Introduction
LeCroy UWBSpekChek Application
The UWBSpekChek application operates in conjunction with the UWBTracer/Trainer
application to perform a suite of compliance tests defined in the WiMedia Platform Test
Specification. UWBSpekChek automatically executes generation and verification scripts
corresponding to each test case and reports results of each compliance test in detail.
WiMedia Platform Certification Test Scripts
This document describes the procedure for using LeCroy’s UWBSpekChek WiMedia
Platform Certification test suite. This test suite is performed using the UWBTrainer
exerciser operating as the “stimulus” device. Specially designed test scripts are used to
create specific traffic conditions that test proper protocol behavior.
LeCroy’s UWBTracer analyzer is used as the “monitoring” device. It captures the real
response from the DUT / INTD. LeCroy’s UWBTracer is also used to verify compliance
using the included Verification Script Engine post processing application to identify
violations in the Protocol Background Observation tests defined in section 3.2 of the
WiMedia Platform Test Specification. Violation of any of the protocol rules listed in the
background checks is grounds for failing WiMedia certification.
The current release of the UWBTrainer based certification scripts functions as a “TX
only” test system. TX only Test systems are defined as capable of transmitting pre-
defined frames at specified intervals. The system does not acknowledge or process
received packets. In TX only tests, the tester must begin transmitting first and the DUT /
INTD must join the established beacon group.
In all of the test cases for a TX only system, the tester transmits beacons with an
interval of 65538 microseconds to ensure that it is the slowest device in the beacon
group. All test system beacons have a unique EUI-48 and DevAddr and do not have the
movable bit set unless otherwise indicated. By default the WiMedia Certification test
suite will operate on TFC 1.
The UWBTrainer test system transmits all beacons with a compliant BP Length and a
correctly formatted BPOIE. During the WiMedia Platform Certification workshops, each
test is run against the submitted DUT or INTD device.
