A test process that sources 2 sinusoidal RF signals at different power levels keeping the frequency constant. The PowerRef signal is sourced and the power is measured by the UUT and saved as the Reference value. Then the power level is changed and the test value is measured on the UUT. The two measured values are compared, the results can be expressed as Delta dB or percent of change.
These two sinusoidal signals are often used when calibrating linearity of a device.
