UNI-T UTD1025DL Handheld Oscilloscope
The UNI-T UTD1025DL is a compact handheld digital storage oscilloscope combining dual-channel waveform acquisition with built-in multimeter capabilities. It offers a 25 MHz bandwidth and up to 250 MS/s real-time sampling rate per channel, enabling capture of a wide range of signals in field and lab environments. The unit’s intuitive front-panel layout and one-button Auto Setup streamline measurements: upon signal input, vertical scale, timebase, and trigger adjust automatically for a stable display. A high-contrast color TFT LCD supports outdoor use, and isolated USB connectivity allows safe PC communication for data transfer or firmware updates.
Memory depth and record functions permit waveform storage and recall, while auto measurements (22 types) facilitate rapid parameter analysis. The oscilloscope runs on rechargeable battery for up to 6 hours, making it suitable for portable diagnostics. Integrated multimeter functions (voltage, current up to 4 A, resistance, capacitance, diode, continuity) further enhance versatility. Unique features such as Peak Detect for narrow pulses and AVG mode for noise reduction aid in capturing elusive or noisy signals. FFT and math operations on dual channels support frequency-domain analysis.
Overall, the UTD1025DL is designed for ease of use, reliable performance, and multi-function utility in electronics troubleshooting and testing.
