Abstract : Vibration testing was conducted to determine the recording characteristics of the recorder when mounted with and without isolators and subjected to a vibration environment. The vibration test program was conducted in 5 phases. Test Phases 1, 3, 4, and 5 were conducted with the specimen mounted to the vibration fixture via vibration isolators and test Phase 2 was conducted with the specimen rigidly mounted to the vibration fixture. Low-level (2g peak) sine survey tests (with the tape recorder not operating) were conducted on the tape recorder during test Phase 3, and full-level (10.5g) random vibration tests (with the tape recorder operating) were conducted on the tape recorder during test Phases 1, 2, 4, and 5.
