[time-nuts] TBolt question: Osc Age Alarm

[WarrenS]

The Tbolt Limit alarm indicates that the Dac is near it ALLOWED limit.
It will come on early if the min or max dac voltage has been reset to a low 
value, such as min Dac voltage = 0.

Hi

I would agree that it's a limit alarm - except, I've seen the alarm come on
when the DAC was at 0.5V.

The OSC AGE ALARM is a minor alarm that indicates the oscillator control
voltage is near its minimum or maximum value. The manual indicates that if
this happens the oscillator will probably be at its control limit within two
years.  The tbolt firmware does not attempt to estimate  the oscillator
aging rate.  The alarm is based only upon the control voltage value.
Once the oscillator control voltage reaches its limit,  the major OSC: BAD
alarm is signaled.
