ah yes, that drop-dead power meter (had forgotten that beauty)
no, for my purposes I can get by with 5½ or 6½ digit dmms,
but a good thought

re the software:
have (very) limited exp with LabVIEW 5.1 and 6.1, the latter being far better for ease of use
(by the ignorant/untutored such as I)

am exploring Matlab as their Control Box should provide all that I would need (??)

what I need to accomplish is not difficult given that it is the control of GPIB instruments,
but the learning curve for this can be quite steep when done w/o prior experience
- the value of LabVIEW seems to be with the virtual instrument drivers which enable instrument setup and control through the GUI w/o ever having to program anything;
Matlab I think requires use of the GIPB command instructions

I had an offer of assistance from a metrology guy, but it vanished when he understood that I had a budget of zero for $1500 PCI DAQ cards

my simplistic appraisal of the 'need' is this:
- no control required, though with LabVIEW PID controllers and such are quite simple to setup - just REAL difficult to 'tune', and the requisite flow control hardware is unknown to me
- just data acquisition; hit 'START' and everything starts recording at the frequency/interval defined
. several parameters need a 'live' display as they are the 'controlled variables', and need to be viewed as a graph

this the kind of 'system control' you had in mind ?
