Hello all,

   1st easy question, between all of the 10811- 80160 -80120 -80111 what is the better model ?
10811-60109 Seems to be a great but non existent thing  < 2.5 x 10-12
10811-60111 No time stability specs   < 1.0 x  10-11 1s
10811-60120 The best characterized  < 5.0 x 10-12  1s  << My guess being this is the better available one ?
10811-60158 Found 1 somewhere, no clue where it goes ...  < 9.8 x 10-13
10811-60160 cheaper 60111 ?
10811-60260 improved aging 10811-60160

They all have different phase noise too, some go down to -103@1Hz/162dBc@10kHz

These are rather confusing....  Wondering which one is the original Option 012 in a 53132 and option 010 53131/132/181...

I guess the HP86##X option 001 is using the HP1813-1304(MC6811X4), which is a rebranded 10811-??  from that list.
