[time-nuts] Defective High Performance Crystal Oscillators

2014-01-06 Thread Mike M
I'm interested in obtaining your defective high performance crystal oscillators. By defective, I mean 01. no oscillation 02. wrong frequency 03. parastic or spurious oscillations 04. low output 05. distorted output 06. frequency jumps 07. poor or no temperature control 08. unstable frequency

From: Said Jackson Today I would not use a simple (cheap) 1GHz VCO anymore because of the relatively high phase noise, and some if them require up to 20V drive voltage. I would use a Crystal based product such as our ULN-1G 1GHz crystal oscillator. That part may be overkill since

couldn't find any reference to pin 5. http://www.radcomms.net/EFRATOM%20LPRO%20101%20Repair%20Guide.pdf So what does this voltage do in the circuit? Is there a way to measure a similar voltage on a FE-5650A or FE-5680A? Thanks, Mike M ___ time-nuts
