I used a SIA-3000 in FFT mode for phase noise measurements, they really are not that great for that purpose. Don't think we can get down to -130dBc at 10Hz with accuracy. Then again one could measure loads of TI data on the DTS, and do an FFT on that data. > I had a third DTS unit for parts, and that unit's Vectron was out > of spec > (just shy of 100MHz at full mechanical deflection unfortunately). > Datecode 1994, > so not too bad. >So, if I need parts.... No prob :) I suspect that replacing the simple Vectron 100MHz OCXO with a more modern, lower noise Wenzel etc could improve the instruments performance. That OCXO should be locked to GPS as well of course :) bye, Said ************************************** See what's free at http://www.aol.com. _______________________________________________ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
