With 10 GSa/s real-time sample rate (single-channel; 5 GSa/s dual; 2.5 GSa/s full four-channel), 1 Gpts of acquisition memory at single-channel mode (250 Mpts at full four-channel), UltraAcq® waveform mapping at ≥600,000 wfms/s standard (2,000,000 wfms/s in Sequence mode), and external display via HDMI plus full WebServer browser-based remote control over LAN, the UPO7104L is an eight-in-one bench platform consolidating oscilloscope, spectrum analyzer, DVM, frequency counter, AWG, multi-bus protocol analyzer, power analyzer, and jitter analyzer with eye diagram (some functions require optional license unlocks — see Detailed Features below). For ATE system integration, multi-instrument bench rack consolidation, high-channel-count parallel test, and engineering-validation environments where a 1U headless oscilloscope solves a rack-density problem that benchtop scopes cannot, the UPO7104L is the entry SKU into UNI-T’s UPO7000L line. Calculated rise time of 350 ps resolves leading-edge content on wide-bandgap (GaN, SiC) switching devices and high-speed digital interface characterization. Selectable 50 Ω / 1 MΩ inputs (1 MΩ caps at 500 MHz) bring RF-grade signal-chain options to the same channel front end. Multi-machine synchronization up to 128 units / 512 channels supports parallel test architectures where benchtop scopes hit a channel-count ceiling. Key Features 1 GHz Bandwidth, 4 Analog Channels + 1 EXT — Four-channel acquisition at up to 1 GHz with 10 GSa/s peak sample rate (single-channel), 2.5 GSa/s at full four-channel, and calculated rise time of 350 ps. Selectable 50 Ω / 1 MΩ inputs (1 MΩ caps at 500 MHz) support both general-purpose probing and direct RF-grade 50 Ω signal-chain work on the same channel front end. 10 GSa/s Sample Rate, 1 Gpts Memory, UltraAcq® Acquisition — Peak 10 GSa/s (single-ch) / 5 GSa/s (dual) / 2.5 GSa/s (full four-ch) with corresponding 1 Gpts / 500 Mpts / 250 Mpts memory depth, all standard configuration. UltraAcq® multi-body cross-mapping with sub-1 µs dead time delivers ≥600,000 wfms/s standard and 2,000,000 wfms/s in Sequence mode. High Resolution Mode and FPGA-Resident ERes — 8-bit native ADC with two paths to higher effective vertical resolution: HR mode (12 effective bits via averaging, full sample rate retained) and ERes (acquisition menu, FPGA-resident FIR filter, +3 bits on band-limited signals). UPO7000L is the only UNI-T scope where ERes is acquisition-domain rather than Math-menu. 1U Headless Rack-Mount Form Factor — 214 mm × 43 mm × 500 mm,
