I have this one:  http://groups.yahoo.com/group/VNWA/

excellent to 500 MHz, quite ok to 1300. 12-term calibration,
Includes "opt. 10", TDR and generates crystal models that work.
Size is 1.7 * 4 * 2.5 inch and lives on USB power if you don't
need all 4 S-params without manual DUT-reversal.

I had of course to add a 10 MHz ref input.

regards, Gerhard
