| FTS Subsystem Key Charateristics |
- Generation and distribution of very stable reference frequencies,
time codes, and timing pulses for other subsystems
- Provides measurement for clock synchronization and syntonization
traceable to National Institute of Standards and Technology (NIST), to
Universal Time Coordinated(UTC).
- Provides simulated time
- Provides interface for centralized monitor and control
- Provides calibration tones for very Long Baseline Interferometry
(VLBI)
- Continuous operation Subsystem availability of 0.99997
- Fractional frequency stability better that 1x10-15 between 1000
and 10,000 seconds.
- Timing pulses < 2-ns jitter (1
 )
- User-selectable distribution of UTC or simulated time epoch
- Knowledge of absolute time synchronization of 50 ns (1)
and frequency offset of ±3 parts in 10-13
relative to NIST-UTC.
