TheUTD1202Cis a compact, handheld digital storage oscilloscope offering two channels of 200 MHz analog bandwidth. Incorporating Uni-Trends Ultra Phosphor display, it renders up to 256 levels of grayscale to highlight subtle waveform variations and transient anomalies. Each channel samples at 1 GS/s into a 56 Mpt deep memory, enabling detailed captures over extended time spans without sacrificing resolution. A Fast Acquire mode reaches up to 500,000 wfms/s, ensuring even infrequent events are recorded.
Hardware-based waveform recording stores up to 100,000 frames for later review, while an enhanced 1 Mpt FFT allows frequency-domain analysis with adjustable windowing and markers. The 7, 800 480 TFT LCD provides clear visualization, and front-panel jog dials and softkeys simplify navigation. Trigger options span edge, pulse-width, video, slope, runt, over-amplitude, delay, timeout, duration, setup/hold, Nth-edge, and pattern, supplemented by on-board hardware decoding for RS232, IC, SPI, CAN, and LIN buses. A built-in dual-channel DVM offers AC/DC TRMS measurements, and a 7-digit counter enables precise frequency measurement.
Connectivity includes USB Host/Device, LAN, EXT Trig, and AUX Out (Trig Out/Pass/Fail). Web-based remote control via the integrated HTTP server facilitates networked operation and waveform sharing, making the UTD1202C ideal for field diagnostics, education, and development tasks.
