9.4.1 Signal Analysis
If you need more information about the signal wave shape and the spectrum of the measured
signal you can use this menu. It is only for information purpose and has no importance for
analyzing the test object.
9.4.1.1 Spectrum
This tab sheet will show you the spectrum of the measured signals. The amplitudes are related to
the amplitude of the first harmonic in percent %.
The first 15 harmonics are shown.
In
If this Tab Sheet is selected you can see the spectrum of the current through
the nominal standard capacitor
Ix
If this Tab Sheet is selected you can see the spectrum of the current through the
test object
Un
The Spectrum of the integrated In(Ref) signal will be shown. This corresponds
to the applied test voltage.
9.4.1.2 Scope
With this tab sheet you will get an impression of the real data, which is recorded by the Analogue
Digital Converter (ADC). The amplitude of the signal corresponds with the degree of modulation
