Digital Storage Oscilloscope Experimenter's Version - 1 MHz / 5 Msps
Description
The Digital Storage Oscilloscope Experimenter's Version is a highly cost-effective, microcontroller-based
digital storage oscilloscope engineered for electronics enthusiasts, students, and workshop bench testing. Compact and versatile,
it features a 1 MHz analogue bandwidth with up to 5 Msps real-time sampling rate, making it an ideal tool for audio signal
tracing, low-frequency waveform analysis, and educational project builds. Non-volatile internal memory allows you to store
up to six waveform captures directly to EEPROM, retaining your data even after power-down, while onboard serial connectivity
enables bitmap screen exports directly to a PC.

Suggested Uses & Applications:
- Audio Signal Tracing: Diagnosing amplifier gain stages, pre-amp circuits, active filter networks, and synthesiser audio paths.
- Educational & STEM Training: Learning basic oscilloscope operations, waveform characteristics, and microcontroller signal analysis.
- Embedded Test Fixtures: Integrating a permanent, dedicated scope display into custom equipment enclosures, modular synthesiser racks, or testing stations.
- General Hobbyist Testing: Checking low-frequency clock lines, PWM control signals, and sensor outputs on microcontrollers.
Power Supply & Operating Warnings:
- Power Supply Required: Operating this unit requires a 9 V DC 1 A (1000 mA) regulated power adapter with a centre-positive 2.1 mm barrel connector (not included). Verify power supply polarity prior to switching on.
- Maximum Input Voltage Limit: Do not exceed the maximum input voltage of 50 Vpp when using a standard 1x probe. Exceeding input limits will damage the analogue front-end and microcontroller.
- Frequency Counter Input Level: The integrated frequency counter mode is designed exclusively for digital TTL-level signals (0 - 5 V).
