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.
