[time-nuts] New NTBW50AA

[Mark Sims]

Geee,  what's so hard to understand?   As I said several times before,  the firmware on these units can only read the temperature sensor to 1 degree increments (there is a 0.25C offset).   The temperature "jumping around" is the temperature crossing the 1 degree C quantization threshold.   Most of the firmwares do a running average of the last 10 readings,  so you can see some intermediate values.  
Also, due to a bug in the temperature sensor chip,  you can see occasional spikes in the temperature readings.  These show up as a step impulse on the leading edge followed a decay over around 10 seconds.  All of these temperature sensor issues have been discussed ad nauseum here before.
