The Assembled DSO138 Digital Oscilloscope is an essential measuring instrument for electronics hobbyists and professionals looking for accuracy and convenience in a compact, ready-to-use device.
This oscilloscope features a 2.4-inch TFT LCD screen with a resolution of 320x240 pixels and the ability to display 262,000 colours, making waveform viewing clear and easy. Equipped with an ARM Cortex-M3 processor, it offers real-time sampling of up to 1Msps, allowing signals with an analogue bandwidth of up to 200 KHz to be captured.
The device includes a single channel with adjustable sensitivity from 10mV/Div to 5V/Div, with a sensitivity error of less than 5%, ensuring reliable measurements. The maximum input voltage is 50V peak, and the oscilloscope offers DC, AC and GND coupling modes to suit different types of signals.
Its technical features include:
- Channel: 1
- Analogue bandwidth: 0 - 200 KHz
- Sensitivity: 10mV/Div - 5V/Div
- Sensitivity error: < 5%
- Resolution: 12 bits
- Maximum input voltage: 50V peak
- Coupling modes: DC, AC, GND
- Maximum sampling rate: 1Msps
- Time base: 10us/Div - 500s/Div
- Record length: 1024 points
- Trigger modes: Automatic, Normal, Single
- Trigger types: rising and falling edge
- Fixed trigger position at the middle of the buffer
- Power supply: 9V DC (range 8 to 12V)
- Consumption: 120mA
- Dimensions: 117mm x 76mm x 15mm
This oscilloscope comes fully assembled and factory soldered, ready for immediate use, eliminating the need for assembly or complex setup. It also includes the probe and the cables needed to start measuring quickly and effectively.
It is ideal for viewing and analysing electrical signals in electronics projects, circuit repair, education and experimentation. Its compact size and low power consumption make it suitable for use in the lab, workshop or field.
The DSO138 digital oscilloscope is compatible with a range of electronic applications that require low-frequency signal analysis and accurate measurement of parameters such as period, pulse width, frequency, maximums, minimums and peak-to-peak voltages.
In summary, this unit offers an economical, practical and reliable solution for anyone needing an assembled digital oscilloscope with advanced features and ease of use.

Customer Questions & Answers
What are the dimensions, approximate weight and exactly what items are included in the box?
The unit measures 117 mm x 76 mm x 15 mm and has an approximate weight of less than 0.2 kg. The box contains the fully assembled oscilloscope, a test probe and connection cables. It does not include a power supply.
What power requirements does it need and what should I bear in mind to avoid damage?
It requires a 9 V DC supply, accepting an input range of 8 to 12 V. A stable power supply and correct polarity (centre positive) are recommended. Do not exceed 12 V or connect the wrong voltage, to avoid irreversible damage to the hardware.
What are the measurement tolerances and input voltage limits to ensure safe operation?
Sensitivity has an error of less than 5%. The maximum permitted input voltage is 50 V peak (Vpk); exceeding this value may damage the input circuit and put the user at risk.
What maintenance does it require and what common problems may arise during use, and how can they be solved?
It does not require frequent internal maintenance. It is advisable to keep the screen clean and prevent dust ingress. Common issues include no signal on the display (check power, cables and probe connection), or excessive noise (check the ground connection). If faults persist, it is recommended to inspect the solder joints or contact technical support due to the assembled nature of the device.
Does the oscilloscope come assembled or is it a kit to build?
The DSO138 digital oscilloscope comes fully assembled and factory soldered, ready for immediate use.
What type of screen does the DSO138 oscilloscope have?
It has a 2.4-inch TFT LCD screen with a resolution of 320x240 pixels and 262,000 colours.
What frequency range can this oscilloscope measure?
It has an analogue bandwidth from 0 to 200 KHz, suitable for low-frequency signals.
Does it include the probe and cables needed for use?
Yes, the product includes the probe and the cables needed to start measuring immediately.
What coupling modes does the oscilloscope support?
It supports DC, AC and GND coupling modes for different types of signals.
