[time-nuts] Ultra High Stability Time Base Options for 53132A

i have a 53132A and the the time base from the polish seller as well as 
a time base from gerry sweeny (UK) who uses a trimble 34310-T instead of 
the morion ocxo. both are plug and play and can be easily calibrated.

i have no data, but if i remember correctly, the presence of a high 
stability time base degrades the measured short term stability of any 
DUT, if i use an external reference such as a gpsdo.

if you are interested i could do the following: measure TI between a 
trimble thunderbolt and a trimble 73090 docxo that has been running for 
several weeks

1. without external reference: no high stability time base, morion time 
base, trimble time base
2. the same, but with an external reference (TB).

that will take some time. but i am intersted in this myself, so i could 
give it a try.
