144MHz VHF FM Transceiver Trainer
KL-900B Analog Communication System discloses the secret of the walky-talky based on the 144MHz VHF band. The circuitry of walkytalky is shown as blocks : receiver block, transmitter block, audio mplifier block and microphone amplifier block. Block diagrams are printed clearly on the panel of the module, giving students a comprehensive view of how walky-talky works.
The KL-900C AM / FM / ASK / FSK Transmitter and Receiver System is a comprehensive and self-contained system and is suitable for carrying out AM / ASK and FM / FSK transmission experiments. The complete system contains KL-900C1 and KL-900C2, eight separated modules including:
• AM transmitter & receiver modules • FM transmitter & receiver modules • ASK / AM transmitter & receiver modules • FSK / FM transmitter & receiver modules
Fiber Optic communication is one of the most popular technologies in the modern days due to its high transfer speed and large capacity.
KL-900D uses fiber optic as a transmission media for the whole experiment. Four different methods of data transmission (self-module transmission, module-to-module transmission, PC-to-module transmission and module-to-PC transmission) and various different modulation /demodulation methods (CVSD, ASK, etc.) are introduced in the training system. Users can obtain a clear view of how fiber optic transmission works.
NFC (Near Field Communication) is a type of short-range wireless technologies, with typical distance of 10 cm or less. NFC is compatible with existing passive RFID (13.56 MHz ISO/IEC 18000-3) infrastructures. KL-900E NFC Trainer covers three parts: (1) NFC Principle of Transmission, (2) NFC and Contactless Smart Card and (3) NFC Appliance Integration. We hope to provide a complete learning experimental instrument for NFC that covers from physical to application layer for the novice.
EMC-100 contains two parts. One part is a measurement instrument designed to measure electromagnetic interference (EMI), including conductivity of electromagnetic interference and radiated electromagnetic interference. It provides electromagnetic interference verification on products before inspection. Another part is training modules which allow students to easily implement the experiments and learn the basic concepts of electromagnetic interference and suppression countermeasure. Beginners are able to learn electromagnetic interference theories, measurement and suppression techniques to prepare themselves as being an EMC engineer.
