[time-nuts] Generator MTI 260 for GPSDO

2013-10-29 Thread Nick Medina
I have bought such generator http://www.ebay.com/itm/MTI-260-261-SC-CUT-5mhz-ultra-high-stability-high-reliability-ocxo-oscillator-/291005366483?pt=US_Radio_Comm_Oscillatorshash=item43c14580d3 I want to use it for GPSDO. Does anybody know typical circuit of using this generator MTI260? Thank you

Nick, While I don't know how to build the GPSDO circuit I do have some recent experience with MTI OCXO's. The model number on your OCXO (based on the eBay photo) is 260-0624-C. This is not one of the base model numbers and, therefore, indicates it is a customized version. So to use it

I think you would have a decent chance of getting any 240 to work. While we did have our own configuration, I think it was just to allow full range tuning across the subset of tuning voltages we could reach with our dac, which is really reaching, but maybe .5 to 4.5V. As long as the 240

Sorry in advance guys, I could not resist doing a short comparison between our LC_XO module and this new Selig/RF-Suisse 1x1 module. Please excuse this blatantly biased comparison: The Selig module is slightly larger, and consumes about the same amount of power as the LC_XO (TCXO

Hello, I was talking to a distributor here in San Jose and they told me the Trimble Mini-T is no longer available. Does anyone on this list know why Trimble decided to stop making it? The distributor doesn't know. Thanks, John Westmoreland ___

Bob, Yes - well, it is a little dated - so I would think the chance for a competitive edge would have expired. Maybe not for models C and D but I would certainly think so for Models A B. There must be some sort of technical statute of limitations, correct? ;) Regards, John Westmoreland
