Communication and RF Trainers for Engineering Laboratories

Communication trainers let students trace a signal from source to receiver and measure it at every stage, which is the only reliable way to understand modulation. Naugra Export manufactures and exports the complete range from Ambala, India, for engineering colleges, polytechnics, technical universities and TVET institutes worldwide.

Analogue communication

AM transmitter and receiver trainers covering DSB and SSB, FM transmitter and receiver trainers, pulse modulation trainers for PAM, PPM and PWM, sampling and reconstruction trainers, and frequency division multiplexing and demultiplexing trainers. Each carries the full circuit on a single board with test points at every functional block, so waveforms can be observed on an oscilloscope stage by stage.

Digital communication

Data formatting and carrier modulation transmitters, carrier demodulation and data reformatting receivers, ASK, FSK, PSK and QPSK trainers, 16-QAM training systems, PCM generation and demodulation using CODEC chips, delta and adaptive delta modulation trainers, time division multiplexing trainers, and error detection and correction trainers covering parity, Hamming and cyclic codes.

RF, microwave and antenna

Microwave test benches with klystron and Gunn diode sources, waveguide component sets, antenna trainers with rotating masts for radiation pattern plotting, VSWR and SWR meters, transmission line trainers, and satellite communication training systems.

Optical fibre and wireless

Fibre optic communication trainers covering analogue and digital links, numerical aperture and attenuation measurement, and losses in fibre. Wireless trainers covering GSM, Bluetooth, Zigbee, RFID and IoT application modules.

What to check before ordering

Confirm the supply voltage, frequency and plug type for your country, and confirm that an experiment manual and spares list ship with each unit. Ask which test instruments are required in addition — most communication trainers assume a dual-trace oscilloscope and a digital multimeter are already on the bench.
