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. Bert Kehren Miami In a message dated 6/11/2010 9:52:55 A.M.
