36 to 63V P-P into 50 ohms ain't easy ;-)

True. Most systems will extrapolate out to IP3 pretty well, so take a
series of data points at lower power levels.

Another poster has the same opinion, too

then, back to original question:

It seems to be some problem to build equipment to measure over
+35...40dBm IP3 (at receiver input), do you know how it could be made,
or is it some references which might work?

7025 and 7050kHz tone frequencies would do
