The Tektronix MDO34/3-BW-350 is a 350 MHz 4-channel 3 Series Mixed Domain Oscilloscope that integrates time-domain, frequency-domain, and optional logic analysis into a single compact instrument. Designed to simplify modern debugging workflows, it provides synchronized visibility across analog, digital, and RF signals, enabling engineers to identify issues faster while reducing bench clutter and setup complexity.

Advanced Waveform Capture & Analysis

Tektronix FastAcq™ technology dramatically increases waveform capture rates, making it easier to detect intermittent glitches, runt pulses, and timing anomalies. Advanced triggering, search, and analysis tools help engineers isolate root causes quickly—even within long waveform records.

Integrated Spectrum Analyzer

Each 3 Series MDO includes a dedicated, hardware-based spectrum analyzer that is fully synchronized with the oscilloscope time domain. This architecture enables accurate correlation of RF behavior with analog and digital activity, supporting EMI troubleshooting, wireless validation, and IoT system analysis.

Touch‑Optimized User Interface

Scopes have included touch screens for years, but the touch screen has been an afterthought. The 3 Series MDO 11.6" display includes a capacitive touchscreen and provides a user interface truly designed for touch.
The touch interactions that you use with phones and tablets, and expect in a touch enabled device, are supported in the 3 Series MDO.
