Using a Standard Setup (802.11n/ac/ax/be/bn)

The VSA can be manually configured to demodulate 802.11n/ac/ax/be/bn signals or automatically configured to demodulate one of the 802.11n/ac/ax/be/bn standard format presets shown in the Standard drop-down list. A standard setup can be used and then the settings fine-tuned if necessary.

802.11n/ac format default parameters and presets

802.11ax format default parameters and presets

802.11be format default parameters and presets

802.11 Non-HT format default parameters and presets

To configure the VSA to a standard format, click MeasSetup > 802.11n/ac/ax/be/bn Demod Properties > Format tab > Preset to Standard and select one of the formats in the dropdown list.

802.11n/ac/ax/be/bn Demodulation must be selected for these Standard Presets to be available.
