Setup

Initial Charging:

Before first use, fully charge the oscilloscope using the provided USB Type-C cable and a 5V 1A USB power adapter (not included). The charging indicator on the device will show charging status.

Connecting the Probe:

1. Ensure the oscilloscope is powered off.
2. Connect the BNC connector of the probe cable to the probe input port on the oscilloscope.
3. Attach the ground clip of the probe to the ground reference of the circuit under test.
4. Connect the probe tip to the test point on the circuit.

Powering On:

Press and hold the power button (usually located at the bottom or front) until the display illuminates. The device will boot up and display the main measurement interface.

Operating Instructions

Basic Measurement:

Once powered on and the probe is connected, the oscilloscope will display the waveform. The screen shows parameters such as Frequency (Freq), Period (Peri), Duty Cycle (Duty), Vmax, Vmin, Vpp, and Amplitude (Amp).

AUTO Setting:

Press the AUTO button for automatic parameter adjustment. This feature quickly optimizes the display for the input signal, making it easy to view waveforms without manual configuration. Long press the AUTO button to quickly calibrate the baseline.

Trigger Modes:

The DSO153 supports three trigger modes:

• AUTO: Automatically triggers the waveform, suitable for most periodic signals.
• Normal: Triggers only when the signal meets the set trigger conditions. Useful for stable waveforms.
• Single: Captures a single waveform when the trigger condition is met, then stops. Ideal for non-repeating signals.

Trigger Slope: Select between Rising or Falling edge triggering using the appropriate controls.

Coupling Mode:

Choose between AC and DC coupling:

• AC Coupling: Blocks the DC component of the signal, allowing only the AC component to be displayed.
• DC Coupling: Displays both the AC and DC components of the signal.

Signal Generator Function:

The oscilloscope includes a built-in signal generator capable of producing various waveforms:

• Frequency: 0-10KHz
• Duty Cycle: 0-100% (for Square and Sawtooth waves)
• Amplitude: 0.1-3.3V
• Waveforms: Sine, Square, Sawtooth (Half, Full), Positive Step, Inverse Step, Noise, Exponential Rise, Exponential Fall, DC, Sink Pulse, Lorentz.

Specifications

Maintenance

Cleaning:

Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure no liquids enter the device openings.

Battery Care:

To prolong battery life, avoid fully discharging the battery frequently. Recharge the device regularly, especially if it will be stored for an extended period.

Automatic Shutdown:

The DSO153 features an automatic shutdown function to conserve power. This can be configured in the device settings. After a period of inactivity, the device will automatically power off.
