3.9 SEM Measurement
For WLAN 802.11ac (80 + 80 MHz), the channel span is coupled with the difference between the
center frequencies of the two carriers. When the difference is either less than 80 MHz, or greater than
565 MHz, a “setting conflict” error message is displayed
Chan Span = Carrier Spacing + Chan IntegBW
When the state of Span is Auto, the span value is automatically determined by multi-carrier config-
uration. Otherwise, the span value depends on user input
When the span value is set manually, the state of span is automatically changes to Man
This key is enabled and can be changed only in single carrier. The span state is always Auto in Multi-
carriers
