3.5. System Attributes
3.5.1. Reliability
All design aspect of this module shall be maintained within Agile along with all supporting
documentation and data sheets for future reference.
Maintenance of, Manufacturing, Re-design, Approvals and Testing and continuous improvement shall
fall within the requirements of the quality control system.
3.5.2. Availability
P.O.S.T and ongoing system checks should be employed to check system availability and continued
stability.
3.5.3. Security
The data within the onboard EEPROM, personality array shall be protected by a CRC with a HD>=6
3.5.4. Maintainability
As most aspects of this module are software configurable, little maintenance is likely to be needed,
Tuning is minimized
Specific configuration data may be stored within the Personality EEPROM.
Adjustments are minimal, and likely to be limited to TCXO and RX Helical adjustment. and in the case
of a Power amplifier equipped version Helical Filter tuning.
