Product Introduction
The NI PXI-6133 is a high-speed S Series multifunction data acquisition (DAQ) module designed for synchronized analog measurement, automated testing, transient signal acquisition, and research applications. It provides eight simultaneously sampled analog input channels, allowing engineers to acquire multiple signals without the channel-to-channel timing skew associated with multiplexed architectures.
Featuring 14-bit resolution, sampling rates up to 3 MS/s per channel, eight simultaneous analog inputs, digital I/O, and counter/timer functionality, the PXI-6133 provides a versatile measurement platform for demanding PXI-based data acquisition and automated test systems.
Product Overview
The NI PXI-6133 belongs to the NI S Series simultaneous-sampling multifunction DAQ family. It is designed for applications where accurate timing relationships between multiple analog signals are important.
Unlike multiplexed DAQ devices that share an analog-to-digital converter across several channels, the PXI-6133 uses simultaneous sampling architecture. This enables all analog input channels to acquire data at the same time, making the module particularly suitable for phase-sensitive measurements, transient events, multi-channel waveform acquisition, and dynamic system testing.
The combination of high-speed analog acquisition, digital I/O, counter/timers, PXI synchronization, and NI software support enables the PXI-6133 to serve as a core measurement device in automated test, research, industrial, automotive, and aerospace systems.
