Hi All. I have a related question.. From a maximizing the life span of the BVA perspective if one only wants to use it once a year or so and can wait for a month or so for it to stabilize, does it make more sense to mostly leave it powered down or is leaving it running all the time a better plan ? I realize this type of question may not have an definitive answer but I am curious about the views of others.
I have a couple of other OCXO's that I leave running all the time and have never quite gotten around to putting together a guaranteed to never go down DC supply for my BVA. My read on the voltage specs for my BVA discouraged me from simply powering it from my 24 volt DC battery bank that is float charged at a somewhat higher voltage when AC power is available. Given the typical price of a BVA, I don't have a spare BVA in my time lab and would like to maximize its life. Over the years several other pieces of gear have failed but I have spares for them (: Thanks in advance for any comments.
