Product Introduction
The NI PXIe-4610 is a two-channel PXI Express power amplifier designed for automated test, dynamic signal testing, electromechanical validation, and laboratory measurement systems. It provides amplified signal output capability for applications where the output level of a standard signal generation device is not sufficient to directly drive the device under test.
Featuring two independent power amplifier channels, differential AC-coupled inputs, PXI Express integration, and NI-DAQmx software support, the PXIe-4610 can be integrated with signal generation and data acquisition instruments to build complete stimulus-and-measurement systems.
Product Overview
The NI PXIe-4610 is designed to provide power amplification within modular PXI Express test systems. It can be used between a compatible signal source and a load or device under test when additional drive capability is required.
