RTD (Rapid Test Designer)

LTE Protocol Development Application

MX786201A

Introduction

The RTD is a unique environment for creating test scenarios to prove the protocol & behavior of modern

wireless terminals. The Graphical Flow Chart brings many benefits to test creators as well as those executing

the tests and provides fast flexible methods for test iteration, as well as creation and maintenance.

The RTD comes with a suite of multi-RAT (GERAN/UTRAN/LTE) signaling testing libraries for creating and

executing tests on the industry standard MD8480C (GERAN/UTRAN) and MD8430A (LTE) signalling tester

platforms. Together they provide terminal development organizations with the tools needed to support their

development cycle, through integration and onto inter-operability, regression and acceptance. Additionally the

MD8470A provides a system for LTE/CDMA 2000 inter-working development.

Detailed test annotation and test flow

The graphical layout of each test makes it straightforward to visualize the test flow and hence verify and debug

the terminal’s behavior. Tests can be annotated, enabling easy identification of logical and functional blocks so

that they may be re-used by “cutting and pasting” into a new test if required. Test flow is available when

manually investigating failures or when checking for specific conditions.

Fast test creation and execution – tests can be easily created and modified for fast debug and

analysis

Built in pass/fail judgment - preliminary judgment of the tests results using criteria simplifies analysis

Automation of tests – built in intelligent test sequencer and control of device under test means

campaigns can be run unattended

Real time displays – Many parameters are shown during test execution for performance analysis

Proven hardware reliability – existing MD8480C users will know the benefits from the most stable

platform – MD8430A extends that reliability

Virtual Front panel

The RTD allows terminal development teams to

create test scenarios with virtual front panel control.

This provides a fast development, debug and

proving environment without the need to recompile

between iterations. In some cases it is possible to

make changes to the parameterization while tests

are running for examination of performance

Automating the scenarios is also possible, so a

single test can be used to check over a range of

values without any human intervention.

A real time measurement and monitoring application

is available to see the effect of different loading and

scheduling.

Virtual Buttons

Tests can include “soft-buttons” that allow a variety of

functions and features for manual investigation of

terminal performance. E.g. control of power levels

during tests to be modified without re-running the

tests.
