Frequency Domain (Custom OFDM)

Menu Path: MeasSetup > Custom OFDM Properties... > Frame Definition tab

Frequency Domain is a subset of the General Frame Parameters parameter group and contains parameters that apply to all symbols within the frame.

Half Subcarrier Shifted shifts the subcarriers by half the subcarrier spacing.

Selected - The demodulator expects the subcarriers to be shifted by half the subcarrier spacing.

Cleared (default) - The demodulator does not expect the subcarriers to be shifted by half the subcarrier spacing.

FFT Size sets the FFT Fast Fourier Transform: A mathematical operation performed on a time-domain signal to yield the individual spectral components that constitute the signal. See Spectrum. size.

Default: 64

Lower Guard Subcarriers specifies the number of lower guard subcarriers in the frame.

Default: 6 subcarriers

Upper Guard Subcarriers specifies the number of upper guard subcarriers in the frame.

Default: 5 subcarriers
