UNI-T MSO1254HD-S | 250MHz Mixed Signal Oscilloscope with 25 MHz Arbitrary Waveform Generator
Overview
The UNI-T MSO1254HD-S is a 250 MHz mixed signal oscilloscope with integrated 25 MHz signal generator, 12-bit high-resolution acquisition, and 4+16 channel mixed-signal input—all in a compact, field-ready form factor. With real-time 2.5 GSa/s sampling, Ultra Phosphor 3.0, and deep 100 Mpts memory, this oscilloscope delivers industry-leading waveform capture, signal generation, and analysis in a single instrument.
Ideal for engineers working in embedded systems, analog circuit design, power electronics, and lab instruction, the MSO1254HD-S supports protocol decoding, spectrum analysis, Bode plot functionality, and optional power analysis for switching and energy diagnostics.

Key Features
- 250 MHz Analog Bandwidth – Clean signal fidelity for analog, digital, and RF subsystems
- Integrated 25 MHz Arbitrary Waveform Generator – Built-in stimulus source with 14-bit resolution
- 12-bit ADC Resolution – See what 8-bit scopes miss with 4096 vertical levels
- 2.5 GSa/s Sampling – Real-time acquisition for high-speed analysis
- 4+16 Channels – Time-correlated analog and digital signal capture
- Ultra Phosphor 3.0 – Up to 1M wfms/s sequence capture, 256-level grading
- Bode Plot + PSRR Analysis – Visualize frequency and phase response directly
- Standard Protocol Decoding – UART, SPI, I²C, CAN, CAN-FD, LIN, Audio
- FFT Spectrum Tools – 1Mpt FFT, 4 traces, peak detection, and waterfall
- Power Analysis – Perform switching loss, ripple, and harmonic tests
- USB-C PD Powered – Efficient, portable, and easy to deploy
Built-in 25 MHz Waveform Generator
The MSO1254HD-S’s signal generator supports sine, square, ramp, pulse, noise, DC, and 200+ arbitrary waveforms with sweep, modulation, and burst capabilities. Perfect for injecting test signals into amplifiers, filters, microcontrollers, or power supplies.
- 14-bit output resolution at 200 MSa/s
- Modulation formats: AM, FM, ASK, FSK
- Waveform sweep with start/stop frequency control
- Library of 200+ built-in arbitrary waveforms
This eliminates the need for a separate signal source—ideal for development labs and classrooms.

Optimized for Engineering Instruction
With waveform generation and analysis in one device, students can explore analog systems, test embedded designs, and verify digital protocols without switching tools. Educators can demonstrate frequency response, signal integrity, and real-world measurements interactively.
Its USB-C power input, wall-mountable form, and intuitive UI make it ideal for classroom labs, mobile test carts, and training centers.

Waveform Visualization and Protocol Debugging
Ultra Phosphor 3.0 enables fast updates and deep signal insight with waveform intensity grading and up to 1,000,000 wfms/s in sequence mode. Combine this with visual zone triggering and 16 digital inputs for true embedded system validation.
Protocol decoding is included for UART, SPI, I²C, CAN, LIN, CAN-FD, and Audio interfaces. Event search, trigger filtering, and bus correlation features support fast system debug.

Spectrum, Bode, and Power Analysis
Switch from time to frequency domain instantly using the FFT engine. Perform stability measurements using Bode plot mode, or unlock power analysis functions for ripple, harmonics, and switching loss tests. Requires differential voltage probes and current probes for complete energy characterization.
