[time-nuts] An example of phase noise

Thought this might be interesting. I took a spectrum analyzer shot of my ICS525 Clock-Block synthesizer at 250MHz, and overlaid it with a shot of an RF signal generator (Marconi 2202A) at the same frequency, and using the same reference source. The 2202A is designed for bench use and isn't noted

Hi John: It's my understanding that the lowest jitter comes about when the highest output divisor is used. In case of ties use the lowest VCO divisor. See: http://www.pacificsites.com/~brooke/BTSG.shtml Have Fun, Brooke Clarke -- w/Java http://www.PRC68.com w/o Java
