Hello all, first, thanks for all the answers!
Maybe let me ask the more fundamental question: Completely independent of use scenarios and so on: Assume device A uses standard reference tied to ultra-stable zero-drift magic 10 MHz refclock. Device B uses TXCO option. Is there any measurement type with any strange setup that you could imagine where B outperforms A just because the combo "standard XO + refclock" is inferior in any respect compared to "TXCO". (Lab/shop equipment, no portability needed.) I mean - not necessarily for this particular Agilent 53230A but for anything of this type and class. @Bill: thanks - exactly the type of advice/opinion I was hoping to get. @Paul Swed: > Unfortunately in the first round of the thread you did not say what you are > actually doing with the system and whats important to you. Measuring time and frequency? Maybe there are some unknown issues that I am not aware of but what I would like to know is whether for any usual measurement made with a timer/freq counter the choice of XO+refclock could be inferior to TXCO. If there are significantly different scenarios in your mind - it would be nice to let me know for what type of measurement you think that the one is better and for what not. Anything except portability issues? > The last answers actually the best considering the base system initial > investment. Well, once a year I buy something more expensive... However, while 2500 EUR seems reasonable for the counter, additional 1000 EUR seems a bit much for the OCXO option. @Joe > You will have to look at the stability measurements of the OCXO versus the > GPSDO to choose that one. OK, do you have an educated guess about the outcome of that? Because acutally doing this comparison exceeds my scope ATM. @Greg > My opinion is that first you need to tell more about how you > are going to use this counter.

I don't know the code right now. - Wolfgang, DL1SKY _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
