Overview

The 7451A is a high-performance and low-cost digital multimeter of 5 1/2-digit display (maximum display of 319999) equipped with new functions. Since the newly developed A/D converter has allowed arbitrary integration time setting, the 7451A is ideal for average measurement of the pulsed current and voltage of mobile phones and LCDs. It is also adaptable to various applications with a wide range of sampling rate from 5,000 readings per second to 1 reading per hour. Furthermore, the 7451A is capable of 2-channel voltage measurement and 1-channel current measurement with the DCV-Bch input, contributing to higher measurement system performance. Not only a GPIB interface but also a USB interface is mounted as standard, allowing easy system configuration.
