Distortion Calculator
The distortion calculator window located to the right of the Amplitude Cal−
culator displays the results of signal analysis algorithms.

• 2nd Harmonic − Displays the level of the second harmonic component
in dB relative to the fundamental signal level.
• 3rd Harmonic − Displays the level of the third harmonic component in
dB relative to the fundamental signal level.
• SINAD − Displays the measured signal noise and distortion (SINAD).
SINAD is defined as the dB ratio of the RMS energy of all signals to the
RMS energy of all signals minus the energy of the fundamental.
• THD − Displays the measured total harmonic distortion up to and
including the highest harmonic component. THD is defined as the ratio
of the RMS sum of the harmonic components to the amplitude of the
fundamental signal. To compute THD as a percentage, multiply the
displayed value by 100.
Resolution Bandwidth Calculator
The resolution bandwidth calculator located to the right of the signal char−
acteristics panel displays the resolution bandwidth based on the frequency
bandwidth and FFT size.
