The 34461A 6.5 digit multimeter is the next-generation replacement for the Keysight 34401A digital multimeter (previously Agilent 34401A). 34461A turns lots of data into results quickly with Truevolt Series DMMs' new graphical display, advanced analysis modes, and built-in math functions. It offers Truevolt technology that provides measurement and display capabilities as you've never experienced before. Keysight's exclusive Truevolt technology is based on patented analog to digital converter technology and eliminates extraneous factors like noise, injected current, and input bias current from measurements to give you the highest measurement accuracy. This new technology allows you to focus more on the quality of your designs rather than worrying about the quality of your measurements.
