More than just a powerful scope

Engineering designs today are a complex mix of processors, serial buses, and wireless interfaces. At the core of the MDO4000C is a reputable Tektronix oscilloscope paired with an expandable platform. Customize it to your testing needs. Add 16 logic channels, a 50 MHz arbitrary/function generator, protocol analysis, and an integrated true hardware 3 or 6 GHz spectrum analyzer to help tackle complex designs challenges.


  • Integrated triggered acquisition system - over 125 trigger combinations in the time AND frequency domains
  • 20 Mpoint record length with Wave Inspector® controls
  • True spectrum analyzer hardware enables real spectrum analysis
  • Expandable functionality ensures usefulness well into the future

Accurate Measurements Matter

Put simply, the MDO Series scopes are designed to make the most accurate measurements in the industry – providing an unrivaled view into your designs. The MDO4000C takes measurements on actual acquisition data, while many other instruments only offer a snapshot view by taking measurements on display data. It doesn’t end there. We guarantee more specifications than many of our competitors, ensuring the MDO4000C will give you total confidence in your measurements. After all, measurement accuracy impacts design integrity. Why settle for anything less than precise?

Industry Leading Probes – included with every purchase.

When examining the measurement signal path, probes are a key element that cannot be overlooked. When you buy an MDO4000C the industry’s best probes are included in the price. Featuring industry-best loading of 3.9 pF and bandwidth matched to your oscilloscope, the TPP-series probes will be your go-to probe for everyday use.


  • TPP-series probes included standard, one per analog channel
  • Industry-best capacitive probe loading of 3.9 pF
  • 500 MHz or 1 GHz probe bandwidth to match the scope’s bandwidth

Wireless Measurements - at a whole new level

Whether RF measurements make you smile or cringe, the MDO4000C oscilloscope with integrated hardware spectrum analyzer and SignalVu-PC software has you covered. Unlike oscilloscopes that offer FFT “spectrum analysis,” the MDO4000C with true spectrum analyzer provides a triggered acquisition system that is integrated across analog, digital and spectrum analyzer channels. You can perform RF measurements up to 6 GHz, and correlate events in the frequency domain with the time domain phenomena that caused them.


  • Available 3 or 6 GHz spectrum analyzer option
  • Industry’s only true integrated spectrum analyzer hardware
  • Spectrum analysis time-synchronized with analog and digital waveforms

Embedded Serial Bus Trigger, Decode and Analysis

A single serial bus signal often includes address, control, data, and clock information; making isolating events of interest difficult. The serial application modules for the MDO4000C series transform the oscilloscope into a robust tool for debugging serial buses with automatic trigger, decode, and search.


  • I2C, SPI, RS-232 / 422 / 485 / UART
  • CAN/CAN FD, LIN, FlexRay
  • MIL-STD-1553 , USB, Ethernet

Power Measurements and Analysis

The quest for ever-higher energy efficiency is placing new demands on designers and test instruments alike. Standby power constraints, higher switching speeds and signal ranges, lower-leakage semiconductor devices are pushing test conditions to new extremes. The MDO4000C offers power test solutions to address these ever evolving requirements.


  • Power loss measurement at switching device
  • Measurement and analysis of ripple and noise
  • Characterization of power semiconductor devices
  • Debugging active power factor correction circuits

Electromagnetic Interference (EMI) and Electromagnetic Compatibility (EMC)

When performing design EMI/EMC testing, there is always risk it will fail; leading to schedule and budget issues. The MDO4000C with built-in spectrum analyzer, and time correlation of analog, digital and RF signals enables you to perform pre-compliance testing in your lab - greatly improving the probability of a successful first pass of full EMI compliance testing.
