3 Series MDO

Mixed Domain Oscilloscope

Experience a big, high definition display in a compact, portable scope. An award winning, made-for-touch interface turns the learning curve into a step function. The unique built-in spectrum analyser option makes it great for RF analysis.

The biggest display in its class, and remarkable user interface

See how the 3 Series MDO user interface helps you work better and faster

With the same made-for-touch user interface technology as the award-winning 5 Series along with the largest display and highest resolution display in its class, the 3 Series MDO works how a scope should work.

11.6 inch HD display
Pinch, tap, swipe capacitive touchscreen

Compact, yet packed with capabilities

Its only 6 inches (15cm) deep but the 3 Series MSO is a lot of oscilloscope. It gives you the tools you need to validate and troubleshoot complex embedded systems.
