摘要

The RD-674A/UHN and RD-681/UHN Recorder Reproducers are Commercial off the Shelf (COTS) equipments that have been mechanically modified to allow the equipment to pass MIL-S-901D shock tests. All components in the recorders are readily available on the commercial market. The recorders contain a 586 microprocessor that operates at 133 MHz. They also contain 16 bit A/D and D/A converters for signal sampling and reproduction. Both of these components are found in the Military Critical Technologies List (MCTL) Section 5.5 Table 5.5-1 Microelectronics Militarily Critical Technology Parameters.
