Hi Peter, Very interesting. Myself and others have been talkning and writing about doing something like this for an embarassing long time. Is this not pretty much the setup that HP was refering to in the paper and patent that Magnus dug out some weeks ago. Wonder how the Z3816A would like a

Wonder how the Z3816A would like a modified VP inside... Hmmm... a closed loop system, what are really the timeconstants relevant, to make sure it is stable? That is where I am going. The UT+ oncore inside the Z3816A is a simple crystal and easy to feed with the 3325A. I currently have an

[time-nuts] Austron 1210D Manual Update

2007-03-08 Thread Had
Hey gang, For all you Austron Crystal Clock nuts out there that downloaded the manual that Rob provided (Thank You) I have scanned all 37 fold out drawings as full size, 11x17 (B size), scanned at 300dpi, monochrome images, using Acrobat Pro 7.05. They print out pretty nicely for me on a

Thanks, Had! By the way, I'm doing a stability measurement of my 1210D right now, and it isn't bad at all -- it's in the 13s from tau 0.4 seconds out to a little beyond 1000 seconds. It bottoms out at 4.5x10e-13 at 100 seconds (and for all I know right now, that floor may be that of the

No problem John, I've only had this 1210D since yesterday and have found that everything works except for the batteries of course. I have not had any time to do any real work with it. I have been watching it on and off this afternoon running into a SR620 with a external Cb standard and the
