To get a valid result, you have to perform a complete measurement with synchroniza-
tion to the end of the measurement before reading out the result. This is only possible
for single sweep mode.

Return values:
<Harmonics> Returns one value for every harmonic.
The first value is the absolute power of the first harmonic. The
unit is variable.
The other values are power levels relative to the first harmonic.
The unit for these is dB.
