	Module TPS - 3421 Analog Communication Training System
	Technical Characteristics The trainer is enclosed in a metal case, which has a wide experiment printed circuit board (22 cm x 34 cm). This ensures easy handling and good visibility of the components. The components are located on the board, which has a silkscreen print of the analytical circuit and component drawings. The central part of the experiment board includes all the circuit block drawings and the all the hands-on components and test points. The fixed components are located on the circuit board under a sturdy transparent cover. The system includes a built-in power supply with +12V, +5V, and variable DC voltage outlets. An included external low AC voltage power adapter feeds the system. The system includes: • RC oscillator • Crystal oscillator • Wein bridge oscillator • Pre-amplifier with microphone • AM/FM modulator • RF transmitter and antenna • Tuner RF amplifier and antenna • Mixer and frequency converter • Resonator tuned amplifier with AGC circuit • Band pass filter and slope detector • PLL, VCO, and FM detector • AM detector • Audio amplifier, volume potentiometer, and speaker • SES Lab unit with two-channel scope and function generator, which communicates with a PC to control the function generator and display the scope’s signals, including spectrum analysis • PC software for SES lab unit (optional)	Objectives This course introduces the student to analog AM/FM communication. The course provides comprehensive hands-on experiments in measuring radio signals, oscillators, amplifiers, filters, modulators, demodulators, mixers, and AM/FM communication circuits. Description The system is stand-alone, containing all the necessary electronics components needed for performing the experiments. The system includes the SES Lab unit with two-channel oscilloscope and a function generator, which communicates with a PC to control the function generator and display the scope’s signals, including spectrum analysis. The built-in function generator also can be operated manually, controlled by the embedded micro-controller. A sine or triangular waveform at a constant or sweep frequency is available. Experiments This system enables the student to perform several experiments and covers the following topics: • RC oscillator • Crystal oscillator • Wein bridge oscillator • Pre-amplifier with microphone • AM modulation • FM modulation • RF transmitter • Tuner RF amplifier • Signal mixer • Local oscillator • Frequency converter • Super heterodyne receiver • Tuned (IF) amplifier frequency response • AGC – Automatic Gain Control Amplifier • Resonator tuner amplifier • Band pass filter and slope detector • PLL, VCO, AFC • FM detection • AM detection • Audio amplifier A teacher guide, a student experiment manual accompany the system .
