Like its predecessors, the 5730A calibrates a wide range of digital multimeters, up to long-scale 8.5 digit DMMs, as well as RF voltmeters when equipped with the wideband option. But this new model features improved specifications that will help you increase test uncertainty ratios (TURs) and increase test confidence. What’s more, the improved specifications will reduce your need to guardband, giving you confidence and peace of mind in your calibrations.
