The probes supplied with the oscilloscope are crucial for accurate measurements. Ensure the probe's attenuation setting (e.g., 1X or 10X) matches the setting on the oscilloscope for correct readings. The P4100 probe, for instance, offers a 100X attenuation ratio and is designed for high voltage applications up to 2000Vp.p.
4. Setup
Follow these steps to set up your Hantek DSO2C10 oscilloscope for initial use.
- Unpacking: Carefully remove the oscilloscope and all accessories from the packaging. Inspect for any signs of damage.
- Power Connection: Connect the supplied power cord to the AC input on the rear panel of the oscilloscope and then to a grounded power outlet.
- Power On: Press the power button located on the front panel to turn on the oscilloscope. The device will perform a self-test and display the main waveform interface.
- Probe Connection:
- Connect the BNC connector of a probe to one of the input channels (CH1 or CH2) on the front panel.
- Ensure the probe's attenuation switch (e.g., 1X/10X) is set to the desired ratio.
- Probe Compensation:
- Connect the probe tip to the probe compensation test point (usually a square wave output) on the front panel and the ground clip to the ground terminal.
- Adjust the compensation trimmer on the probe until a flat-top square wave is displayed on the screen. This ensures accurate signal reproduction.
5. Operating Instructions
This section covers the basic operation and key features of the DSO2C10 oscilloscope.
5.1 Basic Measurements
To perform a basic voltage and time measurement:
- Connect Probe: Connect a compensated probe to the signal source and the oscilloscope input channel.
- Auto Set: Press the AUTO SET button. The oscilloscope will automatically adjust vertical, horizontal, and trigger settings to display a stable waveform.
- Adjust Vertical Scale (VOLTS/DIV): Use the VOLTS/DIV knob for the active channel to adjust the vertical scale (voltage per division) to fit the waveform on the screen.
- Adjust Horizontal Scale (SEC/DIV): Use the SEC/DIV knob to adjust the horizontal scale (time per division) to view the desired number of cycles.
- Position Adjustment: Use the POSITION knobs for vertical and horizontal axes to move the waveform on the screen.

5.2 Triggering
Triggering stabilizes repetitive waveforms and captures single-shot events. The DSO2C10 offers various trigger modes.
- Trigger Level: Use the TRIGGER LEVEL knob to set the voltage level at which the oscilloscope captures the waveform.
- Trigger Mode: Access trigger settings via the TRIGGER MENU button to select modes like Edge, Pulse, Video, Slope, etc.
- Trigger Source: Select the input channel (CH1, CH2, EXT) or the internal signal generator as the trigger source.
5.3 Advanced Features
- Arbitrary Waveform Output: The DSO2C10 supports arbitrary waveform output, allowing users to generate various test signals. Refer to the WAVE GEN section of the menu for configuration.
- Serial Protocol Triggers and Decodes: The device includes standard support for 5 kinds of serial protocol triggers and decodes, useful for debugging embedded systems and communication interfaces. Access these features through the DECODE menu.
- Memory Depth: With an 8M memory depth, the oscilloscope can capture longer signal durations at high sample rates, enabling detailed analysis of transient events.
- Measurement Functions: Utilize the MEASURE menu to display automatic measurements such as Vpp, Vmax, Vmin, Freq, Period, Rise Time, Fall Time, etc.
