TIMS is laboratory teaching hardware forcourses in - Wireless, Digital Communications,Fiber Optics and Signals & Systems.
n TIMS, Telecommunications Instructional Modeling System, is laboratoryteaching equipment for EE and EET students in wireless, telecommunicationsand signal processing courses.
TIMS has the distinction of being the only telecommunications lab equipmentthat can implement practically any form of modulation or coding - keepingpace with the rapid development of telecommunications theory.
• OPEN ENDED & EXPANDABLE ARCHITECTUREAs TIMS is an open-ended architecture system, TIMS can implement from themost basic communications systems theory, through to the very latest incoding and modulation.
• SELF CONTAINEDTIMS is self contained requiring only an additional oscilloscope forwaveform display and PC for detailed spectrum display and measurements.
• PC-INTERFACE - INSTRUMENTATION, LabVIEW™ & MATLAB™As well, TIMS can interface to a PC providing data acquisition and spectrumanalysis facilities and a range of supporting math applications.
• STUDENT PROJECTSTIMS is the ideal system to allow students to conveniently develop, built andanalyse the performance of their thesis projects.
ACTUAL TIMS WAVEFORMS
TIMS is a ‘hands-on’ lab system where engineeringstudents learn mathematics “by-doing”
through practical experience.
Complete TIMS-301C Standard Kit
STUDENTS BUILD IT USING TIMS MODULES
REPRESENT IT AS A BLOCK DIAGRAM
QPSK
xp (t).cos ωc t + xq (t).sin ωc t = QPSK
where xp (t) and xq (t) are alternate elements of a digital sequence.
In telecommunications, Math andTheory is always expressed in theuniversal language of BLOCK DIAGRAMS.
Telecommunications engineers makesense of math and theory throughBLOCK DIAGRAMS.
Students patch the BLOCK DIAGRAMSbased on communications theory - thenview and measure real time signals.
Telecommunications text books are a sourceof equations and theories. This is the startingpoint for a TIMS experiment.
STUDENTS PATCH OUTPUTS TO INPUTS TO BUILD THEMODULATION SCHEME and HAND ADJUST EACHPARAMETER: gain, phase, frequency, coupling, alignment,synchronization....
TIMS is a True Hardware Math Modeling System. . . . . more than just a “trainer”
TutorTIMS-R2 is a TIMS telecommunications experimentssimulator which looks just like the TIMS lab equipment.All front panel controls mimic the TIMS lab hardware system,with true point-and-click technology. No programming or syntax entry is required. So students canstart patching telecommunications experiments in minutes. Three versions of TutorTIMS are available:
• TutorTIMS-Advanced-R2 with Signals & Systems Unlimited User, 25-User, 15-User, 5-User, 1-User, and Annual 30-User license.
• TutorTIMS-Basic-R2 with Signals & Systems Unlimited User,• TutorTIMS-Basic-R2 Unlimited User
TutorTIMS-R2 is ideal for helping students prepare at homebefore attending hands-on labs at college.
net*TIMS hardwareexperiment in the lab. Each student PC on the
LAN has a unique studentexperiment session.
Each student on theINTERNET has a unique
student experiment session.
The TIMS-301 System is a true, real-time, hardwaremathematical modeling system.
TIMS can be continuously and inexpensively expanded toimplement the very latest developments in telecommunicationsand signal theory.
The TIMS System is made up of different plug-in and fixedmodules. Each TIMS plug-in module realises a fundamentalcommunications/signals building block and these blocks areused and re-used in different experiments.
No single TIMS module is a complete experiment.
TIMS modules include a wide variety of analog, digital andDSP building block functions.
Students quickly become familiar with the TIMS front panelconventions and are able to easily incorporate differentmodules into their experiments.
