The power and frequency ranges below define the efficiency of the harmonic filtering implemented in the RF
Explorer Signal Generator Combo model.
These values are measured at reference output signal at -20dBm, measuring all harmonics order #2 - #10, as
this is representative of worst-case scenario.

Usually harmonics have better filtering at higher power levels up to +10dBm, and about the same response
on lower power levels. Higher signal levels beyond +10dBm may increase harmonics due to saturation of
internal power amplifiers.
