Hi Francis,
 
Thank You for the advise, do you remember which capacitor to disconnect.
 
Best regards,

Sal,

    It's also a relatively simple mod to rearrange things in the 59309A  to accept the 1 pps input from a GPSDO.  I no longer have my unit for the exact reference, but it simply involved lifting one side of a capacitor and connecting it to the external DC BNC on the back.  Feed in the 1 pps, set the clock, and you're good.

in addition, they are? readily adaptible to 10 MHz input using the
external power bnc and a cmos decimal counter chip.
