Digital VoltmeterSee Digital Voltmeter Products
Digital voltmeters (DVMs) are usually designed around a special type of analog-to-digital converter called an integrating converter. Voltmeter accuracy is affected by many factors, including temperature and supply voltage variations. To ensure that a digital voltmeter's reading is within the manufacturer's specified tolerances, they should be periodically calibrated against a voltage standard such as the Weston cell.

The Keysight 53140 Series is a full-featured CW microwave counter, a true power meter, and a dc DVM all in one small convenient package. It is the ideal tool for installation and maintenance of point-to-point microwave links as three of the most commonly made field measurements are combined into one instrument. In ATE systems, the three-in-one 53140 Series will also save valuable rack space.
