Range testing really is only good for antennas to determine patterns
out of near-fields. "Range testing" the rest of the gear is too
difficult due to to many variables. If you really want to properly
test the gear, you really need to put them back with calibrated
lines and a calibrated variable attenuator between them... Much like
a HP 394A or better.

Intersil has a white-paper on how to determine RX sensitivity that
can be seen at:

This is a pretty standard lab setup that one would use for pretty
much any RX sensitivity measurment.
