I want to measure specs on a preamp. I have a computer based analytical system so I can measure output, distortion, frequency response, etc.
But, what about an output load. Shouldn't the device be under some load while under test? Perhaps it should be connected to an amp with is connected to a dummy load.

Standard solid state preamp loading would be 10k in parallel with 1nF.
A tube preamp load should be higher, perhaps 100k.
