Hi, Tom --

A paper in the 2010 EFTF described the use of a pair of 11848A boxes from
the 3048A system, which is similar to the E5500 hardware (
http://www.congrex.nl/EFTF_Proceedings/Papers/Session_14_Oscillators_and_Noi
se/14_04_Bale.pdf ).  You could ping those authors if you haven't already.
Also, have you talked with Craig Nelson about his work with the NI
digitizers and T/H amps?  

The 70820A GPIB documentation is part of the overall 71500A reference guide
at http://cp.literature.agilent.com/litweb/pdf/70820-90051.pdf .
