Harmonic Power Cal
The Harmonic Power Calibration wizard controls the power calibration of the harmonics measurement. A
power calibration ensures accurate levels at the input of the DUT (source power calibration) and an
accurate power measurement of the harmonic (receiver calibration). The necessary calibration steps are
automatically performed across the entire frequency or power range of the harmonics measurement.
Harmonic power calibration procedure and example
Due to the different frequency ranges of the input and output signals, the harmonic power calibration must
be performed in two steps. For a test setup where the DUT's input signal (fundamental signal) is provided
by analyzer port 1 and where the harmonic is analyzed at port 2, the following test setups are required:
1. Source power calibration of the fundamental signal. A power sensor is connected to port 1. The source
power (red) is calibrated over the selected sweep range. As a preparative for step 2 the analyzer also
calibrates the source in the harmonic frequency range. The correction data for both calibration sweeps is
stored.
