Description
UNI-T UPO1104 Digital Oscilloscope 100MHz 4 Channel
The UNI-T UPO1104 is a 100 MHz, 4-channel digital phosphor oscilloscope designed to offer deep memory, high waveform capture rates, and real-time recording/playback with a 256-level grayscale display. It employs UNI-T’s Ultra Phosphor 2.0 technology, enabling clear visualization of transient events and fine waveform detail. With a maximum real-time sampling rate of 2 GSa/s (single channel) and a maximum memory depth of 56 Mpts, the UPO1104 can sustain high sampling rates across broad time-base settings while capturing up to 500,000 wfms/s in Fast Acquire mode.
Hardware-based, uninterrupted waveform recording can store up to 120,000 frames for later review. Each of its four analog channels features low baseline noise (<100 μVrms), a vertical scale range from 500 μV/div to 20 V/div, and 8-bit resolution, optimized for precise signal observation. The integrated DVM module supports AC/DC TRMS measurements, and 36 automatic waveform‐parameter measurements can be performed within both screen and cursor‐selected areas.
Rich triggering options (edge, pulse width, video, slope, runt, over‐amplitude, delay, timeout, duration, setup/hold, Nth-edge, code pattern) and full‐memory hardware decoding for RS232, I2C, and SPI facilitate complex signal analysis. Network and USB connectivity enable remote control, data storage, and SCPI programmability.
