Setup

Initial Power On

1. Connect the power adapter to the device's power input and then to a suitable power source.
2. Press the OFF/ON button, typically located on the top right of the control panel, to power on the oscilloscope.
3. The display will illuminate, showing the boot-up sequence and then the main measurement interface.

Connecting Probes

1. Identify the CH1 and CH2 BNC connectors on the top of the device.
2. Connect your oscilloscope probes to the desired channel (e.g., CH1 for single-channel measurements or both for dual-channel).
3. Ensure the probe is securely fastened by twisting the BNC connector until it locks.
4. Connect the probe's ground clip to the ground of the circuit under test.

Operating Instructions

Basic Measurement

1. After connecting the probe to the signal source, press the Auto button. The oscilloscope will automatically adjust the vertical and horizontal scales to display a stable waveform.
2. Use the Left / and Right / buttons to navigate through menu options or adjust parameters.
3. The + and - buttons are used for fine-tuning values or selecting options within menus.

Triggering Modes

The SCO2 10M supports various triggering modes to capture specific parts of a waveform accurately. Access these modes via the Menu button and navigate to the Trigger settings.

• Edge Trigger: Triggers on a rising or falling edge of the input signal, suitable for most general-purpose measurements.
• Pulse Width Trigger: Triggers on pulses of a specified width, useful for analyzing digital signals.
• Video Trigger: Triggers on standard video signals, allowing for analysis of video waveforms.
• Slope Trigger: Triggers on a specific slope and direction of the signal, providing more control over trigger conditions.

Automatic Measurement

The device offers partial support for one-click automatic measurement. Press the Auto button to initiate automatic scaling and display of key waveform parameters such as Maximum Voltage (Max), Minimum Voltage (Min), Peak-to-Peak Voltage (Vpp), and Frequency (Fre).

Advanced Analysis (FFT, Histogram, Eye Diagram)

For in-depth signal analysis, navigate through the Menu to access advanced functions. These include Fast Fourier Transform (FFT) for frequency domain analysis, Histogram for statistical analysis of signal characteristics, and Eye Diagram analysis for assessing digital signal integrity.

Maintenance

Proper maintenance ensures the longevity and accuracy of your oscilloscope.

• Cleaning: Use a soft, dry, lint-free cloth to clean the device's exterior. For stubborn dirt, lightly dampen the cloth with water. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the casing or screen.
• Storage: Store the oscilloscope in a cool, dry place away from direct sunlight, extreme temperatures, and high humidity. Use the original packaging or a protective case for transport and storage.
• Probe Care: Handle oscilloscope probes carefully. Avoid bending or stressing the cables excessively, as this can damage the internal wiring. Keep probe tips clean and protected when not in use.

Troubleshooting

This section addresses common issues you might encounter with your oscilloscope.

No Display After Power On

• Check Power: Ensure the power adapter is securely connected to both the device and a functional power outlet.
• Battery: If the device is battery-powered, ensure the battery is sufficiently charged. Connect the power adapter to charge the battery.

Unstable Waveform

• Adjust Trigger: Press the Auto button to allow the oscilloscope to automatically set the trigger. Alternatively, manually adjust the trigger level and mode (e.g., Edge, Pulse Width) to stabilize the waveform.
• Probe Connection: Ensure probes are securely connected to the oscilloscope and the circuit under test. Verify that the probe's ground clip is properly connected.
• Signal Source: Verify that the signal source itself is stable and not intermittent.

Incorrect Measurements

• Probe Attenuation: Ensure the probe attenuation setting on the oscilloscope matches the physical probe (e.g., 1X, 10X). Mismatched settings will result in incorrect voltage readings.
• Calibration: If available in the menu, perform a self-calibration to ensure the device's internal settings are optimized.
