[time-nuts] HP 3420B calibration assistance

2010-03-18 Thread Dr. Frank Stellmach
Hi Dick, I'm sure, I met the 3420B long time ago..that's a nice unit,.. but I do not have the schematics of the 3420B at hand, also did not find them on the agilent site, only the HP catalogue from 1970. The instrument - as far as I remember - compares the input voltage directly against 0-10
