Overview

The UNI-T MSO1254HD is a 250 MHz 12-bit mixed signal oscilloscope designed for professionals requiring advanced measurement precision, faster rise-time visibility, and versatile protocol analysis. With 4 analog channels, 16 digital inputs, and deep 100 Mpts memory, it’s an excellent solution for analog, embedded, and power circuit design.

Combining Ultra Phosphor 3.0 display technology with real-time waveform capture rates up to 1,000,000 wfms/s, the MSO1254HD offers clarity and responsiveness unmatched in its class. From high-speed digital debugging to spectral and protocol decoding, this scope delivers performance engineers can rely on.

With its 250 MHz analog bandwidth and ≤1.4 ns rise time, the MSO1254HD captures faster edges and narrower pulses—ideal for RF control signals, clock lines, and high-speed switching behavior. 12-bit resolution ensures you don’t sacrifice detail when you zoom in on signal edges or noise floors.

Capture analog and digital activity with a single instrument. Correlate I/O timing, bus activity, and signal transitions using 4 analog channels and 16 digital inputs (with optional UT-M26 probe). Trigger on logic patterns, protocol frames, or custom timing windows to quickly isolate problems.

Supported protocol decoders:

• UART, SPI, I²C
• CAN, CAN-FD, LIN
• Audio I2S/TDM/Left-Justified

See transient events, jitter, and intermittent glitches with UNI-T’s Ultra Phosphor 3.0. This visualization engine offers up to 256 intensity levels and up to 1,000,000 wfms/s in sequence mode. Combined with zone triggering and touch gestures, waveform exploration is fast and precise.

Included with the MSO1000HD oscilloscopes:

• Switching Loss & SOA
• Ripple & Harmonics
• Startup/Shutdown Timing
• Power Quality

Pair UNI-T differential voltage probes with our current probes to analyze converters, regulators, and power stages directly.

The MSO1254HD’s built-in FFT engine enables spectral analysis with up to 1 million points. Analyze harmonic content, EMI signatures, or baseband frequency response using waterfall view and peak hold. Excellent for analog power supplies and RF signal chains.
