The DFS Radar Simulator and Analyzer Test Suite is

a qualified solution for testing the compliance of

commercial equipment operating in the 5 GHz to 6

GHz UNII frequency band in accordance with published

Dynamic Frequency Selection (DFS) requirements.

With an easy to use task orientated user interface, it

is an ideal solution for pre-compliance work on new

commercial devices. The test suite is also used in leading

compliance laboratories around the world and compliant

with USA, European and Japanese published standards

for DFS radar simulation and response analysis.

The system is compliant with USA, European and

Japanese published standards for DFS radar simulation

and response analysis.

The DFS application provides an intuitive, user-friendly

interface with the ability to easily generate and play

compliant radar signature waveforms and then view

and measure how the EUT responds.

DFS testing requirements are of particular importance

for commercial products based on IEEE 802.11a,

ac (WiFi), wireless telephones, unlicensed IEEE

802.16 (WIMAX) applications as well as other

unlicensed devices operating in the UNII band.

The solution comprizes PXI 3000 Series modular

hardware and software to simulate DFS radar

signatures and synchronously analyze the

Equipment Under Test (EUT) responses. PXI 3000

Series modules are supplied integrated into a choice

of PXI chassis with a system controller hosting the

DFS Radar Simulator and Analyzer application software.

Highlights

DFS Radar Simulator - Creating Waveforms

Users can select from a list of regional standards then generate either a specific single radar signature waveform or

a whole test suite of waveforms compliant with that standard. The software arranges work activities by “Project”,

so that all associated files for each project can be archived as a complete folder with the ability to generate the

entire set of waveforms for a given project with the single button push.

Simulation and Analysis - Play and Play/Capture

The application can be used to simply play radar simulation waveforms or play waveforms and analyze responses.

Synchronization between analysis and signal generation ensures accurate measurement of channel move time and

aggregate transmission time etc. Measurement values are displayed together with graphical trace of power vs. time

which can be expanded to observe very narrow transient events in fine detail. Trace results are also available to

output to file for use in documentation.

Stimulus Play Function - Radar Simulation

The play function supports single-shot, repeated, or continuous signal generation. Single-shot operation is ideal

for compliance testing, whereas repeat and continuous operation is provided to help trouble shooting during the

development process. Created waveforms can be identified and replayed as desired, allowing the user to archive

and play back waveforms for activities such as initial verification, re-verification, firmware regression testing, as

well as operational correlation between compliance test houses and their clients.

Play & Capture Function - Integrated Response Analysis

DFS performance analysis could never have been easier. Documentation required by regulatory agencies showing

initial 60 second Channel Availability Checks, with and without radar bursts at the start or end of a Channel

Availability Check, In-Service Monitoring Test power versus time plots, or 30 minute non-occupancy tests are easily
