Overview

The UNI-T UPO2074HD is a 70 MHz 4-channel 12-bit high-resolution oscilloscope built around the R12™ native 12-bit ADC. It samples at 2.5 GSa/s with 100 Mpts memory depth standard, and Ultra Phosphor 3.0 acquisition pushes the waveform capture rate to 1,000,000 wfms/s in sequence mode — sixteen times the vertical detail of an 8-bit scope, held at full bandwidth without ERES averaging or sample-rate trade-offs. The 10.1-inch capacitive multi-touch display, on-instrument 4 Mpts FFT, 9 standard protocol decoders, and built-in WebServer round out a six-instrument bench in a single chassis.

The four-channel UPO2074HD adds simultaneous multi-rail observation to the entry-tier 12-bit price point — two analog rails plus a clock plus a control signal, all on screen at once, without compromising the 100 Mpts per-channel memory depth. For curriculum labs where one instrument has to cover everything from intro analog through embedded systems, this is the lift. Backed by the 3+2 warranty.

Detailed Features

R12™ — Native 12-Bit ADC at Full Bandwidth

R12™ is UNI-T's native 12-bit ADC architecture. It samples at 4,096 quantization levels — sixteen times the vertical detail of a conventional 8-bit oscilloscope — and holds that resolution at the full 70 MHz bandwidth and 2.5 GSa/s sample rate. There is no ERES averaging step, no sample-rate trade, and no asterisk on the spec sheet. For embedded prototyping and curriculum labs at the value tier, this is what makes the UPO2074HD a credible benchtop oscilloscope rather than an 8-bit hobby instrument with 12 bits printed on the front panel.

Ultra Phosphor 3.0 — 1,000,000 wfms/s Acquisition

Ultra Phosphor 3.0 is UNI-T's third-generation acquisition engine. Eight-channel parallel graphics processing at up to 20 Gbps drives a continuous capture rate of 250,000 wfms/s, with sequence mode pushing the rate to 1,000,000 wfms/s for trigger-conditioned events. 256-level grayscale persistence makes intermittent runts, glitches, and jitter visible as density gradients on screen rather than as occasional flashes that the eye misses. The same engine drives the digital trigger system — high sensitivity, low jitter, and zone trigger for isolating non-repeating signals.

× High-speed rendering surfaces fast or infrequent anomalies

6 Instruments in One

The UPO2074HD integrates six instrument functions into a single chassis: high-resolution oscilloscope, FFT spectrum analyzer with 4 Mpts and waterfall display, 4-digit digital voltmeter with DC/AC RMS modes, 7-digit hardware frequency meter, 9-protocol decoder and trigger engine, and the optional 12-parameter power analysis suite. With four analog channels feeding all of them, multi-rail converter validation and multi-bus protocol correlation happen on the same instrument without the cabling and context-switching of separate boxes.

× Six instrument functions on a single bench chassis

Deep Memory — 100 Mpts Standard

100 Mpts of memory comes standard, not as an upgrade. At 2.5 GSa/s that captures 40 ms of full-rate signal in a single acquisition — long enough to record a complete soft-start sequence, a fault-recovery transient, or a multi-frame burst without re-arming. Combined with hardware-accelerated mask testing, the 4-bit ERES enhanced-resolution mode, and uninterrupted recording of up to 125,000 frames, the deep memory turns long-running events from a sampling problem into a navigation problem.

× Zoom across long sequences without losing detail

All Protocols Included Standard

Nine serial-bus protocol decoders are included with every UPO2074HD: RS-232/UART, I²C, SPI, CAN, CAN-FD, LIN, FlexRay, SENT, and Audio. Each protocol supports both triggering and decoding, with event-list and search functions for navigating long captures. Decoded data appears alongside the analog waveform on the same trace — correlate a misbehaving I²C transaction with the supply-rail glitch that caused it, or align CAN-FD frames with the gate-drive event that triggered the fault recovery. No license fees, no time-boxed unlocks — the protocols are standard.

Power Analysis — Optional 12-Parameter Suite

The optional power-analysis package adds 12 measurement and analysis functions to the UPO2074HD: power quality, harmonic analysis, current harmonics, R_DS(on), switching loss, slew rate, safe operating area, modulation analysis, output ripple, startup/shutdown time, transient response, and power efficiency. For value-tier labs and curriculum work introducing students to switching-converter behavior, the analysis runs on the same instrument students already learned to use for time-domain debug.

× Power quality, switching loss, ripple, and SOA on the same instrument

Built-In Spectrum Analyzer — FFT to 4 Mpts

Standard enhanced FFT analysis runs at up to 4 Mpts across all channels with a frequency range from 0 to 1.25 GHz, four traces, four detection modes, and a waterfall display for tracking spectrum changes over time. Auto, manual, and threshold marker modes locate harmonics, spurs, and EMI sources without switching to a separate spectrum analyzer. For pre-compliance spot checks during board bring-up and switching-noise investigation during converter design, the on-instrument FFT closes a common bench-workflow gap.

× FFT with waterfall and four traces at up to 4 Mpts

56 Automated Measurements with Statistics

56 parameter measurements run continuously on every channel, with up to 27 measurements visible on screen and 39 single-channel parameters in the snapshot view. Statistics, histograms, and trend charts visualize each parameter's distribution over time. The new amplitude calculation strategy with top/bottom and burst-parameter handling makes the numbers correct on signals where naive measurement engines pick the wrong reference levels. No post-processing, no spreadsheet export — the answer is on the screen.

× Measure, visualize, and track parameter distributions on screen

10.1-Inch Touch UI and Full Connectivity

The 10.1-inch 1280×800 capacitive multi-touch display supports pinch, drag, zoom, rectangle-draw, and edit gestures alongside the traditional knobs and one-touch front-panel keys. Mouse and keyboard are supported in parallel. The peripheral set includes USB Host, USB Device, LAN, EXT Trig, AUX Out (Trig Out / Pass-Fail), and HDMI for projector or external-monitor display. SCPI is standard, the built-in WebServer enables browser-based remote control from a PC or mobile device, and firmware updates are free over the product's lifetime. For curriculum stations and shared lab benches, the WebServer lets an instructor mirror student displays to a central monitor via LAN without installing software on each station.
