where:
For example, enter:
F71<CR>
XLi responds:
F71 PHASE=-5.678E-09 s OFFSET=-1.986E-07 DRIFT= 6.013E-08/DAY DAC=24567<CR><LF>
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
Command Line
To display the status of the fault detectors, enter:
F = ASCII string indicating function F71
<S> = ASCII space character one or more.
<MULT> = multiplier, 4 digits with decimal point.
E = ASCII character E for exponent.
s = ASCII character s for seconds abbreviation
<SIGN> = - for negative or <S> for positive.
<EXP> = 2 digit exponent.
/DAY = ASCII characters, units of Drift Rate
<INT> = integer, 5 digits
<CR> = carriage return.
<LF> = line feed.
