Hello everybody !!
I'm getting more and more interested by OCXO's, and GPSDO's in particular.
I read multiple threads about a few known brands like Morion, Oscilloquartz, ISO-Temp, etc, and I'm quite interested to know which ones are in the top 3, stability/phase noise/overall quality-wise !
I'm asking the same question for GPSDO's, and GPS modules too !
I know that not all OCXO's even from the same brand/model are equal, some are better than others (its the same for every production product I guess), but I'm sure this is like wine, some years must be better than others !
And some very knowledgeable and qualified peeps here must know things that aren't in books !
I was interested by purchasing an Oscilloquartz 8663-XS, a Morion MV89A, and a few others cheaper like Bliley, NDK or ISOTEMP to measure them over days/weeks, and see which one is a good performer. Do you have anything to say on those models ? They seem to be highly regarded here ! (the morion seems to have issues !).
I'm soon getting a BG7TBL GPSDO from 2018-01, his distribution amplifier (to connect the GPSDO to my HP 5345A, and Siglent 1032X) and the FA-2 counter (that I will also use with the GPSDO as his reference).
I'm wondering what people think about that FA-2 counter, compared to high-end counters like Agilent, Pendulum's ones, just accuracy wise (once used with a well stabilized GPSDO, with a good signal ofc). I mean, it seems to be pretty nice, it got a huge resolution, and its mostly the external reference that does all the work accuracy wise, right ?
I thought it would be nice to later replace its OCXO with a better one (once I got my hands on a few that were measured during days, prior to that) and power it with a linear supply, instead of a wall-wart. Am I right ?
If it was in a nicer box, with a big brand sticker slapped on it, would people pay much more for it ? (the 1 million dollar question !
)
I'm still pretty new to this, I'm trying to read as much as I can to avoid asking redundant questions, I would greatly appreciate if any veteran time-nut could help me out on those !
Have a nice evening/day !
