Hi, The -60109 usually does have the very good short term stability at short Tau but to actually use it you need to go open loop on the 5065A or 5061A/B.
In closed loop the instrument actually drives the stability and pretty much any 10811 variant will work. HP knew this and recommended going open loop to test stabilities at the shorter Tau.
