Label Description
SINAD Signal-to-noise-and-distortion
(Calculated only if AF Spectrum is displayed)
Measures the ratio of the total power to the power of noise and harmonic distortions.
The noise and harmonic power is calculated inside the AF spectrum span. The DC
offset is removed before the calculation.

The ratio of the harmonics to the fundamental and harmonics. All harmonics inside
the AF spectrum span are considered up to the tenth harmonic.

In addition, the following general information for the input signal is provided:
●
Carrier Power: the power of the carrier without modulation
●
Carrier Offset: the deviation of the calculated carrier frequency to the ideal carrier
frequency
●
Modulation Depth (AM or RF Time Domain only): the difference in amplitude the
carrier signal is modulated with
