[time-nuts] Comparing 10 MHz Oscillators at 10 GHz

2011-01-04 Thread Brucekareen
Luciano Paramithiotti's January 1 post about his 10-to-100 MHz multiplier project reminded me of past musings about using two 10GHz, phase-locked oscillators to compare the 10MHz outputs of my T-bolt and LPRO so I could quickly adjust the latter by observing the mixed 10 GHz signals with a

Bruce- I can speak to the Freq West PLOs. They, like the others, use a sampling phase detector. In theory you could use any subharmonic of the actual L-band VCO frequecy to get the loop to lock. I have used freqs as low as 5MHz. But there are limitations. You must couple the signal direct

Ulrich Strictly for adjusting and comparing two 10 or 5 MHz sources I use the circuit from the Austron 2110 that takes a 5 MHz input and through mixing generates 5.0005 MHz subsequently devided down to 1.0001 MHZ. Mixed with the other input at 1 MHz the resulting difference is 100 Hz which a

List, While comparing oscillators at 10 GHz might work for some it is indeed a daunting challenge at the very least. I would like to propose what may be cheaper and more readily achieved method for Comparing 10 MHz Oscillators by more of us time-nuts. (This is still theoretical) What I propo

Hi The normal term for a gizmo that multiplies and then mixes down is an error multiplier. They were a very common lab item back when I had more hair than I do now.. Various people made them in the 1950's and 1960's. Bob On Jan 10, 2011, at 9:35 PM, Perry Sandeen wrote: > List, > > While co
