This got me to wondering.....:
My primary need for a GPSDO is as a 10MHz house frequency
reference to externally lock my spectrum analyzer up with.
I currently have a Trimble Thunderbolt running and it seems
to be working OK--
Is this a good choice for a 10MHz long-term frequency
reference that does not require hocking my wife's
car to pay for...? (she might notice if I did that...)
I will be a happy camper if I can reliably measure up
to the upper frequency limits of my Tek 497P/494P (21GHz)
to within +/- a few hundred Hz...
Any feedback on this will be most appreciated!!
