ANALOG COMMUNICATIONS TRAINING SYSTEM
MODEL 8080
The Lab-Volt Analog Communications Training System
is the first in a comprehensive series of advanced systems-level programs that use the latest communications
technologies to teach analog communications theories
and practices in a variety of training environments.
The system consists of six instructional modules supported by six instrumentation modules, and courseware
that provides hands-on exercises in the generation,
transmission, and reception of amplitude, double sideband, single sideband, frequency, and phase-modulated signals [Amplitude Modulation (AM), Double-Sided
Modulation (DSB), Single-Sideband Modulation (SSB),
Frequency Modulation (FM) and Pulse Modulation (PM)].
A door on the top of each instructional module provides
access to circuit boards, test points, and fault-insertion
switches.
Model 8080-A0, an alternate system, includes the
LVDAM-COM software and interface, Model 9407,
which replaces three of the six instrumentation modules
(Frequency Counter, True RMS Voltmeter/Power Meter,
and Spectrum Analyzer) of the standard system and an
oscilloscope, with a set of computer-based instruments.
See page 24 for additional information.

FEATURES
• System applications cover the areas of generation,
transmission, and reception of amplitude, double sideband, single sideband, frequency, and phase-modulated
signals.
• Instructor-enabled fault switches enhance and develop
students’ troubleshooting skills.
• System design allows performance of voltage and signal
measurements, alignment, calibration, and signal tracing.
• Coaxial cables eliminate radiation and noise interference.
• System can be wireless with the use of antennas in place
of coaxial cable.
• Noise can be introduced to simulate atmospheric disturbances, and to provide realistic signal-to-noise evaluation.
• A Power Supply/Dual Audio Amplifier is the base of the
complete system.
