3 Series MDO

Mixed Domain Oscilloscope

With the largest display in class, improved low-level signal measurement accuracy and industry-leading probe performance, the 3 Series MDO sets a new standard for bench oscilloscopes. Whether you’re testing your baseband design for IoT or just for simple EMI sniffing, the 3 Series has a unique true hardware spectrum analyzer built right in with superior RF test performance and guaranteed RF specifications.


  • Up to 1 GHz


  • 10 Mpoints


  • 2 or 4


  • Up to 5 GS/s

Industry-leading Probe Performance

Probes should not be overlooked as a key element in the measurement signal path. When you buy a 3 Series MDO you get the industry’s best probes free. Featuring industry-best loading of 3.9 pF 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

  • 250 MHz, 500 MHz or 1 GHz probe bandwidth depending on instrument bandwidth

Low-level signal measurement accuracy improved by as much as 40%

When you are measuring low level signals, it is critical to have a low instrument noise floor for better measurement accuracy. New front-end used in 3 series MDO can help you improve your noise measurements by as much as 40%. When you are evaluating an oscilloscope, be sure to carefully check the random noise specifications of the oscilloscope. Not all oscilloscopes are created equal, and not all oscilloscope manufacturers test and publish their random noise specifications.

A built-in spectrum analyzer

Whether you’re a spectrum analyzer expert or an occasional user, you’ll be able to put the built-in spectrum analyzer right to work. Unlike other oscilloscopes that offer FFT “spectrum analysis”, the 3 Series has a true spectrum analyzer built right in.

  • 1 GHz maximum frequency comes standard in every instrument, 3 GHz is optional

  • Industry's only true integrated spectrum analyzer hardware in its class

  • Ultra-wide capture bandwidth up to 3 GHz
