Communication Systems Laboratory-ELEN 415

Communication Systems Laboratory-ELEN 415


Location: P. B. S. Pinchback Engineering Building-Rm. 438

Purpose of the Lab: This laboratory is used to reinforce fundamental concepts in analog communications through hands-on hardware lab experiments using Lab-Volt and Aligent equipment. This lab is used in conjunction with the Communication Engineering I (ELEN 409) course. The experiments and lab assignments cover the fundamentals of signal modulation and demodulation techniques and various subsystems of communication systems.

Equipment/Apparatus: The following equipment setups are available for lab use.

Lab-Volt equipment:

Lab-Volt Dual Audio Amplifier (Model 9401), Lab-Volt Frequency Counter (Model 9403),

Dual Function Generator (Model 9402), True RMS Voltmeter/Power Meter (Model 9404), AM/DSB/SSB Generator (Model 9410), AM/DSB Receiver (Model 9411), SSB Receiver (Model 9412), Direct FM Multiplex Generator (Model 9513), Indirect FM/PM Generator (Model 9414), FM/PM Receiver (Model 9515), and Power Supply

  • Aligent Spectrum Analyzer Model 8591E (9KHz-1.8 GHz) or Lab-Volt Spectrum Analyzer (Model 9405)
  • Aligent 54622A Megazoom 100 MHz Oscilloscope (200 MSa/s)
  • HP 4100N LaserJet printer


In addition to the above apparatus, this lab is equipped with the following equipment: Dell Optiplex GX150 computers, BK Precision 4070A 21.5 MHz Multifunction Arbitrary Waveform Generators, Agilent 34401A 6 ½ Multimeters, Dell Optiplex GX270 computers, Gateway 2000 monitors with a Gateway GP7-600 HD and a Dell Dimension 4100 HD. The Dell Optiplex GX150 computers include the following MATLAB toolboxes and blocksets for MATLAB Version 7.3.0.267 (R2006b): a Communications Toolbox, a Communications Blockset, a Signal Processing Toolbox, a Signal Processing Blockset, a Control Systems Toolbox, an Image Processing Toolbox, a Neural Network Toolbox, a Fixed-Point Toolbox, a Symbolic Math Toolbox, an Optimization Toolbox, and a Wavelet Toolbox. These computers also have additional programs such as the SPECCTRA ShapeBased Automation Software Version 15.1 Startup, Stateflow, Simulink Control Design, and the PSPICE Version 10.1 (i.e., Cadence PSD 15.1) software. This lab is also equipped with an Agilent 54642A Megazoom 500 MHz 2 Ga/s Oscilloscope, an Analogue Unit 33-10, a Digital Unit 33-120, a Feedback Power Supply, and an Agilent 34401A Digital Multimeter.
