So no surprise there. It must be ballasted, like almost all RF power

Yes, do that. You don't really need the curve tracer for that. Just a
single point measurement, done with a power supply, an amperemeter, a
voltmeter (or a multimeter with both functions), and a small selection
of resistors, will do.
