I have one of the Trimble Z3801 look-alikes. It only seems to report
its temperature in half-degree steps, but I left it running for
nearly 27 hours, and saw a couple of 1-second 1 degree spikes during
that time - see attached graph. Could this be the same thing you are
seeing with your real Thunderbolts? There is no 20-second decay that
you are seeing, but then the resolution is very coarse.
The item has several part numbers on its label:
P/N: NTPX26AB-01 D/C: 9828
P/N: 34304-00 -11 Oscillator "T"
and has a small label under the barcode with 1.56 on it - firmware version?
