WLAN Modulation Analysis

Gain greater insight into wireless LAN signals with the 89600 VSA software for 802.11a/b/g/n/ac modulation analysis. Option B7R provides spectrum, time and modulation quality measurements for WLAN 802.11a/b/g signals.

Options B7Z and BHJ expand upon the WLAN modulation analysis provided by Option B7R to include 802.11n (Option B7Z) and 802.11ac (Option BHJ).

Option B7Z adds an advanced troubleshooting and evaluation toolset specifically designed to handle the challenge of analyzing an IEEE 802.11n MIMO signal. Option BHJ adds the capability to analyze and troubleshoot the latest 802.11ac signals.

802.11 WLAN standards are among over 75 signal standards and modulation types supported by the 89600 VSA software. The 89600 VSA software is a comprehensive set of tools for demodulation and vector signal analysis.

These tools enable you to explore virtually every facet of a signal and optimize your most advanced designs. As you assess the tradeoffs, the 89600 VSA software helps you see through the complexity.

Technology overview

The IEEE 802.11 WLAN standard includes several extensions: the

IEEE-802.11a/g and the older

HiperLAN2 standards, both of which use burst OFDM signals, with 20 MHz bandwidth.

The IEEE 802.11b/g standard defines a direct sequence spread spectrum (DSSS) signal, with complementary code keying (CCK) modulation, plus an optional packet binary convolution code (PBCC) mode, and an optional shorter preamble.

The 802.11g standard modifies the 802.11b standard, adding the ability to use 802.11a OFDM-formatted signals and an optional 802.11b-compatible DSSS-OFDM mode, plus other modifications.

The IEEE 802.11n standard includes up to 4x4 multiple input, multiple output (MIMO) and 40 MHz channel bandwidth for higher data throughput. High-throughput (Greenfield) mode, non-HT (legacy) mode, and HT mixed mode are three operating modes of 802.11n.

The latest WLAN technology, 802.11ac, achieves very high throughput (VHT) of 1Gb/s with wider channel bandwidths (up to 160 MHz), higher density modulation format (up to 256QAM) and higher order MIMO (up to 8x8).

Analysis and Troubleshooting

Analyze a wide range of WLAN formats

Option B7R analyzes IEEE 802.11a/g/j/p/, HiperLAN2 OFDM formats, as well as IEEE 802.11b DSSS/CCK/ PBCC formats. Optional PBCC modes, short preamble, and CCK preamble of the CCK-OFDM format in IEEE 802.11g are also supported.

Use Option B7Z with the appropriate 2- or 4-channel front end to measure 802.11n MIMO signals with HT-greenfield, HT-mixed, HT-duplicate, and non HT-duplicate 20 and 40 MHz systems.

Option BHJ, which requires Option B7Z, provides 802.11ac modulation analysis. Option BHJ enables you to view and troubleshoot the entire breadth of the 802.11ac modes, providing greater insight and confidence in validating chipsets and devices regardless of the 802.11ac format implemented.

- Support of all signal bandwidths, including 20, 40, 80 and 160 MHz. The 160 MHz bandwidth is supported in both contiguous and non-contiguous modes

- Support of all 802.11ac modulation formats, from BPSK up to 256QAM

- Support for up to 8x8 MIMO

- Support for multi-user MIMO

Easy set-up with complete parameter control

Quickly set up measurements with standard presets, while maintaining the ability to adjust a wide range of signal parameters for troubleshooting. For example, with OFDM systems, you can modify sub-carrier spacing, symbol timing offset, synchronization reference, pilot tracking, equalizer training sequence and more.

For IEEE 802.11b/g signals, you can adjust the clock timing and track phase, and you can select the descramble mode. Automatically detect, despread, descramble and demodulate payload data for IEEE 802.11b/g WLAN-DSSS/CCK/PBCC formats.

For 802.11n/ac, in addition to standard presets and automatic detection, Option B7Z and Option BHJ provide key parameter detection from SIG symbols for fast and easy demodulation.

Evaluate modulation quality down to the bit level

Make EVM measurements at the level needed: overall burst, per symbol, or per each subcarrier in a symbol. Examine the symbols and error table for information on average EVM, peak EVM, demodulated bits, detected header information and more.

For MIMO systems, Option B7Z and Option BHJ provide detected stream bits, a MIMO channel matrix, data burst information, multiple data streams, cross channel results, plus NxN channel matrix values. Automatically determine spatial mapping matrix, subcarrier modulation format, burst length and more.
