WLAN 802.11a/b/g/j/p/n/ac/af/ah/ax Measurement Application

The WLAN measurement application transforms the X-Series signal analyzers into IEEE 802.11 standard-based WLAN transmitter testers by adding fast, one-button RF conformance measurements that will help you design, evaluate, and manufacture your WLAN transmitter.

The software’s capabilities are further enhanced because it is closely aligned with the IEEE standards— including 802.11a/b/g/j/p/n/ac/af/ah/ax—allowing you to stay on the leading edge of design and manufacturing challenges.

X-Series measurement applications

X-Series measurement applications increase the capability and functionality of Keysight Technologies, Inc. signal analyzers to speed time to insight.

They provide essential measurements for specific tasks in general-purpose, cellular communications, wireless connectivity and digital video applications, covering established standards and modulation types.

Applications are supported across X-Series analyzers, with the only difference being the level of performance achieved by the hardware you select.

Real-time spectrum analysis for WLAN 802.11

Adding real-time spectrum analysis to a PXA or MXA signal analyzer addresses the measurement challenges associated with dynamic RF signals such as bursted packet transmissions of WLAN, and to identify interference caused by various signals in the ISM (2.4 or 5 GHz) bands.

  • Accurately observe power changes for an 802.11 signal within a 160-MHz real-time bandwidth
  • Capture random interfering signals with durations as short as 3.57 μs in ISM bands for WLAN signals
  • Perform fast, wideband measurements without compromising EVM, ACPR and other RF measurements
  • Enhance dynamic range with 1-dB variable attenuation (< 3.6 GHz) and fine-adjustable resolution bandwidths

Top Features

By using the X-Series signal analyzers with the WLAN measurement application, you can perform WLAN transmitter measurements in the time, frequency, and modulation domains.

IEEE 802.11a/b/g/j/p signals, 802.11ah 1/2/4/8/16 MHz signals, 802.11n 20 MHz and 40 MHz signals, 802.11af 6/7/8MHz, 802.11ac 20/40/80/160 MHz and 80+80 MHz, as well as 802.11ax 20/40/80/160 MHz and 80+80 MHz signals with all modulation formats, can be measured automatically.

Measurement Details

All of the RF transmitter measurements as defined in the IEEE standard, as well as a wide range of additional measurements and analysis tools, are available with the press of a button. These measurements are fully remote controllable via the IEC/IEEE bus or LAN, using SCPI commands.

Key Specifications

This section contains specifications for the N/W9077A WLAN 802.11 measurement applications. The specifications below are limited to modulation accuracy, channel power, power versus time, and spectrum emission mask measurements.

Definitions

  • Specifications describe the performance of parameters covered by the product warranty.
  • 95th percentile values indicate the breadth of the population (≈2σ) of performance tolerances expected to be met in 95% of cases with a 95% confidence. These values are not covered by the product warranty.
  • Typical values are designated with the abbreviation “typ.” These are performance beyond specification that 80% of the units exhibit with a 95% confidence. These values are not covered by the product warranty.
  • Nominal values are designated with the abbreviation “nom.”
  • These values indicate expected performance, or describe product performance that is useful in the application of the product, but is not covered by the product warranty.

Software Licensing and Configuration

Choose from two license types:

  • Fixed, perpetual license: This allows you to run the application in the X-Series analyzer in which it is initially installed.
  • Transportable, perpetual license: This allows you to run the application in the X-Series analyzer in which it is initially installed, plus it may be transferred from one X-Series analyzer to another.

Hardware Configuration

For optimizing WLAN measurement applications, Keysight recommends a minimum level of X-Series multi-touch instrument hardware functionality at each instrument performance point. Supported instruments include:

  • UXA N9040B
  • PXA N9030B
  • MXA N9020B
  • EXA N9010B
  • CXA N9000B
