Available Features (802.11n/ac/ax/be)
The following features are available with OFDM Orthogonal Frequency Division Multiplexing: OFDM employs multiple overlapping radio frequency carriers, each operating at a carefully chosen frequency that is Orthogonal to the others, to produce a transmission scheme that supports higher bit rates due to parallel channel operation. OFDM is an alternative tranmission scheme to DSSS and FHSS. Demodulation:
- Standard 802.11n HT high throughput OFDM, Standard 802.11ac, Standard 802.11ax, Standard 802.11be

- Averaging is applicable
only in the following circumstances:
- Multi-burst averaging is available for OFDM RMS Error Vector Spectrum, Channel Frequency Response, and CPhase Noise Spectrum trace data.
- The
following averaging types are available for the numeric error summary
data and for the pre-demodulated spectrum trace data:
