The system includes built-in power supplies, signal sources, function generator, TTL pulse outputs, LED displays, logic switches, IC sockets, open experiment areas, and printed circuit modules for analog and digital electronics education.

Key Features

Portable all-in-one electronics lab
Combines analog circuit training, digital logic experiments, signal generation, power supply, measurement modules, and component testing in one compact training case.

Designed for hands-on circuit learning
Circuit diagrams are printed directly on the experiment panel, allowing students to connect circuits according to the schematic and understand the relationship between theory and real wiring.

Analog and digital circuit coverage
Supports experiments for amplifiers, op-amps, filters, oscillators, rectifier circuits, voltage regulators, logic gates, flip-flops, counters, registers, decoders, 555 timer circuits, and more.

Built-in signal and pulse sources
Includes adjustable DC signal source, function generator, manual pulse generator, and fixed-frequency TTL pulse source for a wide range of circuit experiments.

Durable portable case design
Built in an aluminum alloy carrying case with a fire-resistant experiment panel, making it easy to store, transport, and use in classrooms or training labs.

Expandable experiment platform
Includes IC sockets, component experiment areas, jumper connection points, and modular circuit sections for extended course design and custom experiments.
