Electronic oscilloscope DIY teaching and training kit with 1Msps sampling and 12-bit precision

This oscilloscope DIY kit provides a practical, hands-on learning experience for electronics students and hobbyists. It solves the problem of needing an affordable, functional oscilloscope for waveform analysis without investing in expensive commercial equipment. The kit includes pre-soldered components, making assembly straightforward while teaching key concepts. Users need to supply a 9V DC power source (over 200mA, not exceeding 10V) to get started.

Key specifications and features

The kit delivers reliable measurement capabilities suitable for educational and basic diagnostic tasks. Its technical parameters are designed to cover common signal analysis needs.

Sampling and precision

With a real-time sampling rate of 1Msps and 12-bit precision, the oscilloscope captures waveform details accurately. The 1024-byte sampling buffer stores data for analysis, enabling effective observation of transient signals.

Bandwidth and sensitivity

Analog bandwidth spans 0-200KHz, with vertical sensitivity adjustable from 5mV/Div to 20V/Div in 1-2-5 increments. This range suits typical audio and control circuit signals.

Trigger and display

Trigger modes include automatic, conventional, and single, with rising or falling edge selection. The adjustable trigger level with indicator helps capture instant waveforms, and the negative delay allows viewing signals before the trigger point.

Input and coupling

The oscilloscope offers flexible input options to handle different signal types and voltage levels safely.

Input impedance and voltage

Input impedance is 1MΩ, with maximum input voltage of 50Vpp using a 1:1 probe and 400Vpp with a 10:1 probe. This protects the device while accommodating a wide range of signals.

Coupling choices

Coupling methods include DC, AC, and GND, providing control over how the input signal is conditioned before measurement.

Test signal and digital readout

A built-in 1KHz/3.3V square wave test signal source aids calibration and testing. Digital display shows waveform parameters: frequency, period, pulse width, duty cycle, maximum, minimum, average, peak-to-peak, and effective value.

Practical usage and value

The kit is designed for repeated use in training, demonstrations, and personal projects.

Waveform save and recall

Waveforms can be saved and recalled, and they persist after power-off. The HOLD function freezes the display for detailed analysis.

Kit contents and assembly

The package includes all shell oscilloscope parts, analog board chip components (pre-soldered and tested), a BNC fish clip probe, and assembly instructions. Users gain hands-on experience without complex soldering of sensitive ICs.

Why choose this product

This kit offers a cost-effective entry into oscilloscope use, combining learning with practical measurement. It is especially suitable for electronics courses, DIY repair shops, and hobbyist workshops.
