Description
UNI-T UTD1102C Handheld Oscilloscope
The UNI-T UTD1102C is a handheld digital storage oscilloscope in the UTD1000 series, offering a 100 MHz analog bandwidth and up to 500 MS/s real-time sampling rate on two channels. Housed in a compact, portable case, it features a 5.7 inch (320×240 pixel) color LCD that provides clear waveform viewing and analysis. Its user interface mimics traditional bench oscilloscope controls dedicated scaling and position knobs, plus an [AUTO] key for one-touch waveform setup allowing technicians to operate it with minimal learning time.
Internally, an 8-bit A/D converter captures up to 512 kpts per channel (1 Mpt total), with selectable acquisition modes (sampling, peak detect, or average) and an equivalent-time sampling mode (up to 25 GS/s) for high-resolution at very fast time bases . The instrument’s front panel offers dual-channel vertical controls (5 mV/div – 50 V/div), horizontal time bases (5 ns/div – 50 s/div for 100 MHz model), and a comprehensive trigger menu (edge, pulse, video, alternate) for capturing both repetitive and single-shot events. Auxiliary functions include FFT, arithmetic operations, a two-channel multimeter, and on-screen parameter measurements of up to 27 waveform metrics.
Powered by an internal Li-ion battery (3 hrs run time) or external AC adaptor, the UTD1102C combines full bench-scope functionality with rugged portability for field diagnostics and educational use .
