agilent_53131A_53132A_Timebase_us_oven (3)-600

Gaurav Singh made an open source 53132A OCXO Ultra stability time base, that is available on github:

While i was working with my own GPSDO project. i need to have a frequency counter with descent stability so purchased my self a Agilent 53132A which is a 12 digit frequency counter, big brother to 53131A 10 Digit Counter. Both are really nice units.
But they unusable standard Timebase. So optional oven oscillator time base need to purchase. but 53132A and 53131A both unit are no longer available for sale and neither of the Time base upgrades.
