Hi Bert - one way to share large files for free is dropbox.com. The free
account is good for 2 GB. Drag and drop for very easy use, it creates a link to
put in your email to get to the file.
As an owner of a (very nice) Z3805A, I would also like to know more about it's
MTI 5 MHz. oscillator, MTI 260-0624-C
MTI's web site is http://www.mti-milliren.com/catalog.html
MTI 260 - http://www.mti-milliren.com/ocxo_260_ocxo.html

I have not seen any plots on the 260 or E1938A on this site, I have only
been on for a year, how ever I have a "few" 10811s" that Corby Dawson ran for
me all below 1 E-12 one as low as 4 E -13 in the 1 to 100 sec. range. My
problem is that Corby's file size is 900K and I have not found a way to
compress otherwise I would share some of the results.
