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.
