ok my 83620 is actually a 83640 but someone removed the doubler, so i want to get the unit back to 20GHz , i know that there is a set of correction constants in the 700 range that contain all this info but you need a password to acess those, does anyone know this password ? i can go into the EEPROM and do it manually by changing the info in line 6D70 but if i would prefer the easy way via the password !
