WLAN Context Type

The WLAN context extension is a solution for configuring any WLAN WLAN - Wireless Local Area Network: A system that includes the distribution system (DS), access points (APs), and portal entities. It is also the logical location of distribution and integration service functions of an extended service set (ESS). A WLAN system contains one or more APs and zero or more portals in addition to the DS.-compatible measurement type—including Spectral Emissions Mask (SEM)—using an IEEE Institute of Electrical and Electronics Engineers. A US-based membership organisation that includes engineers, scientists, and students in electronics and related fields. The IEEE developed the 802 series wired and wireless LAN standards. Visit the IEEE at http://www.ieee.org standard configuration. Since this measurement has WLAN characteristics, you can create a single IEEE standard configuration and apply to this measurement. The applicable presets will be used to configure the measurement's signal-related parameters. For SEM measurements, the WLAN context will configure your carriers, power reference, offsets, and limits for you.

Standard - The Standard drop-down list specifies the demodulator radio standard format. These standards conform to the IEEE 802.11 Specification.

Signal Acquisition Mode - In order to handle cases where hardware limitations might prevent the WLAN context's presets from achieving a successful data acquisition, the Signal Acquisition Mode defines how VSA performs its data acquisition for the given preset, or responds to IF bandwidth limitations in the hardware.

Auto - When auto is selected, the VSA will automatically determine if the preset's bandwidth requirement will be met by the current hardware. If the hardware cannot support the required bandwidth for the given preset, a multi-band sequenced acquisition is configured automatically. In this mode, regions, such as offsets in SEM, may be disabled in order to achieve a successful acquisition with valid data.
Single Acquisition (Disable regions exceeding max span) - When this mode is selected, the VSA will configure the preset to acquire data using a single acquisition, and any regions, such as offsets in SEM, may be disabled in order to achieve a bandwidth the hardware can support.
Multi-band Sequential Acquisition - When this mode is selected, the VSA forces a multi-band sequenced acquisition to capture the data for this preset. This occurs regardless of whether the preset falls within the maximum IF bandwidth of the hardware. In this mode, regions, such as offsets in SEM, may be disabled in order to achieve a successful acquisition with valid data.

Choices: Auto, Single Acquisition (Disable regions exceeding max span), Multi-band Sequential Acquisition
