(RADIO TRANSMITTER
AM/SSB/FM/REMOTE
CONTROL)
MCM24/EV is one of the experiment boards that constitute the
Interactive Practical Electronics System I.P.E.S.
It consists of a set of components and circuits for performing
experiments.
The lessons included in this module can be developed in:
- Standard mode: using the switches of the equipment and
consulting the handbook;
- Computerized mode: the interactive software version of
the handbook - SW-D-MCM24/EV - interfaced to the module
via Control Unit SIS3-U/EV, is used. This software inserts circuit
variations and faults automatically enabling the development
of lessons even without teachers assistance.

MCM24/EV
INTRODUCTION
MCM24/EV
TELECOMMUNICATIONS AND TELEMATICS
Experiment board for the study of AM, DSB, SSB (LSB and USB),
FM transmitter and a 4-channel radio control transmitter.
It contains all the pre-assembled electronic components
needed to construct the experiment circuits and divided into
functional blocks which can be interconnected and modified
by means of supplied jumpers and connection cables. The
training program can be extended to cover phase modulation
with experiment board MCM24PM/EV, while experiment board
MCM24/EV and MCM25/EV can be used together to set up a
radio communication link.
TRAINING PROGRAM:
Low frequency processor (low pass filter, level matcher,
tone generator for testing)
Modulation techniques for the following transmissions:
- AM
- DSB (Double Side Band, with balanced modulator)
- SSB (LSB and USB, using quartz filter)
- FM (VCO using varicap diode)
- Of logic states (coder for 4-channel radiocontrol)
Local oscillator
Conversion mixer
RF amplifier
Radio (antenna)/cable transmission
Calibration and measurement of all stages and the
whole module
Troubleshooting
System test and measurement
