That instrument is obsolete http://www.keysight.com/en/pd-1000000874:epsg:pro-pn-4284A/precision-lcr-meter-20-hz-to-1-mhz but with a basic uncertainly of 0.05%, has much lower uncertainty than many more modern instruments. If you exclude cheap Chinese instruments, where rand() is used to generate the specifications, then there's nothing to touch the 4284A, unless one spends serious amounts of money. A quick Google will find drivers existing to control the 4284A with MATLAB http://forums.ni.com/t5/LabVIEW/hp-4284A-vi-s-for-old-Matlab-version-6-1/td-p/871386 I've not bothered checking, but I doubt there would be with Mathematica.
