Key ports include:

• AFG Output: For the built-in DDS signal generator.
• CH1-CH4: Four oscilloscope input channels.
• USB Interface: For connection to a computer for data transfer and secondary analysis.
• Power Input: For connecting the power adapter.

5. Setup

Follow these steps to set up your Boartechs TO1204D Digital Oscilloscope:

1. Power Connection: Connect the provided power adapter to the oscilloscope's power input port and then to a suitable power outlet.
2. Probe Connection: Connect the oscilloscope probes to the desired input channels (CH1-CH4) on the rear panel. Ensure a secure connection.
3. Grounding: Always connect the ground clip of the probe to the ground point of the circuit under test before connecting the probe tip to the signal point.
4. Power On: Press the power button to turn on the oscilloscope. The device will boot up and display the main interface.

6. Operating Instructions

The TO1204D offers various functions accessible via its touch screen and dedicated buttons.

6.1 Basic Oscilloscope Operation

• One-Button Automatic Adjustment: The oscilloscope is equipped with an efficient one-button automatic function. Press the dedicated 'Auto' button or select the 'Auto' option on the screen to automatically adjust vertical, horizontal, and trigger settings to display the measured waveform clearly. This eliminates tedious manual adjustments.
• Vertical Scale (Volts/Div): Adjust the vertical scale to control the amplitude of the displayed waveform. Use the touch screen controls or dedicated knobs (if present) to change the Volts/Div setting for each channel.
• Horizontal Scale (Time/Div): Adjust the horizontal scale to control the time base of the displayed waveform. This changes the time represented by each horizontal division on the grid.
• Trigger Settings: Configure the trigger level, mode (e.g., Edge, Pulse), and source to stabilize repetitive waveforms.

6.2 Measurement Functions

• Cursor Measurement: Utilize the cursor measurement function for convenient manual measurement of waveform parameters such as period, frequency, and voltage. Activate cursors from the measurement menu and drag them on the screen to the desired points.
• Automatic Measurements: The oscilloscope can perform various automatic measurements (e.g., Vpp, Vmax, Vmin, Freq, Period, Rise Time, Fall Time). Select these from the measurement menu.

6.3 Signal Generator (DDS)

The built-in DDS signal generator can output various waveforms. Access the signal generator function from the main menu. Configure waveform type (e.g., Sine, Square, Triangle), frequency, and amplitude using the touch screen controls. Connect the AFG output port to your circuit.

6.4 Multimeter Function

Switch to the multimeter mode to perform basic electrical measurements such as voltage, current, and resistance. Connect test leads to the appropriate multimeter input jacks (V/Ω/C, COM, mA, A) located on the side panel.

6.5 Data Storage and Connectivity

• Waveform Saving: The device includes 1GB of built-in storage space. Use the 'Save' function to store waveforms and screen captures.
• USB Interface: Connect the oscilloscope to a computer using the provided USB cable. This allows for secondary analysis of captured waveforms and data transfer using compatible software.

6.6 FFT Display Function

The FFT (Fast Fourier Transform) display function allows you to analyze the frequency spectrum characteristics of a signal. Activate FFT mode from the display or analysis menu to view the signal in the frequency domain.

7. Maintenance

Proper maintenance ensures the longevity and accuracy of your oscilloscope.

• Cleaning: Clean the oscilloscope's exterior with a soft, damp cloth. Do not use abrasive cleaners or solvents. For the screen, use a screen-specific cleaning solution and a microfiber cloth.
• Storage: When not in use, store the oscilloscope in a dry, dust-free environment, away from direct sunlight and extreme temperatures.
• Probe Care: Handle probes carefully. Avoid bending or stressing the probe cables. Store probes properly to prevent damage.
• Calibration: Periodic calibration by qualified service personnel is recommended to maintain measurement accuracy.

8. Troubleshooting

If you encounter issues with your oscilloscope, refer to the following common problems and solutions:

• No Power:
  • Ensure the power adapter is securely connected to both the oscilloscope and a working power outlet.
  • Check if the power outlet is functional.
• No Waveform Display:
  • Verify that the probe is correctly connected to the input channel and the circuit under test.
  • Check the probe's attenuation setting (1X, 10X) and ensure it matches the oscilloscope's setting.
  • Use the 'Auto' button to automatically adjust settings.
  • Adjust the vertical (Volts/Div) and horizontal (Time/Div) scales.
  • Check trigger settings; ensure the trigger level is within the signal's amplitude.
• Unstable Waveform:
  • Adjust the trigger level and trigger mode.
  • Ensure the signal is stable and within the oscilloscope's bandwidth.
• Touch Screen Unresponsive:
  • Restart the device.
  • Ensure the screen is clean and free of debris.

If the problem persists, contact customer support.
