This manual provides essential information for the safe and efficient operation of your DSO2D15 oscilloscope. Please read it thoroughly before use and retain it for future reference.

2. Safety Information

Always observe the following safety precautions to prevent injury and avoid damage to the instrument or connected devices.

• Power Source: Ensure the oscilloscope is connected to a power source within the specified voltage range (100-240V AC, 50/60Hz). Use only the provided power cord or an approved equivalent.
• Grounding: The instrument must be properly grounded to prevent electric shock. Do not defeat the grounding feature of the power plug.
• Environmental Conditions: Operate the oscilloscope in a dry, well-ventilated area. Avoid exposure to extreme temperatures, humidity, dust, or corrosive gases.
• Hazardous Voltage: Hazardous voltages are present inside the device. Do not remove the cover unless performed by qualified service personnel. Refer to the warning label on the rear panel.
• Probes: Use only probes rated for the voltage and frequency being measured. Ensure probes are properly connected before making measurements.
• Cleaning: Disconnect power before cleaning. Use a soft, damp cloth. Do not use abrasive cleaners or solvents.
• Servicing: Refer all servicing to qualified personnel.

3. Setup

3.1 Unpacking and Inspection

Carefully unpack the oscilloscope and all accessories. Inspect for any signs of damage during transit. If any damage is found, contact your supplier immediately.

3.2 Package Contents

The standard package for the Hantek DSO2D15 includes the following items:

• Hantek DSO2D15 Oscilloscope Unit
• 1 PP150B 150MHz Probe
• 1 Hantek PP150 100MHz Probe (for 2nd channel)
• 1 USB Cable

3.3 Power Connection

1. Connect the provided power cable to the AC input on the rear panel of the oscilloscope.
2. Plug the other end of the power cable into a grounded AC power outlet.
3. Ensure the power switch (usually located near the AC input) is in the OFF position before connecting to power.

3.4 Probe Connection

Connect the oscilloscope probes to the BNC input connectors on the front panel (CH1, CH2). Ensure a secure connection by twisting the BNC connector until it locks.

Before making measurements, perform probe compensation to ensure accurate readings. Refer to the "Probe Compensation" section in the Operating Instructions.

4. Operating Instructions

4.1 Powering On/Off

1. To power on, press the power switch located on the rear panel. The display will illuminate, and the system will boot up.
2. To power off, press the power switch again.

4.2 Front Panel Overview

The front panel of the DSO2D15 features a large display, control buttons, and input connectors. Familiarize yourself with the layout for efficient operation.

4.3 Basic Oscilloscope Functions

• Vertical Controls: Adjust voltage per division (Volts/Div) and vertical position for each channel (CH1, CH2).
• Horizontal Controls: Adjust time per division (Sec/Div) and horizontal position to control the time base.
• Trigger System: Use the trigger controls to stabilize waveforms. Select trigger type (Edge, Pulse, Video, Slope, etc.), source, and level. The DSO2D15 offers 14 kinds of trigger modes.
• Acquisition Mode: Select between Normal, Peak Detect, and Average modes for waveform acquisition.
• Measurements: Access automatic measurement functions (32 kinds available) to display parameters like frequency, period, Vpp, Vmax, Vmin, etc.
• Serial Protocol Decoding: The unit supports 5 kinds of serial protocol decoding. Refer to the on-screen menu for specific setup and analysis.

4.4 DDS Waveform Generator

The DSO2D15 includes a built-in 25MHz DDS waveform generator. This generator can produce various standard waveforms (sine, square, triangle, etc.) for testing circuits.

1. Connect the DDS output (labeled EXT TRIG/GEN OUT) to the circuit under test.
2. Access the generator menu via the front panel controls.
3. Select the desired waveform type, frequency, amplitude, and offset.
4. Enable the output to generate the waveform.

Note: The built-in DDS generator is suitable for general testing but should not be confused with a dedicated arbitrary waveform generator for complex signal generation.

5. Maintenance

5.1 General Care

• Keep the instrument clean and dry.
• Avoid dropping or subjecting the unit to strong impacts.
• Store in a dust-free environment when not in use.

5.2 Cleaning

To clean the exterior of the oscilloscope:
