6. Operating Instructions
This section provides an overview of basic operating procedures. Refer to the software's built-in help for detailed instructions on advanced features.
6.1 Basic Waveform Display
- Channel Selection: In the software interface, enable the desired channels (CH1-CH4) for measurement.
- Vertical Scale (Volts/Div): Adjust the vertical scale to fit the signal amplitude on the screen.
- Horizontal Scale (Time/Div): Adjust the horizontal scale to view the desired number of signal cycles.
- Trigger Settings: Configure the trigger source, type (edge, pulse, video, etc.), and level to stabilize the waveform display.

6.2 Arbitrary Waveform Generator (AWG)
- Connect a BNC cable from the 'GEN OUT' port on the oscilloscope to the input of the circuit requiring a signal.
- In the software, navigate to the AWG control panel.
- Select the desired waveform type (sine, square, triangle, arbitrary), frequency, amplitude, and offset.
- Enable the output to generate the signal.

6.3 Advanced Functions
- Pass/Fail Test: Set up masks to automatically check if a waveform falls within defined limits.
- Dynamic Cursor Tracking: Use cursors to precisely measure voltage and time parameters on the waveform.
- Waveform Record and Replay: Capture and store long waveform sequences for later analysis.
- FFT Analysis: Access the FFT function in the software to view the frequency spectrum of your signals.
7. Maintenance
Proper maintenance ensures the longevity and accuracy of your Hantek 6254BD oscilloscope.
- Cleaning: Use a soft, dry cloth to clean the exterior of the device. For stubborn dirt, a slightly damp cloth with mild detergent can be used, ensuring no liquid enters the device. Do not use abrasive cleaners or solvents.
- Storage: Store the oscilloscope in a clean, dry environment away from direct sunlight, extreme temperatures, and high humidity. Disconnect all probes and cables before storage.
- Probe Care: Handle probes carefully. Avoid bending or kinking the cables. Store probes properly to prevent damage to the tips.
