WLAN Modulation Analysis

Technology overviewThe 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 either

20 or 40 MHz bandwidth. The IEEE

802.11b standard defi nes 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 modifi es 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

modifi cations.

An additional extension, the

IEEE 802.11n HT standard, adds the

ability to measure and decode up to

4x4 multiple input, multiple output

(MIMO) WLAN signals for higher

throughput. This 802.11n standard

further supports mixed MIMO and

legacy transmissions for backward

compatibility.

The next-generation 802.11ac

standard will achieve throughputs

approaching 1 GB/s with wider

bandwidths (up to 160 MHz), higher

density modulation formats (up to

256QAM) and up to 8x8 MIMO.

important Help data topics.

Troubleshoot and analyze 802.11ac signals with 160 MHz bandwidth and 256QAM.

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, including optional PBCC

modes, short preamble, and CCK

preamble of the CCK-OFDM format in

IEEE 802.11g. Use Option B7Z with

the appropriate 2- or 4-channel front

end to measure 802.11n with

HT-greenfi eld, 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, pro-

viding greater insight and confi dence

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 4X4 MIMO

4

Each option lets you adjust many format-specifi c parameters using the

Advanced tab, providing greater insight into your signal under different

conditions, and uncovering anomalies you won’t see any other way.

Here the Advanced tab was used to select a single carrier. The constellation, EVM and symbols/

error table all show results for only the chosen carrier.

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 times, 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 MIMO

systems, Option B7Z or Option BHJ

lets you adjust a wide range of pa-

rameters such as subcarrier spacing,

symbol timing, pilot tracking, tracking

mode, and equalizer training to high-

light potential error sources.

5

Evaluate modulation quality down to the bit levelMake 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 aver-

age EVM, peak EVM and its location,

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 inputs, plus

NxN channel matrix values. Auto-

matically determine spatial mapping

matrix, subcarrier modulation format,

burst length and more. The 89600B MIMO error traces are available for the physical input channels and the logical

streams. Cross channel measurement traces specifi c to MIMO are also available.

View key 802.11ac MIMO parameters such as multiple spectrums, error summary and frequency

response for up to 4 transmit streams simultaneously.

6

Powerful error measure-ments let you look at signal performance in detailError vector spectrum, error vector

time, channel frequency response,

correction, common pilot error per

symbol, and more, are available

for 802.11g formats. Compound

constellation displays let you

determine and display all modulation

formats in the burst. Option B7Z and

Option BHJ add channel, stream, and

cross channel data, providing the most

complete and robust signal and error

characterization in the industry.

The 89600B lets you view up to 20 simultaneous traces, showing data transmitted in the

preambles and headers of the 802.11b/g signal, as well as EVM over frequency and time, IQ errors,

correction spectrum and more. Additional MIMO data is available with Option B7Z.

Option B7Z provides error summary tables, calculated matrix values, and information detected

from the bursts themselves, such as burst structure and HT-SIG info. Scroll bars make accessing

the table data easier.

All 3 displays show the spectrum of this WLAN signal recorded using signal capture. Digital

persistence (lower left) highlights the signal’s amplitude behavior over a short time period. The

spectrogram (right) provides information on frequency behavior over time. The cumulative history

(upper left) provides statistical analysis details on the signal’s amplitude and frequency behavior

over very long times.

Troubleshoot with insightful tools Powerful display modes include

cumulative history, spectrogram,

and digital persistence. Use signal

capture to capture and record tran-

sient events, or share the signal for

collaborative analysis with remote

colleagues. Additional tools, like

overlap processing, let you effectively

“slow down” the apparent measure-

ment for more in-depth analysis.
