Product Introduction
The NI PXIe-6124 is a high-speed simultaneous-sampling multifunction data acquisition (DAQ) module designed for PXI Express automated test, dynamic signal acquisition, transient recording, and precision measurement applications. As part of the National Instruments S Series DAQ family, the PXIe-6124 provides dedicated analog-to-digital converters for each input channel, ensuring accurate phase alignment and time-correlated measurements.
Featuring four simultaneous analog input channels with sampling rates up to 4 MS/s per channel, 16-bit resolution, digital I/O, and advanced timing resources, the PXIe-6124 is ideal for high-speed waveform capture, power electronics testing, aerospace validation, and industrial automation.
Product Overview
The PXIe-6124 is engineered for engineers and researchers requiring simultaneous acquisition of multiple high-speed analog signals. Unlike multiplexed DAQ devices, every analog input channel includes its own ADC, eliminating channel-to-channel delay and providing highly accurate phase measurements.
Built on the PXI Express architecture, the PXIe-6124 offers high-bandwidth communication, deterministic synchronization, and seamless integration with other PXI instruments. Combined with NI-DAQmx and LabVIEW software, it enables rapid development of scalable automated test and measurement systems.
