Hello Nuts, I have an HP 58503A with option H14, the Even Second Output (which doesn't start operation unitil the unit achieves GPS lock), and would be interested in getting it back to 1pps. I have compared the unit to one with 1pps and can see no difference. There seems to be no jumpers that are inserted or removed, and the DIP switches are in the same positions (BTW, anyone know what they do?). Have not tried reverse engineering the schematic or started probing yet. Perhaps it is a memory location in eeprom that is access through some kind of diagnostic function?
Any help would be most appreciated. Thanks in advance. Regards, Skip Withrow _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
