NI ELVIS Telecommunication Education Resource Page

The NI ELVIS platform currently has two different plug-in modules that enable a hands-on approach to teaching introductory telecommunications concepts: the Emona DATEx for baseband analog/digital communications and the Emona FOTEx for fiber-optic communications.

With the Emona DATEx, students can build live communications systems in hardware by wiring together circuit blocks using patch cables. The DATEx includes over 20 circuit blocks for fundamental communications operations and connectivity to NI ELVIS I/O.

With the Emona FOTEx, students can build live communications systems in hardware and use fiber-optic connections to transmit the signals over fibers to examine and understand the properties of fiber-optic communication. The FOTEx also includes over 20 circuit blocks for fundamental communications operations and connectivity to NI ELVIS I/O.

After building a circuit with either module, students can apply the signal generation and measurement capability of NI LabVIEW and NI ELVIS platform to explore the system. The DATEx and FOTEx kits both include pre-written labs that engage students with a hands-on experience to teach communications concepts. The DATEx covers analog and digital communications concepts such as AM, FM, DSB, SSB, PAM, PCM, PWM, speech, SNR, equation modeling, sampling, TDM, PCM, ASK, FSK, BPSK, QPSK, QAM, DSSS, noise generation and more. The FOTEx covers PCM, sampling, TDMA, line coding and bit-clock regeneration, fiber optic transmission, optical signal filtering, splitting and combining, fiber optic-bidirectional communication, WDM, and more.

DATEx stands for “Digital Analog Telecommunications EXperimenter” and FOTEx stands for “Fiber Optic Telecommunications EXperimenter”. Both are designed and manufactured by EMONA Instruments in Sydney, Australia.

Curriculum  

Emona DATEx
	Using the Emona DATEx to model equations
		Learn how to model equations by using the Emona DATEx to implement two straightforward equations.  View Now.
	Amplitude Modulation (AM)
		In this experiment you will use the Emona DATEx to generate a real AM signal by implementing its mathematical model. View Now.
	Binary Phase Shift Keying (BPSK)
		In this experiment you will use the Emona DATEx to generate a BPSK signal using the Multiplier module to implement its mathematical model. You will then recover the data using another Multiplier module and observe its distortion, finally you will use a comparator to restore the data. View Now.
	Under-sampling in Software Defined Radio
		In this experiment you will use the Emona DATEx to set up a bandwidth limited signal and then use it to explore the difference in the spectral composition of a sampled signal produced using a variety of sampling frequencies above and below the Nyquist Sample Rate.  View Now.
Emona FOTEx
	PCM Encoding
		For this experiment you'll use the PCM Encoder module on the Emona FOTEx to convert the following to PCM: a fixed DC voltage, a variable DC voltage and a continuously changing signal.  In the process, you'll verify the operation of PCM encoding. View Now.
	Fiber optic bi-directional communication
		For this experiment you'll use the Emona FOTEx to set up a uni-directional communication system over a fiber optic channel. Once you've established that the set-up is working, you'll modify it to implement a full fiber optic bi-directional communications system and investigate its operation. View Now.

The Emona DATEx and the Emona FOTEx include a complete Student Lab Manual. The experiments are self-contained, and include background information, an overview of the experiment, and a step-by-step procedure, and ready-to-assign questions for the student to answer as part of the Lab exercise.

Webcasts 

This webcast introduces the Emona DATEx telecommunications trainer, an add-on module for NI ELVIS, NI ELVIS II and NI ELVIS II+ that offers a hands-on, block diagram approach to teaching introductory telecommunications concepts. The webcast features a step-by-step walk-through of a typical experiment, showing how students can quickly build  base-band communications systems by wiring together circuit blocks from the DATEx with patch cables. View Now.

The Emona FOTEx extends the National Instruments Educational Laboratory Virtual Instrumentation Suite (NI ELVIS), NI ELVIS II, and NI ELVIS II+ with hardware and lab exercises to teach concepts related to fiber optic technology for digital communications. Developed by Emona Instruments, the Emona FOTEx employs an effective, modular, and hands-on approach in which students can rapidly build baseband communications circuits with fiber optic links by working with fiber- and wire-based patch cables. Watch this webcast to learn ways you can use the FOTEx with NI ELVIS for an effective, hands-on approach to teaching introductory fiber-optic-based communications. View Now.
