UPO1082HD 80 MHz 2Ch 12-Bit Digital Storage Oscilloscope

Overview

The UPO1082HD is an 80 MHz, 2-channel digital oscilloscope built around UNI-T's R12™ 12-bit ADC architecture, with 1.25 GSa/s real-time sample rate, 100 Mpts memory depth, and a 7-inch capacitive touchscreen. Native 12-bit resolution gives 4,096 vertical levels — 16× the detail of an 8-bit instrument — enough to resolve power-supply ripple, sensor outputs, and small AC signals riding on DC offsets where 8-bit scopes lose them in the quantization floor.

USB-C power-bank operation off any 12V/3A PD source, a 1.56 kg chassis, and a VESA 100×100 mm mounting pattern make the UPO1082HD a real bench scope that fits where a bench scope usually doesn't — service vehicles, field cabinets, teaching benches with no rear AC outlet.

Detailed Features

R12™ — Real 12-Bit Architecture

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 80 MHz bandwidth and 1.25 GSa/s sample rate. There's no ERES averaging step, no sample-rate trade, and no asterisk on the spec sheet. Background noise is 60 µVrms at full bandwidth, low enough that the Real 12-bit resolution actually shows up on the screen instead of being buried in the noise floor.

For switching-power-supply ripple, sensor signal conditioning, audio-band measurements, and any application where a small AC signal rides on a larger DC offset, the resolution gain is the difference between a usable trace and quantization steps.

Built-In Power Analysis

Power analysis is standard, not an optional package. Twelve measurement functions cover power quality, current harmonics, switching loss, R_DS(on), SOA, modulation, output ripple, startup/shutdown time, conversion rate, and power efficiency. Connect the appropriate voltage and current probe (UT-P30 / UT-P31 / UT-P32 differential probes and the UT-P40 series current probes are available as accessories), pick the analysis type, and the oscilloscope drives the rest of the workflow.

For an oscilloscope at this tier, this is the line where the UPO1082HD stops behaving like a value-tier instrument. Most scopes in this price band expect a separate power analyzer or a paid software unlock; this one ships with the analysis built in.

Protocol Decoding Included

RS-232/UART, I²C, SPI, CAN, and LIN trigger and decode are standard — no protocol licenses, no add-on packages. Decoded bus traffic overlays the waveform with field-level annotation, and event-list view exports the captured frames for offline analysis. Up to four parallel decode windows run at once, useful when correlating an SPI command stream against a CAN response on a mixed automotive or industrial control board.

× 5 protocol decoders, included standard

56 Automated Measurements + DVM + Frequency Counter

56 automated measurements cover voltage, time, frequency, edges, burst, setup-and-hold, delay, and phase, with up to 21 parameters on screen simultaneously and statistics (mean, max, min, standard deviation, count) available per parameter. Histograms and trend charts make distribution and drift visible without exporting to a PC.

A 4-digit DVM (DC, AC RMS, AC+DC RMS) and a 6-digit hardware frequency counter run on the same channels in parallel with scope acquisition — no probe swapping, no separate instrument.

USB-C Power-Bank Operation and VESA Mounting

The UPO1082HD runs off any 12V/3A PD-protocol USB-C power source. A field-rated power bank, a vehicle PD adapter, or a workbench USB-C charger all qualify. Combined with the 1.56 kg chassis and a VESA 100×100 mm mounting pattern on the rear panel, the scope deploys on a service truck, a flight-test rack, a teaching cart, or a wall-mounted bench where standard AC-powered scopes don't fit.

Power consumption is 65 W maximum.

Applications

Embedded Systems Development (R&D)

• Mixed-signal debug on microcontroller boards using the five included protocol decoders alongside 12-bit analog capture.
• Firmware bring-up with 100 Mpts memory holding entire boot sequences without a sample-rate trade.
• Sensor-conditioning circuit characterization where 8-bit quantization noise hides the actual signal.
• USB-C operation lets the scope move with the prototype to lab, conference room, or customer site.

Power-Supply Bench Work

• Switching-supply ripple measurement at µV scale, made visible by 12-bit resolution and the 60 µVrms noise floor.
• Switching-loss and R_DS(on) measurement using the standard power-analysis package, no software unlock required.
• Startup/shutdown timing with sequence-mode capture up to 500,000 wfms/s.
• Output-ripple and harmonic content with the 1 Mpts FFT.

Teaching Lab and Trade-School Curriculum (Education)

• Multi-station deployment without compromising on resolution: a value-tier 12-bit oscilloscope on every bench instead of sharing 8-bit instruments.
• Same UI as flagship UPO/MSO HD scopes — students learn an instrument they'll see in industry.
• HDMI projection mirrors the screen for live demonstration without a USB capture step.
• VESA wall-mounting frees bench surface for breadboards and DUTs in tight teaching spaces.

Field Service and Mobile Applications

• Service-truck installation off vehicle 12V via USB-C PD adapter — no inverter, no AC outlet required.
