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.

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.

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
