Description

Carrier Power

Carrier Freq Offset

Carrier Frequency Offset

Mod Index or Freq Deviation

Modulation depth for AM modulation or Fre-

quency deviation for FM modulation

+Peak

Positive peak (maximum)

-Peak

Negative peak (minimum)

Peak/2

Average of positive and negative peaks

RMS

Root Mean Square value

Mod Freq

Modulation frequency

SINAD

Signal-to-noise and distortion
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 spec-

trum span. The DC offset is removed before the

calculation.

THD

Total harmonic distortion
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 spec-

trum span. The DC offset is removed before the

calculation.
