Hello Murray, moving air also affects the DAC and voltage reference, so while your OCXO may perform flawlessly, the EFC voltage can vary. For example capacitors have a thermal voltage on them, Elkos more so than Tantalum, etc all the way down to COG. Thus filter capacitors can affect EFC voltage when you point moving air on them. Then there are all the thermocouples in the solder junctions and cabling, and the other parts.. BTW: the lowest power GPSDO is not the Trimble unit you mentioned - as far as I know it is our FireFly GPSDO which only consumes a meager 1.35W at room temperature, and it also uses an OCXO.

As an aside, it is interesting to note the steady-state power consumption of the various units. The Z3801A is spec'd at 25W, the Z3815A (with hockey-puck oscillator) 35W, and at the other extreme, the Trimble NTGS50AA only 5W! 73, Murray ZL1BPU **************Get fantasy football with free live scoring.
