5½-digit DMM for comfortable system use

Fast, precise, many trigger functions

The DMM 7451A is a high-speed 5½-digit multimeter with variable integration time and support multiple applications. It implements a sampling rate of up to 5000 samples per second and feature a high resolution DCI measurement of 10 nA and a two-channel DCV measurement. Many trigger functions allow easy data capturing.

Features & benefits

5½-digit display

Variable integration time of 100 µs to 10 s

The integration time can be set from 100μs to 10s, which allows you to easily measure the average current of cellular phones or LCDs. The newly developed A/D converter of which integration time can be set to any values is based on the analog integration technique, so that it provides precise average measurement data, differently from the digital method using a discrete sampling.

Variable integration time

The variable integration time setting allows an optimal adaption of the measurement window to DUT's waveform profile.

Fast sampling

Up to 5000 readings/s

By adopting the newly developed variable integration time A/D converter, the 7451A realize the highest sampling rate of 5000 readings per sec. with 3½-digit resolution respectively. The sampling interval can be set from 50μs to 3,600s for the 7451A. It hosts a data memory for 10000 data.

Event controlled data capture

Event controlled data capture

The pre-trigger is used to capture data before the trigger event. This is helpful for analyzing abnormal events.

10nA DCI measurement

Two-channel DCV measurement

The 7451A is stable in low current measurement and also highly sensitive with the minimum resolution of 10nA. This is useful for measurements of portable devices with low current consumption. With the DCV-Bch input (10V range fixed), current measurement and two-channel voltage measurement can be switched, which enhances the measurement throughput.

A multifarious set of Trigger modes increase its precise data capture capabilities.

Simple interoperability

USB/GPIB/comparator interface and ext. Trigger

The 7451A is equipped with USB and GPIB interface as standard. Beside its powerfull internal Trigger capabilities an external Trigger input, a Complete output and a Comparator output enable precise synchronization with other T&M instruments in system use.
