Re: 53131A, 53132A, 53181A Extra Channel option upgrade/downgrade


 

Hi again,

I've updated my 53132A to version 4613 software to see if that would give me a divide by 512 count, but that had no effect. I've also?changed the?10MHz reference otbcode0,1 pins to see if you need to have a high stab source to get the divide by 512 and I still only get divide by 128?as has been stated by others in this thread who have tried the mod.


So I suspect there are other bytes that need changing in the eeprom to enable the divide by 512, not just those currently identified in this thread. At the moment those 3 bytes can have any value and I still only get divide by 128 with ch3code0 tied to gnd. ch3code1 has no effect.


It's either there are other bytes involved, there is something more required on the??main board, or when I initially did this change and corrupted my eeprom I lost some critical data.


So if anyone who has either done this mod and it worked or has an eeprom image they can upload to the files section or send to me?I would appreciate it, then at least I'll know if I lost some data or if there are other bytes involved.


Thanks

Greg
