If there is an issue with the 10MHz Input it will show in the
status reference:frequency:external
command.
The front panel Alarm light will be RED and the Oscillator Lock light will be OFF.

When the 10 MHz signal is restored the Alarm light will remain on, the Oscillator lock light will remain out
and the GPS Tracking indicator may go out for ~30 seconds. Once the GPS Tracking indicator is lit the
system will report the kas2 values.
If the 4380A is unable to communicate with the external reference the operator will get an indication of the
error. The front panel Alarm light will be RED and the Oscillator Lock light will be OFF.
