Hi there Jose, Hmurray, how about this one? _http://www.jackson-labs.com/docs/Fury_Flyer.pdf_ (http://www.jackson-labs.com/docs/Fury_Flyer.pdf) It's available in double-oven version (SC-Cut Crystal) and single-oven AT-cut. Software compatible to the HP GPSDO's, but lot's better

Hi Rick, Jose, Hmurray, forgot to mention: the Fury unit only uses about 0.35A at 12V, and runs from 11V to 14V, so it can easily be run from a Pb battery, 4.5W power consumption. 45min warmup time typ. with the double-oven OCXO. Better 100s Allan Deviation stability than the PRS10 SRS

Hi folks, first i would like to announce a new version of PLOTTER which can be downloaded from www.ulrich-bangert.de The new version can classify data and compute new data columns from existing ones using a formula interpreter in that you may input a formula of your own. A lot of mathematic

David, what you are saying, is it not more or less a patronage of my claim? Because the factory selected resistors have surely be selected in a way that tuning the frequency setpoint is possible in the sense a) you have a fine enough tuning resolution to get the job done with your fingers and

Bruce, The manual for the SRS PRS10 states that the combined effects of the buffer gas and the pump lamp spectral profile shift the resonance about 3kHz from the unperturbed natural transition frequency. Ok, this is a word! Perhaps Efratom relied on the reproducibility of lamp
