High frequency electronic circuit experimental teaching system

Product Introduction
The high-frequency electronic circuit experiment system is meticulously designed based on the syllabus requirements and the needs of experimental teaching. The entire system adopts a modular design approach, with circuits connected by switches (reducing wiring). While each module can be used for independent experiments, they can also be connected to form comprehensive experiments such as wireless voice transceiver systems. The experimental system comes with a built-in high-frequency signal source, frequency counter, and music signal generator. Simply plug in the corresponding experimental templates and complete all experiments without the need for other instruments (besides an oscilloscope).






Features
1. The unit modular design allows users to select modules according to their needs, which can save money and facilitate future upgrades.
2. The system has its own DDS signal generator: it can generate a variety of waveforms such as sine wave, square wave, triangle wave, pulse wave, and arbitrary wave, and has the functions of duty cycle adjustment, frequency sweep, frequency measurement signal frequency and counter, etc.
3. Use TFT color display: can simultaneously display output signal waveform, amplitude, frequency, etc.
4. Multiple waveform types: sine wave, square wave, pulse wave (duty cycle adjustable, pulse width and cycle time accurately adjustable), triangle wave, partial sine wave, CMOS wave, DC level, half wave, full wave, Sinker pulse and other waveforms.
5. Circuit stability and reliability: Various unit circuits have easily consumable components, and the system is designed to be self-maintained and replaceable, which can quickly improve teaching quality.
