Hi all,
I'm looking for some sort of frequency standard (10 MHz ref.?).
Ebay has rubdium standards for under $100.00 and there are GPS
controlled OXCO standards for $100.00 plus.
My question :
Is a 10-20 year old rubidium standard more accurate (even with aging
drift) that a newer GPS OXCO?
I can't afford a GPS corrected rubidium ( ~$700.00+).
I just want to recalibrate my so-so frequency counters .. to hopefully
within 10 Hz..?
Opinions?
Thanks for reading! :-)
Cheers!
