What's in the Box

Key Technologies & Functions

1. Mixed Signal Analysis (4+16 Channels)

The MSO2204-S's defining feature is its ability to simultaneously capture and correlate 4 analog channels and 16 digital channels. This integrated logic analyzer capability, provided by the included UT-M15 probe, simplifies debugging of embedded systems by letting you view analog waveforms alongside digital bus signals, decode protocols, and perform precise timing measurements .

2. Ultra Phosphor Technology

UNI-T's original Ultra Phosphor technology provides a vivid grayscale display that shows signal intensity over time, revealing rare anomalies and signal characteristics that standard digital oscilloscopes miss. This three-dimensional waveform data of amplitude, time, and intensity gives you deeper insight into signal behavior .

3. Fast Acquire Mode with 1,000,000 wfms/s

Powered by innovative digital signal parallel processing technology, the MSO2204-S achieves an ultra-high waveform capture rate of 1,000,000 wfms/s in Fast Acquire mode. This dramatically increases the probability of capturing glitches, runt pulses, and other infrequent events .

4. Full-Memory Hardware Decoding

Experience lightning-fast protocol decoding with deep 56Mpts memory. The full-memory hardware decoding capability reduces decoding time from seconds to milliseconds, ensuring real-time decoding and significantly improving problem diagnosis efficiency for protocols like I²C, SPI, UART, CAN, and LIN .

5. Built-in 50MHz Arbitrary Waveform Generator

The integrated dual-channel AWG eliminates the need for a separate function generator. Use it to:

• Generate standard waveforms (sine, square, ramp, pulse)

• Create arbitrary waveforms for custom stimulus

• Produce noise for margin testing

• Output DC signals for biasing

• Perform Bode plot analysis to characterize filter and amplifier frequency response 

6. Enhanced FFT Analysis

With 4M-point FFT, you can seamlessly convert time-domain signals into frequency-domain information. Advanced viewing modes—full-screen, split-screen, and waterfall charts—allow comprehensive analysis of:

• Harmonic content and distortion

• Noise in DC power supplies

• Vibration characteristics

• Spectral components 

7. Area Trigger

The advanced area trigger function captures signals that enter or exit a user-defined area on the screen—ideal for capturing occasional and complex signals that traditional triggers might miss .

8. Multi-Scopes Technology

Independent time base per channel with split-screen display allows you to view signals of vastly different frequencies simultaneously, each with optimal horizontal scaling. This is invaluable for analyzing relationships between slow control signals and fast data streams .

9. Intuitive Touchscreen Interface

The 8-inch capacitive touchscreen supports multi-touch gestures including click, slide, zoom, edit, and drag, providing a smartphone-like experience. Traditional button and knob controls are retained for users who prefer physical controls .

10. Remote Control via Web Server

The built-in web server allows you to access and control the oscilloscope remotely via a standard web browser on a PC or mobile device, making it ideal for collaborative work or remote monitoring .
