Offered by baba tools through https://babaocamachine.com, this advanced digital handheld oscilloscope combines three essential electronics tools into a single, easy-to-use instrument.
At its core, the FNIRSI DSO-TC3 functions as a digital handheld oscilloscope with a 10MS/s sampling rate and 500kHz bandwidth, making it ideal for analyzing low- to mid-frequency signals commonly encountered in electronics repair, embedded development, and mobile repair tools applications. Whether you are diagnosing power supply ripple, checking clock signals, or troubleshooting signal integrity issues, this oscilloscope delivers stable, reliable waveform visualization with automatic waveform display and intelligent trigger handling.
The high-quality 2.4-inch color TFT display ensures clear visibility of waveforms and measurement data, even during extended use. With AC/DC coupling, a vertical sensitivity range from 10mV/Div to 10V/Div, and wide voltage measurement capability of ±40V with a 1:1 probe and ±400V with a 10:1 probe, the FNIRSI DSO-TC3 adapts easily to a wide range of electronics products and testing scenarios. This flexibility makes it a valuable addition to any electronics tools kit, from lab benches to field service bags.
Trigger precision is another strong point of the FNIRSI DSO-TC3 3 in 1 oscilloscope. It supports Auto, Normal, and Single trigger modes, along with rising edge and falling edge trigger types, allowing you to lock onto stable signals or capture transient events with confidence. These features are especially useful for phone repair tools and mobile repair tools workflows, where fast and accurate fault detection can save significant time.
Beyond its oscilloscope functionality, the FNIRSI DSO-TC3 integrates a smart transistor tester capable of automatically identifying and measuring a wide variety of electronic components. This includes transistors, diodes, resistors, capacitors, and other passive components. The automatic detection and clear on-screen results make component testing fast and intuitive, even for complex circuits. For electronics repair professionals and enthusiasts alike, this feature eliminates the need for multiple standalone testers, streamlining daily work and reducing tool clutter.
The third core function of the FNIRSI DSO-TC3 is its DDS signal generator, which provides six types of output waveforms: sine, square, pulse, triangle, ramp, and DC. With an output amplitude of 0–3.3V and an adjustable duty cycle from 0–100% for rectangular and sawtooth waves, the signal generator is perfect for signal injection, circuit testing, and functional verification. This makes the device exceptionally useful for electronics products development, educational labs, and practical training environments.
Designed for portability, the FNIRSI DSO-TC3 digital handheld oscilloscope features a built-in rechargeable battery, enabling true handheld operation without constant reliance on external power. This is particularly beneficial for on-site diagnostics, quick bench checks, and mobile repair scenarios. The ergonomic handheld design ensures comfortable use, while the intuitive interface reduces the learning curve for new users.
In terms of physical size, the FNIRSI DSO-TC3 is compact and travel-friendly, with approximate dimensions of 5.1 inches × 3.1 inches × 1.2 inches, making it easy to carry in a toolkit or backpack. Despite its small footprint, it delivers professional-grade performance suitable for a wide range of electronics tools applications.
From mobile phone repair and consumer electronics servicing to educational use and DIY electronics projects, the FNIRSI DSO-TC3 3-in-1 Digital Handheld Oscilloscope stands out as a cost-effective, space-saving, and highly capable solution. Its combination of oscilloscope, transistor tester, and DDS signal generator functions addresses the real-world needs of modern electronics work, all in one reliable device.
When you choose the FNIRSI DSO-TC3 from baba tools, you’re investing in a practical, professional-grade instrument designed to support precision diagnostics and efficient workflows. Whether you are a seasoned technician or an aspiring electronics enthusiast, this FNIRSI DSO-TC3 oscilloscope is a smart addition to your electronics tools collection.
