The Best Just Got Better The Keysight 34460A and 34461A 6-1/2 digit digital multimeters (DMMs) offer Truevolt technology that provides measurement and display capabilities like 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 confidence in your 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.The new graphical display capabilities allow you to easily display, save and document your results. Truevolt Technology Real-world signals are never flat. They have some level of AC signal riding on top from power line noise, other environmental noise, or injected current from the meter itself. How well a DMM deals with extraneous factors and eliminates them from the true measurement makes a big difference to its accuracy. Using patented analog-to-digital converter technology, Keysight Truevolt Series DMMs account for measurement errors created by these real-world factors, so engineers can be confident in their measurements. Save and document your DMM's data to your PC or mobile device using your preferred I/O Capture a digitized record, log measurements for longer periods under PC control or upload data captured directly from the instrument. Export data from a single DMM, or multiple DMMs with time alignment, to popular tools such as Microsoft Excel, Microsoft Word and MATLAB. Simplify test documentation and data analysis without the hassles of programming. 34460A: USB included.
