F72 – Fault Status
Use function F72 to display the fault status of the clock.
• Clock PLL – Locked or unlocked
• Clock Status – Unlocked or locked plus one of the following reference types:
- GPS Primary receiver
- GPS Secondary receiver
- PTP Primary (when configured as a PTP slave)
- PTP Secondary (when configured as a PTP slave)
- (IRIG-A, IRIG-B, NASA 36 not supported)
• Primary power supply – OK or failed
• Secondary power supply – OK or failed
• Rubidium oscillator (if installed) – OK or fault
