Hantek DSO2D15 Digital Oscilloscope User Manual

3.1 Déballage et inspection

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

3.2 Connexion d'alimentation

1. Ensure the power switch on the oscilloscope is in the OFF position.
2. Connect the provided power cable to the power input port on the rear of the oscilloscope.
3. Plug the other end of the power cable into a grounded AC power outlet. The oscilloscope supports 100-240VAC RMS, 45-440Hz.

3.3 Connexion et compensation de la sonde

1. Connect the BNC end of the oscilloscope probe to one of the input channels (CH1 or CH2) on the front panel.
2. Attach the probe tip to the probe compensator output terminal (typically a square wave output) on the front panel.
3. Allumez l'oscilloscope.
4. Adjust the probe compensation until a flat-top square wave is displayed on the screen. This ensures accurate measurements.

4.1 Panneau de configuration terminéview

The front panel of the DSO2D15 is intuitively designed for ease of use. It consists of the display, function buttons (F0-F6), menu buttons, vertical controls (VOLTS/DIV, POSITION), horizontal controls (SEC/DIV, POSITION), trigger controls, and input channels.

4.2 Fonctions de l'oscilloscope

4.2.1 Dual Channel Operation

The DSO2D15 features two independent input channels (CH1 and CH2), each with its own vertical scale (VOLTS/DIV) and position control. This allows for simultaneous observation and comparison of two different signals.

4.2.2 Triggering System

The trigger system stabilizes repetitive waveforms and captures single-shot events. The DSO2D15 offers a wide range of trigger types:

• Standard Triggers: Edge, Pulse, Video, Slope, Timeout, Window, Pattern, Interval, Undervoltage.
• Serial Protocol Triggers: UART, LIN, CAN, SPI, IIC.

Use the "TRIGGER" section controls to select trigger type, level, and mode (Auto, Normal, Single).

4.2.3 Measurement and Statistical Functions

The oscilloscope provides 32 automatic measurement parameters, including Frequency, Period, Average, Peak-to-Peak, RMS, Min, Max, Rise Time, Fall Time, and various duty cycles. Statistical analysis provides real-time calculations of minimum, maximum, and standard deviation for measurements.

4.2.4 Saving and Recalling Data

The DSO2D15 allows users to save various data types, including instrument settings, captured waveforms, reference waveforms, CSV data, and screenshots (images). Use the "SAVE/RECALL" and "SAVE TO USB" buttons for these operations.

4.3 Waveform Generator Function

The built-in 1-channel 25MHz arbitrary waveform generator can produce various standard waveforms (Sine, Square, Pulse, Triangle, Sample Wave, Exponential Wave, Noise) and user-defined arbitrary waveforms (Arb1-Arb4). This function is useful for testing circuits and systems.

• Onde sinusoïdale : Frequency Range 0.1Hz~25MHz
• Square/Pulse Wave: Frequency Range 0.1Hz~10MHz
• Triangle Wave: Frequency Range 0.1Hz~1MHz
• Arbitrary Wave: Frequency Range 0.1Hz~10MHz

Access the waveform generator settings via the dedicated "WAVE GEN" button or menu option.
