UPO7104L 1 GHz 4Ch Eight-in-One Rack-Mount Oscilloscope

The UPO7104L is a 1 GHz, four-channel digital storage oscilloscope in a 1U headless rack-mount form factor, engineered for high-density ATE rack integration and multi-instrument system test. 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

Detailed Features

Windows 10 Platform with WebServer Remote Control

The UPO7000L runs Windows 10 IoT Ent LTSC 64-bit on an Intel Core i5-7200U at 2.5 GHz with 8 GB RAM and a 128 GB SSD — a real general-purpose computing platform under the instrument, not an embedded shell. The built-in WebServer provides browser-based remote control from PC or smartphone via IP address, supporting two layout styles (PC-grade and smartphone-grade) without driver installation. Full SCPI command set (USBTMC) over USB Device or LAN supports script-driven automated test sequences for ATE integration. On-instrument MATLAB and Python pipelines handle post-processing without round-tripping captures to a host computer.

Deep Memory — Up to 1 Gpts Standard

The 1 Gpts memory depth holds the longest acquisition windows in the UPO7000L line at single-channel mode — capturing tens of thousands of waveforms in a single acquisition for post-event analysis. At dual-channel mode, memory remains 500 Mpts; at full four-channel, 250 Mpts. For ATE rack integration where customers need standard-configuration deep memory rather than priced-up options on competing rackmount instruments, the deep memory budget is a flagship-grade specification at the 1 GHz entry tier.

Vertical Resolution — 8-Bit Native with HR Mode and FPGA-Resident ERes

The UPO7104L delivers up to 1 GHz of bandwidth at 10 GSa/s on an 8-bit acquisition front end, with two distinct paths to higher effective vertical resolution — both available without leaving the acquisition menu. High Resolution mode applies single-acquisition moving averaging to reach up to 12 effective bits at the full sample rate, useful for general-purpose noise reduction on switching ripple, sensor outputs, and jitter work. Enhanced Resolution (ERes) on the UPO7000L is FPGA-resident, processing waveforms directly in hardware via FIR filtering for up to 3 additional bits on band-limited signals (each 0.5-bit improvement halves usable sample rate). Unlike the MSO7000X — where ERes lives in the Math menu and operates as a post-acquisition math operation — ERes on the UPO7000L operates on the acquired stream itself, so the resolution enhancement is available on single-shot signals, repetitive signals, and aperiodic signals alike, with no math-domain conversion step. This is the highest-resolution path available in UNI-T’s 1U rackmount form factor.

Built-In Spectrum Analyzer — Enhanced FFT to 1 Mpts

The standard enhanced-FFT spectrum analyzer covers the full oscilloscope analog bandwidth with up to 1 Mpts FFT length and multiple view types (amplitude, power, PSD, real, imaginary, phase). Two spectrum-view windows can run simultaneously across five window functions (Rectangular, Hanning, Blackman, Hamming, Flattop) — for harmonic ID, EMI pre-compliance sweeps, and modulated-signal analysis from within the same 1U rack-mount instrument as the scope acquisition.

60 MHz Single-Channel Function/Arbitrary Waveform Generator (Optional)

The optional UPO7000L-AWG package adds a 60 MHz single-channel function/arbitrary waveform generator (16-bit, 625 MSa/s) with sine, square, pulse, ramp, noise, DC, and 200+ pre-loaded arbitrary waveforms plus a custom-waveform editor. Modulation and sweep modes support stimulus-response work, closed-loop stability sweeps paired with UPO7000L-PWR, and time-correlated stimulus-and-capture testing alongside scope acquisition — from within the same 1U rack-mount instrument.

Applications

For R&D Engineers

• For 1 GHz R&D validation in shared-lab environments where rack space is at a premium, the UPO7104L covers high-speed MCU and FPGA reference design debug, four-channel time-correlated acquisition, high-speed digital interface characterization (DDR3/4 region, faster serial buses), and 11-protocol decode across computer, automotive, audio, and aerospace bus families — all from a 1U headless instrument under WebServer remote control.
• Time-correlated four-channel acquisition under WebServer remote control from any browser, supporting shared-lab and rack-based engineering environments where bench surface is at a premium.
• Eleven-protocol decode covering computer, automotive (CAN/CAN-FD/LIN/FlexRay/SENT), audio, and aerospace (MIL-STD-1553/ARINC 429) bus families with integrated trigger and decode.
• UltraAcq® Sequence mode at 2,000,000 wfms/s for rare-event hunting on intermittent timing anomalies and signal-integrity work where 200,000 wfms/s scopes miss the event between redraws.

For ATE Integrators and Test Labs

• For ATE system integrators, design consultancies, and test labs running parallel high-channel-count test at the 1 GHz tier, the UPO7104L consolidates oscilloscope, spectrum analyzer, protocol decoder, AWG (optional), jitter and eye-diagram analyzer (optional), and power analyzer (optional) into a 1U rackmount footprint with multi-machine sync up to 128 units / 512 channels — reducing rack count, calibration overhead, and integration complexity vs benchtop alternatives. The 11-protocol decode set including aerospace (MIL-STD-1553, ARINC 429) supports customer-design validation in regulated industries.
• Multi-machine synchronization up to 128 units / 512 channels with 200 ps RMS inter-instrument jitter for parallel high-channel-count test architectures impossible with benchtop scopes.
• 1U half-width rack-mount form factor (two instruments per full-width slot) integrates into ATE racks alongside other 1U/2U test equipment; HDMI external display + WebServer remote control eliminate operator-presence requirements at the rack.
• Standard mask & limit testing with configurable failure actions and integrated test report output supports DVT/EVT/ATP evidence reporting on first capture; full SCPI command set (USBTMC) and dual LAN for script-driven automated test sequences in redundant or load-balanced ATE network topologies.

Frequently Asked Questions

Should I size up to the UPO7204L instead?

If your fastest signal edges are below ~700 MHz and you don’t need the additional 1 GHz of single-channel-mode analog bandwidth, the UPO7104L has the same 10 GSa/s peak sample rate, the same 1 Gpts memory at single-channel mode, the same UltraAcq® acquisition engine, the same multi-machine sync architecture, and the same 11-protocol decode set as the UPO7204L — the 1 GHz vs 2 GHz analog bandwidth ceiling is the only meaningful difference on the spec sheet. The UPO7204L is worth the step-up when you’re working at the rise-time edge of 2 GHz analog signal-integrity, characterizing high-speed serial-link compliance (USB 3.0, PCIe Gen 1/2 region, MIPI), running jitter analysis on data rates above ~1 Gbps, or running ATE racks where headroom matters for measurement accuracy on customer designs.

What's the difference between standard capture rate and Sequence mode?

Standard capture rate (≥600,000 wfms/s via UltraAcq®) is the UPO7104L’s continuous real-time waveform acquisition rate. Sequence mode (2,000,000 wfms/s) uses segmented memory to capture multiple trigger-conditioned frames for post-capture replay — for rare-event hunting where the trigger is well-defined.
