F72<CR>
The XLi responds:
F72<SP>PLL: <CLK PLL ><SP> CLK: <CLK STATUS><SP><CLK REF:><SP> PWR1:<PWR1 STATUS><SP>
PWR2: <PWR2 STATUS><SP>OSC: <OSC STATUS> <CR><LF>
where:
= ASCII character F
F
= function number
72
= ASCII space character one or more.
<SP>
= Clock Phase Loop Lock status, LOCKED or UNLOCKED
<CLK PLL>
= Clock Status, LOCKED or UNLOCKED to the reference source shown. The
<CLK STATUS>
LOCKED state is based on the F73 Time Threshold value entered by the
operator. F73 Time Threshold sets the threshold in ns above which Time Error
triggers an alarm. When the oscillator's predicted worst-case time error ("F13 -
Time Error" on page 51) exceeds F73 Time Threshold, Time Error enters a fault
state and the CLOCK STATUS becomes UNLOCKED. Otherwise the CLOCK
STATUS is LOCKED.
= Clock reference source GPS PRI, GPS SEC, PTP PRI, PTP SEC, (not
<CLK REF>
supported: IRIG A, IRIG B, NASA 36) AUX REF.
= Primary Power Supply status, OK or FAILED
<PWR1 STATUS>
= Secondary Power Supply status, OK or FAILED
<PWR2 STATUS>
= Rubidium oscillator status, OK or FAILED (if installed)
<OSC STATUS>
= output line terminator
<CR><LF>
For example, enter:
F72<CR>
The XLi responds:
F72 CLOCK PLL
CLOCK STATUS LOCKED GPS PRI
PRIMARY POWER SUPPLY
SECONDARY POWER SUPPLY OK
F73 – Alarm Control / Status
Use function F73 to do the following:
• See the state of an indicator ("Locked/Unlocked" or "OK/Fault")
• Enable or disable the alarm for each indicator
