblies satisfactorily passed all performance requirements of the AE-26633 Product Specification.nDuring the manufacture of PLO F09, the DRO CCA lid was rotated 180 degrees, which rendered the unit unable to lock. After removing the 10 fastening screws and installing the lid in the correct orientation, the unit functioned to all specifications. During the vibration of PLO F10, the dielectric puck of the DRO was dislodged from its bonded attachment to the CCA. The PLO and DRO were opened, the puck was reattached, and the unit was restored to full operation. The MAI was enhanced to increase the reliability of the bonding.
